Hi everyone, it passed time since a last submision.

This is an own design representing the deatheaters followers of Voldemort in Harry Potter series :lol: basing in the argument very possibly Ms Rowling inspired in nazis to state D.E. ideals of blood purity, even the young Tommy looks A LOT LIKE Hitler :XD:
That's shows how her ideas are the awesome good creating stories and groups of characters.

This work shows a fusion of swastika nazi version with Slytheryn's "S" holding the form of the snake, possibly Nagini and of course this one in the green field.

Hope you like it.

Northrop Lockheed B-3 XR

B-3 Long Range Strike Platform

Under current plans, the B-52, along with the younger B-1B Lancer and the new stealthy B-2 Spirit, will be kept around until approximately 2037, by which time the Air Force calculates that attrition will have reduced the fleet below the minimum 170 aircraft. The B-52s may fly to 2045.

Based on current operating procedures, attrition models, and service lives, the total bomber inventory is predicted to fall below the required 170 aircraft fleet by 2037. This date will become the target Initial Operational Capability (IOC) date for a follow-on to the current bomber capability, and an acquisition process can be planned by backing up from this date. Based on current projections for airframe economic service life and forecast mishap rate, initiating a replacement process no later than 2013 will ensure a capability to fill the long-range air power requirement as the current systems are retired. There are, however, additional concerns besides service life and mishap rates that could shift this replacement timeline. Changes in employment concepts, driven by technological advances in munitions and threats, or improvements in industry’s ability to perform cost effective major structural extensions could extend the today’s bomber force well beyond current projections. This may shift the acquisition timeline for a replacement capability further into the future.

The Light Bomber (Manned) concept calls for a medium-sized aircraft that blends the advantages of a tactical fighter with a strategic bomber to develop a medium/long range, high payload capability (inter-theater) affordable bomber. The aircraft will utilize some level of low-observable technology to obtain an effective yet affordable aircraft which can provide for multiple/heavy weapons carriage and launch for missions requiring real time decision making/replanning or autonomous operations. Cost would be controlled by utilizing off-the-shelf systems and affordable stealth technologies (JSF technology). Logistic support would be enhanced by maximizing commonality of support equipment with existing systems.

The Bomber Industrial Capabilities Study was directed by Congress, chartered by the DOD, and conducted by The Analytic Sciences Corporation (TASC). The study concluded that building a new bomber type, a B-3, could easily cost in excess of $35 billion for research and development alone (with unit flyaway costs about the same as a B-2). Technology concepts from the USAF Scientific Advisory Board's (SAB) New World Vistas and technology concepts submitted for the 2025 Study were reviewed and concepts harvested from these efforts included the Future Attack Aircraft. This concept envisions a 500-nm-range manned or unmanned aircraft that would use stealth technology (both RF and IR) to reach a target and employ laser or high-power microwave (HPM) weapons. An unmanned aircraft with a "tunable" HPM weapon could provide either the nonlethal or lethal punch SAF needs in the constabulary mission.

Two concepts under consideration by Air Force Materiel Command included:

* Multi-mission - Manned, multi-role capability, radius > 450+ range (hi-med-hi), Payload??, medium threat, Unit Flyaway Price (UFP) <$75M (BY00) Number of Concepts Scored: 3 (‘96); 1 (‘97); 1 (‘98)
* 10.2 Deep Strike - Manned, 1000NM < radius < 2000NM, 12-24 klbs, high-med-high or hi-lo-hi, med-high threat, $50M < UFP < $250M (BY00)

A 1999 RAND Corporation study articulated a rationale for acquiring a Mach 2 supersonic bomber with the following characteristics

* unrefueled range of 3,250 nmi
* weight of 290,000 to 350,000 pounds each
* payload of 15,000 to 20,000 pounds
* support of 37 to 40 percent of the current USAF tanker fleet and 100 air superiority fighters.

The Mach 2 bomber could attack targets almost anywhere in the world while operating from well-protected, permanent bases on US and UK territory. A total inventory of approximately 80 to 105 of these Mach 2 bombers could deliver enough PGMs (about 560 tons per day) to replicate the USAF Desert Storm effort.

A design I did for the 2012 Ron Paul movement. I wanted to do something that would grab people's attention when they see it. Not commissioned from Ron Paul or his campaign but from a group of people who want to make people informed of the truth and the availability of other options other than what Fox News tells you about. We got lost in the day to day routines of working, going to school, feeding our families, etc and lose the interest to research and understand what is going on in the country we live in. I appreciate any feedback about the art and understand that there are those who disagree with Dr. Ron Paul's beliefs and that is one of the very freedoms he looks to preserve. So please feel free to criticize my work and give any advice(I am new to this type of art) that might make it better but please keep the political debates to other forums. Thanks for taking the time to look!

The MQ-9 Reaper (originally the Predator B) is an unmanned aerial vehicle (UAV) developed by General Atomics Aeronautical Systems (GA-ASI) for use by the United States Air Force, the United States Navy, and the British Royal Air Force. The MQ-9 is the first hunter-killer UAV designed for long-endurance, high-altitude surveillance.[4]

The MQ-9 is a larger and more capable aircraft than the earlier MQ-1 Predator. It can use MQ-1's ground systems. The MQ-9 has a 950-shaft-horsepower turboprop engine, far more powerful than the Predator's 115 hp (86 kW) piston engine. The increase in power allows the Reaper to carry 15 times more ordnance and cruise at three times the speed of the MQ-1.[4]

In 2008 the New York Air National Guard 174th Fighter Wing began to transition from F-16 piloted planes to MQ-9 Reaper drones, which are capable of remote controlled or autonomous flight, becoming the first all-robot attack squadron.[5][6][7]

Then U.S. Air Force Chief of Staff General T. Michael Moseley said, "We've moved from using UAVs primarily in intelligence, surveillance, and reconnaissance roles before Operation Iraqi Freedom, to a true hunter-killer role with the Reaper."[4]

As of 2009[update] the U.S. Air Force’s fleet stands at 195 Predators and 28 Reapers.[2]

Design and development

With the success of the MQ-1 in combat, General Atomics anticipated the Air Force's desire for an upgraded aircraft and, using its own funds, set about redesigning Predator.

Prototype "Predator B"

General Atomics began development of the Reaper with the "Predator B-001", a proof-of-concept aircraft, which first flew on 2 February 2001. The B-001 was powered by a Garrett AiResearch TPE-331-10T turboprop engine with 950 shp (712 kW). It had a standard Predator airframe, except that the wings were stretched from 48 feet (14.6 m) to 66 feet (20 m). The B-001 had a speed of 220 kts (390 km/h) and could carry a payload of 750 pounds (340 kilograms) to an altitude of 50,000 feet (15.2 kilometers) with an endurance of 30 hours.[8]

GA refined the design, taking it in two separate directions. The first was with a jet-powered version. The "Predator B-002" was fitted with a Williams FJ44-2A turbofan engine with 10.2 kN (2,300 lbf, 1,040 kgf) thrust. It had payload capacity of 475 pounds (215 kilograms), a ceiling of 60,000 feet (18.3 kilometers) and endurance of 12 hours. The U.S. Air Force has ordered two airframes for evaluation, delivered in 2007.[9]

The second was the "Predator B-003", referred to by GA as the "Altair", which has a new airframe with an 84-feet (25.6 m) wingspan and a takeoff weight of about 7,000 pounds (3,175 kilograms). Like the Predator B-001, it is powered by a TP-331-10T turboprop. This variant has a payload capacity of 3,000 pounds (1,360 kilograms), a maximum ceiling of 52,000 feet (15.8 kilometers), and an endurance of 36 hours.[10][11]

Air Force version
First MQ-9 arrives at Creech AFB, March 2007.

In October 2001, the US Air Force signed a contract with GA to purchase an initial pair of Predator B-003s for evaluation, with follow-up orders for production machines. The first test MQ-9s were delivered to the Air Force in 2002. The name "Altair" did not follow the aircraft into testing, with the Air Force continuing to refer to the system as "Predator B" until it was renamed Reaper ("Altair" instead became the designation for the unarmed NASA version); this is confusing, however, as the manufacturer uses the term to refer to the smaller B-001 prototype.[8]

Operators, stationed at bases such as Creech Air Force Base, near Las Vegas, can hunt for targets and observe terrain using a number of sensors, including a thermal camera. One estimate has the on-board camera able to read a license plate from two miles away.[12] An operator's command takes 1.2 seconds to reach the drone via a satellite link. The MQ-9 is fitted with six stores pylons. The inner stores pylons can carry a maximum of 1,500 pounds (680 kilograms) each and allow carriage of external fuel tanks. The mid-wing stores pylons can carry a maximum of 600 pounds (270 kilograms) each, while the outer stores pylons can carry a maximum of 200 pounds (90 kilograms) each. An MQ-9 with two 1,000 pound (450 kilogram) external fuel tanks and a thousand pounds of munitions has an endurance of 42 hours.[11] The Reaper has an endurance of 14 hours when fully loaded with munitions.[4] The MQ-9 carries a variety of weapons including the GBU-12 Paveway II laser-guided bomb, the AGM-114 Hellfire II air-to-ground missiles, the AIM-9 Sidewinder.[13] and recently, the GBU-38 JDAM (Joint Direct Attack Munition). Tests are underway to allow for the addition of the AIM-92 Stinger air-to-air missile . Air Force believes that the Predator B will give the service an improved "deadly persistence" capability, with the UAV flying over a combat area night and day waiting for a target to present itself. In this role an armed UAV neatly complements piloted strike aircraft. A piloted strike aircraft can be used to drop larger quantities of ordnance on a target while a cheaper UAV can be kept in operation almost continuously, with ground controllers working in shifts, carrying a lighter ordnance load to destroy targets.[11]

By October, 2007 the U.S. Air Force owned nine Reapers,[14] and was expected to decide whether to order full-rate production in 2009.[4] On 18 May 2006, the Federal Aviation Administration (FAA) issued a certificate of authorization that allows the MQ-1 and MQ-9 aircraft to fly in U.S. civilian airspace to search for survivors of disasters. Requests had been made in 2005 for the aircraft to be used in search and rescue operations following Hurricane Katrina but, because there was no FAA authorization in place at the time, the planes were not used.[15]

In September 2007, the MQ-9 deployed into Iraq at Balad, the largest U.S. air base in Iraq.[16] On 28 October 2007 the Air Force Times reported an MQ-9 had achieved its first "kill", firing a Hellfire missile against "Afghanistan insurgents in the Deh Rawood region of the mountainous Oruzgan province. The strike was 'successful'," the United States Central Command Air Forces said.[17]

Critics have stated that the USAF's insistence on qualified pilots flying UAVs is a bottleneck to expanding their deployment. Air Force Major General William Rew stated on 5 August 2008, "For the way we fly them right now"—fully integrated into air operations and often flying missions alongside manned aircraft—"we want pilots to fly them."[18] This may be exacerbating losses of Air Force aircraft, in comparison with US Army operations.[19]
An MQ-9 taking off in Afghanistan

The typical MQ-9 system consists of multiple aircraft, ground control station, communications equipment and links, maintenance spares, and military (or contractor) personnel. The crew consists of a pilot and sensor operator. To meet combat requirements, the MQ-9 tailors its capabilities using mission kits of various combinations of weapons and sensors payloads. The Raytheon AN/AAS-52 multi-spectral targeting sensor suite includes a color/monochrome daylight TV, infrared, and image-intensified TV with laser rangefinder/target designator to designate targets for laser guided munitions. The Synthetic Aperture Radar system enables GBU-38 JDAM targeting, is capable of very fine resolution in both spotlight and strip modes, and has ground moving target indicator capability.

[edit] Navy version

General Atomics designed a naval version of the Reaper, named the "Mariner", for the U.S. Navy's Broad Area Maritime Surveillance (BAMS) program requirements. The design would have an increased fuel capacity in order to have an endurance of up to 49 hours.[20] Proposed variations on the ultimate design included one designed for carrier operations with folding wings for carrier storage, shorter and more rugged landing gear, an arresting hook, cut-down or eliminated ventral flight surfaces and six stores pylons with a total load of 3,000 pounds (1,360 kilograms).[11] The Northrop Grumman RQ-4N was announced the BAMS winner.

The US Customs and Border Protection has ordered a "Maritime Variant" of the MQ-9.[21]

[edit] NASA version
NASA version Altair
NASA version Ikhana

NASA had initially expressed some interest in a production version of the B-002 turbofan-powered variant,[11] but instead has leased an unarmed version of the Reaper, which carries the GA-ASI company name "Altair". Altair is one of the first 3 "Predator-B" airframes. The other 2 airframes, known as "Predator-B 001" and "Predator-B 002", had a maximum gross weight of 7,500 pounds. Altair differs from these models in that it has an 86-foot (26 m) long wingspan (20 feet greater than early and current MQ-9's). The Altair has enhanced avionics systems to better enable it to fly in FAA-controlled civil airspace and demonstrate "over-the-horizon" command and control capability from a ground station. These aircraft are used by NASA's Earth Science Enterprise as part of the NASA ERAST Program to perform on-location science missions.[22]

In November 2006, NASA's Dryden Flight Research Center obtained an MQ-9 from General Atomics Aeronautical Systems Inc.. The aircraft has been named Ikhana and its main goal is the Suborbital Science Program within the Science Mission Directorate. NASA also acquired a ground control station in a mobile trailer.[23] This aircraft was used extensively to survey the Southern California wildfires in 2007. The data was used to deploy firefighters to areas of the highest need.

Homeland Security version
An MQ-9 of the U.S. Customs and Border Protection agency.
UAV Operators at Balad Camp Anaconda, Iraq, April 20, 2005.

The United States Department of Homeland Security initially ordered one Predator B for border patrol duty, referred to as MQ-9 CBP-101. It began operations 4 October 2005, but on 25 April 2006, this aircraft crashed in the Arizona desert. The NTSB determined (Record Identification: CHI06MA121[24]) that the cause of the crash was most likely a pilot error by the aircraft's ground-based pilot in the use of a checklist. During its operational period, the aircraft flew 959 hours on patrol and had a part in 2,309 arrests. It also contributed to the seizure of four vehicles and 8,267 pounds of marijuana.[25] Because of these successes, a second Predator B, called "CBP-104" (initially referred to as "CBP-102"), was delivered in September 2006, and commenced limited border protection operations on 18 October 2006. The program was further expanded on 16 February 2009, including Canadian border patrols where US officials were concerned about the explotation of the border by "drug smugglers, migrants and terrorists"[26].

The CBP-101 was equipped with the Lynx SAR, AX-15 payload, ARC-210 radios, and other sensors and communications equipment; CBP-104 was enhanced with Ku band satellite command and control link and MTS-A EO/IR sensors.[25]

The President’s FY 2006 Emergency Supplemental budget request added $45 million for the Predator B program, and the FY 2007 Homeland Security Appropriations bill adds an additional $20 million. In October 2006, GA-ASI announced a $33.9 million contract to supply two more Predator B systems by Fall 2007.[27]

U.S. Customs and Border Protection has Six [28]operational MQ-9s. One based in North Dakota, at the UAS Operations Center in Grand Forks, four in Arizona, at the UAS Operations Center in Sierra Vista and one based at Fort Drum, N.Y.[3] The aircraft are equipped with GA-ASI's Lynx Synthetic Aperture Radar (Lynx SAR info/web page) and Raytheon's MTS-B ElectroOptical/Infrared sensors.[29]

[edit] International versions


In September 2006, the General Atomics Mariner demonstrator aircraft was operated by the Australian Defence Science and Technology Organisation (DSTO) in an exercise designed to evaluate the aircraft's ability to aid in efforts to stem illegal fishing, drug running and illegal immigration. The Mariner operated from RAAF bases Edinburgh, South Australia and Learmonth, Western Australia in conjunction with a Royal Australian Navy Armidale class patrol boat, the Joint Offshore Protection Command and the Pilbara Regiment.[30]

United Kingdom

On 27 September 2006, the U.S. Congress was notified by the Defense Security Cooperation Agency that the United Kingdom was seeking to purchase a pair of MQ-9 Reapers. They are operated by No. 39 Squadron RAF out of Creech Air Force Base, Nevada.[31] A third MQ-9 is in the process of being purchased by the RAF.[31]

On 9 November 2007, the UK Ministry of Defence announced that its MQ-9 Reapers had begun operations in Afghanistan against the Taliban.[32] On 4 January 2008 it became public that the United Kingdom wants to purchase a further 10 MQ-9 Reapers, giving the Royal Air Force a total fleet of 13 Reaper UAVs.[33]

In April 2008, British special forces were forced to destroy one of the two Reapers operating in Afghanistan to prevent sensitive material falling into the hands of the Taliban after it crash landed.[34]

[edit] Germany

Germany has made a request to purchase five Reapers and four ground control stations, plus related support material and training. The request, being made through the Foreign Military Sales process, was presented to Congress through the Defense Security Cooperation Agency on 1 August 2008 and is valued at US$205 million.[35][36]


On August 1, 2008, Italy submitted a FMS request through the Defense Security Cooperation Agency for four aircraft, four ground stations and five years of maintenance support, all valued at US$330 million.[35][37]

Operational history
This article may contain an inappropriate mixture of prose and timeline. Please help convert this timeline into prose or, if necessary, a list.

* The California Office of Emergency Services requested NASA support for the Esperanza Fire, and in under 24 hours the General Atomics Altair (NASA variant of the Predator B) was launched on a 16 hour mission to map the perimeter of the fire. The Altair had just returned from a test mission a day before the Esperanza Fire started. The fire mapping research is a joint project with NASA and the US Forest Service.[38][39]
* On 25 April 2006, an MQ-9 operated by U.S. Customs and Border Protection crashed near Nogales, Arizona. The pilot, remotely operating the vehicle from Sierra Vista Municipal Airport, reported a momentary lockup of the displays on the primary control console. The pilot switched control to a secondary console, and in doing so inadvertently shut down the vehicle's engine, causing it to descend out of reach of communications and ultimately crash.[24][40]
* On 1 May 2007, the 432d Wing of the United States Air Force was activated to operate MQ-9 Reaper as well as MQ-1 Predator UAVs at Creech Air Force Base, Nevada. The pilots first flew combat missions in Iraq and Afghanistan in the summer of 2007.[41]

* As of October 2007 the USAF is flying operational missions in Afghanistan.[14] As of 6 March 2008, according to USAF Lieutenant General Gary North, the Reaper has attacked 16 targets in Afghanistan using 500-lb bombs and Hellfire missiles. On 4 February 2008 the Reaper dropped a bomb on a truck carrying an insurgent mortar and team near Kandahar.[42]

* On July 17, 2008, the Air Force began flying Reaper missions within Iraq from Balad Air Base.[43][44]

Here is a fix for those who want to use the skin with the new Trade Update. I know this doesn't look perfect, but it's better than having a broken friends list.

Navigate to "Steam\skins\MetroTwit"

Delete or rename the "Friends" folder

I'd love to update the theme, but juggling school amongst other things leaves me with less time than I'd like to complete projects. So until I find the proper files for the new friends list and the time necessary to re-skin it, this'll have to do.

Version 1.0 released!

This is a Steam theme I'm working on based on the gorgeous Twitter client, MetroTwit, with permission from Long Zheng.

I created this DVD sleeve for the Black Mesa modification (A remake of Half-Life on the Source engine.) This is a custom design I personally came up with.

If you would like to host it somewhere else, just please tell me where and give me credit! Don't rip!
I must have spent at least 12-13 hours total on this and Id like to not regret releasing this to the public.

That being said, please enjoy. Its high-res so it should look great when you print it out.
I don't know the exact printing dimensions at the moment, but it should fit a standard case just fine.

The Messerschmitt Me 262 Schwalbe ("Swallow") was the world's first operational jet-powered fighter aircraft.[4] It was produced in World War II and saw action starting in 1944 as a multi-role fighter/bomber/reconnaissance/interceptor warplane for the Luftwaffe. Allied pilots referred to it as the "Blow Job".[5] The Me 262 had a negligible impact on the course of the war due to its late introduction, with 509 claimed Allied kills[6] (although higher claims are sometimes made[Notes 1]) against the loss of about 100 Me 262s.

Design and development
Hans Guido Mutke's Me 262A on display at the Deutsches Museum

The Me 262 was already being developed as Projekt P.1065 before the start of World War II. Plans were first drawn up in April 1939, and the original design was very similar to the plane that eventually entered service. The progression of the original design into service was delayed greatly by technical issues involving the new jet engines. Funding for the jet program was also initially lacking, as many high-ranking officials thought the war could easily be won with conventional aircraft. Among those was Hermann Göring, head of the Luftwaffe, who cut back the engine development program to just 35 engineers in February 1940; Willy Messerschmitt, who desired to maintain mass production of the Bf 109 and the projected Me 209; and Major General Adolf Galland, who supported Messerschmitt through the early development years, until flying the Me 262 himself on 22 April 1943. By that time, problems with engine development had slowed production of the aircraft considerably.[8]

In mid-1943, Adolf Hitler envisioned the Me 262 not as a defensive interceptor, but as an offensive ground-attack/bomber, almost as a very high speed, light payload Schnellbomber ("Fast Bomber"), to penetrate Allied air superiority during the expected invasion of France. His edict resulted in the development of (and concentration on) the Sturmvogel variant. It is debatable to what extent Hitler's interference extended the delay in bringing the Schwalbe into operation.[9][10] Albert Speer, then Minister of Armaments and War Production, claims in his memoirs, that Hitler originally blocked mass production of the Me 262, before agreeing to their production in early 1944. However he rejected arguments that the plane would be more effective as a fighter against Allied bombers which were then destroying large parts of Germany and wanted it as a bomber with which to use for revenge attacks. According to Speer, Hitler had felt that its superior speed compared to other fighters of the era meant that it couldn't be attacked. Based on such reasoning, Hitler had preferred it for high altitude straight flying and hence his initial preference for it to be a long range bomber. [11]

Although it is often stated the Me 262 is a "swept wing" design, the production Me 262 had a leading edge sweep of only 18.5°. This was done primarily to properly position the center of lift relative to the centre of mass and not for the aerodynamic benefit of increasing the critical Mach number of the wing. The sweep was too slight to achieve any significant advantage.[12] This happened after the initial design of the aircraft, when the engines proved to be heavier than originally expected. On 1 March 1940, instead of moving the wing forward on its mount, the outer wing was positioned slightly backwards to the same end. The trailing edge of the middle section of the wing remained unswept.[13]. Based on data from the AVA Göttingen and windtunnel results, the middle section's leading edge was later swept to the same angle as the outer panels.[14]

The first test flights began on 18 April 1941, with the Me 262 V1 example, bearing its Stammkennzeichen radio code letters of PC+UA, but since its intended BMW 003 turbojets were not ready for fitting, a conventional Junkers Jumo 210 engine was mounted in the V1 prototype's nose, driving a propeller, to test the Me 262 V1 airframe. When the BMW 003 engines were finally installed, the Jumo was retained for safety, which proved wise as both 003s failed during the first flight and the pilot had to land using the nose mounted engine alone.[1]
Messerschmitt Me 262 Schwalbe

The V3 third prototype airframe, with the code PC+UC, became a true "jet" when it flew on 18 July 1942 in Leipheim near Günzburg, Germany, piloted by Fritz Wendel. This was almost nine months ahead of the British Gloster Meteor's first flight on 5 March 1943. The conventional gear, forcing a tail-down attitude on the ground, of the Me 262 V3 caused its jet exhaust to deflect off the runway, with the wing's turbulence negating the effects of the elevators in the tail-down attitude, and the first attempt was cut short. On the second attempt, Wendel solved the problem by tapping the aircraft's brakes at takeoff speed, lifting the horizontal tail above and out of the wing's turbulence.[15]

The aircraft was originally designed with a tailwheel undercarriage and the first four prototypes (Me 262 V1-V4) were built with this configuration, but it was discovered on an early test run that the engines and wings "blanked" the stabilizers, giving almost no control on the ground, as well as serious runway surface damage from the hot jet exhaust. Changing to a tricycle undercarriage arrangement, initially a fixed undercarriage on the "V5" fifth prototype, then fully retractable on the sixth (V6, with Stammkennzeichen code VI+AA) and succeeding aircraft, corrected this problem.

The BMW 003 jet engines, which were proving unreliable, were replaced by the newly available Junkers Jumo 004. Test flights continued over the next year, but the engines continued to be unreliable. Airframe modifications were complete by 1942, but hampered by the lack of engines, serial production did not begin until 1944. This delay in engine availability was in part due to the shortage of strategic materials, especially metals and alloys able to handle the extreme temperatures produced by the jet engine. Even when the engines were completed, they had an expected operational lifetime of approximately 50 continuous flight hours; in fact, most 004s lasted just 12 hours, even with adequate maintenance. A pilot familiar with the Me 262 and its engines could expect approximately 20–25 hours of life from the 004s. Changing a 004 engine was intended to require three hours, but this typically took eight to nine due to poorly made parts and inadequate training of ground crews.

Turbojet engines have less thrust at low speed than propellers, and as a result, low-speed acceleration is relatively poor. It was more noticeable for the Me 262 as early jet engines (before the invention of afterburners) responded slowly to throttle changes. The introduction of a primitive autothrottle late in the war only helped slightly. Conversely, the higher power of jet engines at higher speeds meant the Me 262 enjoyed a much higher rate of climb. Used tactically, this gave the jet fighter an even greater speed advantage in climb rate than level flight at top speed.

With one engine out, the Me 262 still flew well, with speeds of 450-500 km/h (280-310 mph), but pilots were warned never to fly slower than 300 km/h (190 mph) on one engine, as the asymmetrical thrust would cause serious problems.

Operationally, the Me 262 had an endurance of 60 to 90 minutes.

[edit] Operational history
Me 262 A-1a

In April 1944, Erprobungskommando 262 was formed at Lechfeld in Bavaria as a test unit (Jäger Erprobungskommando Thierfelder)[3] to introduce the 262 into service and train a core of pilots to fly it. On 26 July 1944, Leutnant Alfred Schreiber with the 262 A-1a W.Nr. 130 017 damaged a Mosquito reconnaissance aircraft of No. 540 Squadron RAF PR Squadron, which was allegedly lost in a crash landing upon landing at an air base in Italy.[16] Other sources state the aircraft was damaged during evasive manoeuvres and escaped.[17] It was the first victory for a turbojet fighter aircraft in aviation history.[18] Major Walter Nowotny was assigned as commander after the death of Werner Thierfelder in July 1944, and the unit redesignated Kommando Nowotny. Essentially a trials and development unit, it holds the distinction of having mounted the world's first jet fighter operations. Trials continued slowly, with initial operational missions against the Allies in August 1944 allegedly downing 19 Allied aircraft for six Me 262s lost, although these claims have never been verified by cross-checking with USAAF records. The RAF Museum holds no intelligence reports of RAF aircraft engaging in combat with Me 262s in August, although there is a report of an unarmed encounter between an Me 262 and a Mosquito.[19] Despite orders to stay grounded, Nowotny chose to fly a mission against an enemy formation. After an engine failure, he was shot down and killed on 8 November 1944 by First Lieutenant Edward "Buddy" Haydon of the 357th Fighter Group, USAAF and Captain Ernest "Feeb" Fiebelkorn of the 20th Fighter Group, USAAF.[citation needed] The Kommando was then withdrawn for further training and a revision of combat tactics to optimise the 262's strengths.
Me 262 A, circa 1944/45

By January 1945, Jagdgeschwader 7 (JG 7) had been formed as a pure jet fighter unit, although it would be several weeks before it was operational. In the meantime, a bomber unit — I Gruppe, Kampfgeschwader 54 (KG 54) — had re-equipped with the Me 262 A-2a fighter-bomber for use in a ground-attack role. However, the unit lost 12 jets in action in two weeks for minimal returns.

Jagdverband 44 (JV 44) was another Me 262 fighter unit formed in February, by Lieutenant General Adolf Galland, who had recently been dismissed as Inspector of Fighters. Galland was able to draw into the unit many of the most experienced and decorated Luftwaffe fighter pilots from other units grounded by lack of fuel.

During March, Me 262 fighter units were able, for the first time, to mount large scale attacks on Allied bomber formations. On 18 March 1945, 37 Me 262s of JG 7 intercepted a force of 1,221 bombers and 632 escorting fighters. They shot down 12 bombers and one fighter for the loss of three Me 262s. Although a 4:1 ratio was exactly what the Luftwaffe would have needed to make an impact on the war, the absolute scale of their success was minor, as it represented only one per cent of the attacking force. In 1943 and early 1944, the USAAF had been able to keep up offensive operations despite loss ratios of 5% and more, and the few available Me 262s could not inflict sufficient losses to hamper their operations.
Side view of a Me 262 night fighter, note the radar antenna on the nose and second seat for a radar operator.

Several two-seat trainer variants of the Me 262, the Me 262 B-1a, had been adapted as night fighters, complete with on-board FuG 218 Neptun radar and Hirschgeweih ("stag's antlers") antenna, as the B-1a/U1 version. Serving with 10 Staffel, Nachtjagdgeschwader 11, near Berlin, these few aircraft (alongside several single-seat examples) accounted for most of the 13 Mosquitoes lost over Berlin in the first three months of 1945. However, actual intercepts were generally or entirely made using Wilde Sau methods, rather than AI radar-controlled interception. As the two-seat trainer was largely unavailable, many pilots had to make their first flight in a jet in a single-seater without an instructor.

Despite its deficiencies, the Me 262 clearly signaled the beginning of the end of piston-engined aircraft as effective fighting machines. Once airborne, it could accelerate to speeds well over 800 km/h (500 mph), over 150 km/h (90 mph) faster than any Allied fighter operational in the European Theater of Operations.

The Me 262's top ace[Notes 2] was probably Hauptmann Franz Schall with 17 kills which included six four-engine bombers and ten P-51 Mustang fighters, although night fighter ace Oberleutnant Kurt Welter claimed 25 Mosquitos and two four-engine bombers shot down by night and two further Mosquitos by day flying the Me 262. Most of Welter's claimed night kills were achieved in standard radar-less aircraft, even though Welter had tested a prototype Me 262 fitted with FuG 218 Neptun radar. Another candidate for top ace on the aircraft was Oberstleutnant Heinrich Bär, who claimed 16 enemy aircraft while flying the Me 262.

[edit] Anti-bomber tactics

The standard approach against bomber formations, which were travelling at cruise speed, called for the Me 262 to approach the bombers from the rear at a higher altitude, diving in below the bomber's flight level to get additional speed before gaining altitude again and, on reaching the bomber's level, opening fire with its four 30 mm cannon at 600 m (656 yd) range.

Allied bomber gunners found that their electric gun turrets had problems tracking the jets. Target acquisition was difficult because the jets closed into firing range quickly and had to remain in firing position only briefly using their standard attack profile.

Eventually, new combat tactics were developed to counter the Allied bombers' defences. Me 262s equipped with R4M rockets would approach from the side of a bomber formation, where their silhouettes were widest, and while still out of range of the 12.7 mm (.50 in) guns, fire a salvo of these explosive rockets. The explosive power of only one or two of these rockets was capable of downing even the famously rugged B-17; a strike on an enemy aircraft meant its total annihilation.[20] Although this tactic was effective, it came too late to have a real effect on the war. This method of attacking bombers became the standard until the invention and mass deployment of guided missiles. Some nicknamed this tactic the "Luftwaffe's Wolf Pack", as the fighters would often make runs in groups of two or three, fire their rockets, then return to base.

On 1 September 1944, USAAF General Carl Spaatz expressed the fear that if greater numbers of German jets appeared, they could inflict losses heavy enough to force cancellation of the Allied daylight bombing offensive.

[edit] Counter-jet tactics

Tactics against the Me 262 developed quickly despite its great speed advantage. Allied escort fighters would fly high above the bombers — diving from this height gave them extra speed, thus reducing the speed difference. The Me 262 was less maneuverable than the Mustang and trained Allied pilots could catch up to a turning Me 262, though the only reliable way of dealing with the jets, as with the even faster Me 163 Komet rocket fighters, was to attack them on the ground and during take off and landing. Luftwaffe airfields that were identified as jet bases were frequently bombed by medium bombers, and Allied fighters patrolled over the fields to attack jets trying to land. The Luftwaffe countered by installing flak alleys along the approach lines in order to protect the Me 262s from the ground and providing top cover with conventional fighters during takeoff and landing. Nevertheless, in March-April 1945, Allied fighter patrol patterns over Me 262 airfields resulted in numerous losses of jets and serious attrition of the force.

Another experimental tactic was installing nitrous oxide injection, much like the Germans' own GM-1 system, into Mustangs. When chasing an Me 262, the pilot could press a button injecting nitrous oxide into the engine, producing a quick burst of speed.

Other Allied fighters that encountered the Me 262 included the British Supermarine Spitfire, Hawker Tempest and the Soviet Lavochkin La-7. The first recorded Allied destruction of a Me 262, belonging to the unit known as Kommando Schenk, was on 28 August 1944, claimed as destroyed by 78th FG pilots Major Joseph Myers and Second Lieutenant Manford O. Croy flying P-47 Thunderbolts. Oberfeldwebel Hieronymus "Ronny" Lauer of I KG(J) 51, on a landing pattern crash landed his 262 to get away from the Allied fighters, which then destroyed the Me 262 in strafing attacks.[21][22] The first Me 262 , belonging to 3. Staffel/Kampfgeschwader 51, with unit code letters "9K+BL", was shot down in combat on 5 October 1944 by Spitfire IXs of 401 RCAF. The 262 pilot was H.C. Butmann in WNr 170093 of 3./KG51. The Lavochkin was the only Soviet fighter to shoot down a German jet, with La-7 ace Ivan Nikitovich Kozhedub, downing an Me 262 on 15 February 1945 over eastern Germany.

[edit] High speed research
Me 262 interior

Willy Messerschmitt regarded the Me 262 as only an interim type when it went into production.

Swept wings had been proposed as early as 1935 by Adolf Busemann, and Messerschmitt had researched the topic from 1940. In April 1941, he proposed fitting a 35° swept wing (Pfeilflügel II, literally "arrow wing II") to the Me 262,[23] the same wing sweep angle that would later be used on both the American F-86 Sabre and Soviet MiG-15 fighter jets. Though this was not implemented, he continued with the projected HG II and HG III (Hochgeschwindigkeit, "high speed") derivatives in 1944, which were designed with a 35° and 45° wing sweep, respectively.[24]

Interest in high-speed flight, which led him to initiate work on swept wings starting in 1940, is evident from the advanced developments Messerschmitt had on his drawing board in 1944. While the Me 262 HG I actually flight tested in 1944 had only small changes compared to combat aircraft, most notably a low-profile canopy (tried as the Rennkabine (literally "racing cabin") on the Me 262 V9 prototype for a short time) to reduce drag, the HG II and HG III designs were far more radical. The projected HG II combined the low-drag canopy with a 35° wing sweep and a butterfly tail. The HG III had a conventional tail, but a 45° wing sweep and turbines embedded in the wing roots.[25]

Messerschmitt also conducted a series of flight tests with the series production Me 262. In dive tests, it was determined that the Me 262 went out of control in a dive at Mach 0.86, and that higher Mach numbers would lead to a nose-down trim that could not be countered by the pilot. The resulting steepening of the dive would lead to even higher speeds and disintegration of the airframe due to excessive negative g loads.

The HG series of Me 262 derivatives was estimated to be capable of reaching transonic Mach numbers in level flight, with the top speed of the HG III being projected as Mach 0.96 at 6,000 m (19,690 ft) altitude. Despite the necessity to gain experience in high-speed flight for the HG II and III designs, Messerschmitt undertook no attempts to exceed the Mach 0.86 limit for the Me 262.

After the war, the Royal Aircraft Establishment, at that time one of the leading institutions in high-speed research, re-tested the Me 262 to help with British attempts at exceeding Mach 1. The RAE achieved speeds of up to Mach 0.84 and confirmed the results from the Messerschmitt dive tests. Similar tests were run by the Soviets. No attempts were made to exceed the Mach limit established by Messerschmitt.

After Willy Messerschmitt's death, the former Me 262 pilot Hans Guido Mutke claimed to be the first person to exceed Mach 1, on 9 April 1945 in a Me 262 in a "straight-down" 90° dive. This claim is disputed because it is only based on Mutke's memory of the incident, which recalls effects other Me 262 pilots observed below the speed of sound at high indicated airspeed, but with no altitude reading required to determine the actual speed. Furthermore, the pitot tube used to measure airspeed in aircraft can give falsely elevated readings as the pressure builds up inside the tube at high speeds. Finally, the Me 262 wing had only a slight sweep incorporated for trim (center of gravity) reasons and likely would have suffered structural failure due to divergence at high transonic speeds. One airframe (Me 262 HG1 V9, Werknummer 130 004, with Stammkennzeichen of VI+AD) [26]) was prepared with the low-profile Rennkabine racing canopy and may have achieved an unofficial record speed of 975 km/h (606 mph), altitude unspecified.[27]

[edit] Production
Underground manufacture of Me 262s

While Germany was bombed intensively, production of the Me 262 was dispersed into low-profile production facilities, sometimes little more than clearings in the forests of Germany and occupied nations. Through the end of February to the end of March 1945, approximately 60 Me 262s were destroyed in attacks on Obertraubling and 30 at Leipheim[28] (the Neuberg jet plant was bombed on 19 March.)[29] Large, heavily protected underground factories were constructed to take up production of the Me 262, safe from bomb attacks, but the war ended before they could be completed. At B8 Bergkristall-Esche II at St. Georgen/Gusen, Austria, forced labourers of Concentration Camp Gusen II produced fully equipped fuselages for the Me 262 at a monthly rate of 450 units on large assembly lines from early 1945.[30] Wings for the Me 262 were produced in Germany's oldest motorway tunnel at Engelberg to the west of Stuttgart. In the end, slightly over 1,400 Me 262s of all versions were produced. As few as 200 Me 262s made it to combat units due to fuel shortages, pilot shortages, and the lack of airfields that could support the Me 262.[citation needed]

[edit] Postwar history and flyable reproductions
Reproduction of a Messerschmitt Me 262 at the Berlin Air Show 2006

After the end of the war, the Me 262 and other advanced German technologies were quickly swept up by the Americans (as part of the USAAF's Operation Lusty), British, and Soviets. Many Me 262s were found in readily-repairable condition and were confiscated.

During testing, the Me 262 was found to have advantages over the early models of the Gloster Meteor. It was faster, had better cockpit visibility to the sides and rear (mostly due to the canopy frame and the discoloration caused by the plastics used in the Meteor's construction), and was a superior gun platform, as the early Meteors had a tendency to snake at high speed and exhibited "weak" aileron response.[31] The Me 262 did have a shorter combat range than the Meteor.

The USAAF compared the P-80 Shooting Star and Me 262 concluding, "Despite a difference in gross weight of nearly 907 kg (2,000 lb), the Me 262 was superior to the P-80 in acceleration, speed and approximately the same in climb performance. The Me 262 apparently has a higher critical Mach number, from a drag standpoint, than any current Army Air Force fighter."[32] The Army Air Force also tested an example of the Me 262A-1a/U3 (US flight evaluation serial FE-4012), an unarmed photoreconnaissance version, which was fitted with a fighter nose and given an overall smooth finish. It was used for performance comparisons against the P-80. During testing between May and August 1946, the aircraft completed eight flights, lasting four hours and 40 minutes. Testing was discontinued after four engine changes were required during the course of the tests, culminating in two single-engine landings.[33]

These aircraft were extensively studied, aiding development of early U.S. and Soviet jet fighters. The F-86 Sabre, designed by the engineer Edgar Schmued, used the Me 262 airfoil (Messerschmitt Wing A) and a slat design similar to that of the Me 262.[34]

The Czechoslovak aircraft industry continued to produce single-seater (designated Avia S-92) and two-seater (designated Avia CS-92) variants of the Me 262 after World War II. From August 1946, a total of nine single-seater S-92 and three two-seater CS-92 planes were completed and test flown. They were introduced in 1947 and in 1950 they were supplied to the 5th Fighter Squadron. These were kept flying as late as 1957. They were the first jet fighters to serve in the Czechoslovak Air Force. Both versions are on display at the Prague Aero museum in Kbely.

In January 2003, the American Me 262 Project completed flight testing to allow for delivery of near-exact reproductions of several versions of the Me 262 including at least two B-1c two-seater variants, one A-1c single seater and two "convertibles" that could be switched between the A-1c and B-1c configurations. All are powered by General Electric J85 engines and feature additional safety features, such as upgraded brakes and strengthened landing gear. The "c" suffix refers to the new J-85 powerplant and has been informally assigned with the approval of the Messerschmitt Foundation in Germany (the Werk Number of the reproductions picked up where the last wartime produced Me-262 left off - a continuous airframe serial number run with a 50 year production break). Flight testing of the first newly manufactured Me 262 A-1c (single-seat) variant was completed in August 2005. The first of these machines went to a private owner in the southwestern United States, while the second was delivered to the Messerschmitt Foundation at Manching, Germany. This aircraft conducted a private test flight in late April 2006, and made its public debut in May at the ILA 2006. The new Me 262 flew during the public flight demonstrations.[35] Me 262 Werk Number 501241 was delivered to the Collings Foundation as White 1 of JG 7. This aircraft will be offering ride-along flights starting in 2008. [36]

this thing always seemed kind of ridiculous to me...ever notice that since september 11th it's never moved from yellow?

so i read the dhs memo on right wing extremist the other day. i thought it was a little over blown. i think it's a little suspicious that they would want to label brave men and women who swear an oath to uphold and defend the u.s. constitution as possible security threats.

why would they want to do this? could it be that they know that some of their directives are close to being un-constitutional? could it be they also know that these men and women would, if given an un-constitutional order such as seizing firearms from the american people, would not obey and possibly resist therefore becoming a national security threat in the eyes of the dhs?

anyway, i was thinking about this when i made my call to the dhs office. i told them that my neighbor had a ron paul sticker as well as an iraq veteran sticker on his car. i told the guy that i had read the dhs report on right wing extremist and was needing to know what to do. you will not believe what he suggested i do....he told me that if i was concerned i needed to call my local fbi office and make a report! i could not believe it! i swear, sometimes i do not know where i am living!

here's a link [link] to the real dhs advisory system.

The Hobnobbers, a.k.a. the founders of the noble and royal houses of the Andali Confederation, plotting their break for independence from the European Union with a Spartan Group mercenary commander. An excerpt from the Dark Nova RPG history files, written by Cap'n Sally-

The second war came in 2280 as the Andali Confederation made a big comeback. The whole thing started with an elitist country club debate in 2267, I shit you not. The heads of a dozen wealthy and powerful industrial families were hobnobbing one day, and the discussion turned to a mixture of politics and history. Turns out that each of them could trace their roots to one noble family or another in old Europe, and they began a big ol’ debate about how much better things were during the Renaissance, blah blah blah. One thing leads to another, and the discussion slowly evolved into a plan for restructuring the colonies. Public sentiment towards the European Union hadn’t improved much since the Andali systems were conquered, and even the wealthy wanted a change in leadership at the very least. The hobnobbers were, being wealthy elites, well-versed in classical literature, including the works of Nicolò Machiavelli. Using Machiavelli’s The Prince as a blueprint, the hobnobbers (I love that word) cooked up a three-part plan. The first part was a viral propaganda and public relations campaign to remind the people what the European forces had done, to point out the freedoms experienced by those colonies that had succeeded in their bids for freedom, and fomenting pure, unadulterated hatred for the EU. The second part was to create a mythology of noble houses of ancient European origins, dethroned by the evil fascist and socialist governments that had come to power throughout the 20th and 21st Centuries, who were the true leaders of the people. This mythology centered, of course, on the very same families the hobnobbers came from. The third part was the quiet financing of a sizeable private army by each of the hobnobbers through their corporate and industrial assets.
Contracting non-European mercenary firms to provide security for their industrial facilities, they started recruiting thousands of idealistic Andali youths who had bought into the mythology, and had the merc firms arm and train them for combat. The mercs figured out what was going to go down, but didn’t say jack because, frankly, they realized a free Andali nation would owe them, and be likely to prove a very lucrative client in the future. Ah, war as business, gotta love it. At least it’s honest.
Thirteen years after the initial hobnobbing session, the plan kicked off. Contract mercenary fleets- Spartan Group, Venturi Military Solutions, and many Ahrugan mercenaries with their own ships- combined with tens of thousands of nationalist troops loyal to each of the “noble” houses in a joint operation. In lightning strikes the Andali ground forces took out the command and control centers and government administration buildings on each colony world. Simultaneously, mercenary SpecOps units hit and disabled the primary European garrison with a non-lethal bioweapon slipped into their drinking water that gave the soldiers crippling gastroenteritis. This literal shit storm disorganized the European troops long enough for the Andali soldiers to overrun them. With the colonial garrisons taken down, the Andali commanders immediately set about prepping to defend against the inevitable European counterattack. They pulled the mercenaries back to defend the colony worlds and stations, and burped out a bunch of etheric emulator satellites. Why, you might ask, were they throwing Omninet VR emulators out into space? Ah, grasshopper, you have to understand the European approach to warfare.
Not since the Americans during the last half of the 20th and first part of the 21st Centuries had a nation existed that was more casualty-adverse. Dead soldiers and sailors made for bad press back home, and the casualty-adverse mindset led to an unbelievably unhealthy level of reliance on drones. Ground combat was fought with combat robots, fighter drones launched from control carriers where the pilots were safely tucked away in the bowels of the ship, and so on. The Andali planners knew this, and as the European fleets jumped into the dozens of Andali systems to crush the “upstart rebellion”, they unleashed their secret weapon- netjackers.
As the drones were launched, thousands of netjackers hacked their command sequences or hijacked their pilot feeds, disabling the drones or sending them back against their own carriers. Aboard the dropships and troop transports, combat robots suddenly activated and shot the bat crap out of the vessels from within, destroying them. It was an utter disaster for the EU. Now, for my part, the sight of several drones drunkenly spiraling into their carriers like sauced kamikazes was funny as hell, but European Fleet Command didn’t see it that way. The EU followed up a few days later with real warships and real, meat-body troops. The Andalis were waiting for this, and in a truly Machiavellian move, sent what could only be described as modern-day “fire ships” (if you don’t know what a fire ship is, research the Spanish Armada vs. Sir Francis Drake back in the 16th Century) when they launched shuttles loaded to the gills with radioactive waste and other special ingredients. Thinking the shuttles were nuclear suicide bombs, the EU ships blew the batsnot out of them, creating a massive radioactive debris field. Said debris field just happened to screw up the EU ships’ sensors enough to hide the signature of the barrage of incoming MAC rounds launched from mass drivers on the planets’ surfaces. Normally, MAC rounds traveling that far- between three and ten light seconds distance- would be pinged by gravitic sensors, allowing the ships to fire countermeasures or evade. Not with a big-ass radioactive debris fields and a few gravity lens generators thrown in for flavor.
The European ships were taking significant damage and still hadn’t closed to firing range of the planets and their defense fleets. Making matters worse, the Andalis were using gravity lenses to curve the trajectories of their MAC shots, banking rounds in wide arcs around behind the fleet, confusing the EU fleet commanders as they were shot from behind, but no ships were present.
Three of the fleets bugged out, withdrawing to friendly systems to regroup and recover. The rest followed standard protocol and pulled into tight defensive formations to allow their shields to overlap, creating a shield wall against the incoming rounds. It was quite effective, and the MAC rounds went from devastating withering fire to harassment attacks as the EU ships were able to transfer all of their shield output to the outermost facing side. Unfortunately, it also allowed the Andalis to pinpoint the fleets’ exact locations and short-jump automated freighters right on top of them. Those ships not destroyed by the tidal forces of the jump points were smashed or scattered by the impact of hypervelocity cargo ships, the reactors of most of which went critical upon impact, doing even more damage. Andali Confederation 2, European Union 0.
The Andalis managed to overrun and capture the surviving ships easily, and added them to their growing fleet of warships. The EU were shocked at the losses they had suffered, and withheld further attacks until they could formulate a plan. Taking a cue from the Ahruga, they decided to try an overkill approach, sending six carrier task-forces to each star system. This constituted nearly twenty percent of the entire European fleet at the time. Knowing that they’d lost the element of surprise, and not wanting to be thought of as one-trick ponies, the Andali planners had already come up with phase two of their operations. Standard military operational protocol back then was to jump a scout ship into the Oort cloud of a target system, cloak it, and slowly work its way into the inner system to the target planets over a week’s time. The scout ship would then gather intelligence, report back to the main fleet, and give precise jump coordinates for the ships to pop into close orbit and come out swinging. The Andalis knew this, and set up listening posts on comets in the Oort cloud to detect the jump points of incoming ships (yeah, I know, common-freakin’-sense, but that tactic was new back then.) As soon as the scouts would pop in, the Andalis set up their defenses in such a way as to leave subtle, yet potent weaknesses that could be detected by a sound strategic mind. Sure enough, the scout ships came, scanned, and jumped back out over the next several weeks. As soon as the scouts left, however, the Andalis set up ambushes at the likely jump points.
Soon enough, the European assault began, and the majority of the incoming fleets found themselves in a world of hurt of gravity and fusion mines, killing-field volley fire, and missile barrages from orbital defense platforms that hadn’t been there in the intelligence briefs, as well as planetary defense cannons the rebels weren’t even supposed to have (thanks to Ahruga-Mart, selling big guns to anyone the Europeans don’t like since 2267!) Both sides took heavy losses, but the Europeans were forced to retreat once again. Back home, the war had become incredibly unpopular as Andali-leaked footage of the battles coincided with tens of thousands of next-of-kin notifications. Masters of propaganda, the hobnobbers amped up the people, and solidified their positions as neo-royalty, noble houses ruling a confederation of systems. By the end of 2281, the European Union found itself bogged down in a guerrilla war against what was rapidly becoming a solidified nation. The death-knell to the war came in 2282 when the Australio-Pacifica Coalition and Ahrugan Tribal Confederation officially recognized the Andali Confederation as a sovereign, self-governing state. Having had no decisive victories, and facing a brutal insurgency and possible intervention by the APC and ATC, the European Union signed peace accords and formally recognized the Andali Confederation as well. The EU didn’t go quietly, however, and they still to this day lend material and financial support to various “loyalist” insurgency groups and separatist movements within the AC. Not openly, of course, but everyone knows they are behind it. The bickering between the AC and EU in the TAN council is as heated today as it was back then, so if you ever want to get an insight into the Andali Revolution, pop on CBN and watch the council debates.
