A design for a 150mm dual purpose gun for the Kriegsmarine. Designed to go on my H-Class super battleship design when I finally get it done. It is designed to basically be a German equivalent of the US navy's very effective 5 in. 38 caliber mk28 design found on Iowa-Class battleships and other US battleships.

Please feel free to tell me what you think. Look like a realistic design?

FYI, in order to have a dual purpose weapon of the 150mm caliber, u’d need either power rammer or autoloaders. Originally, the 6 inch/152mm rifles of the Cleveland class were supposed to be dual purpose but the gun crews couldn’t load the shells into the breeches due to the shell weight.  It wasn’t until after the war that the U.S. Navy successfully experimented with power rammers did they overcome that problem, along with the autoloading guns of the Worcester class, but at that point, missiles were deemed better and so the power rammers weren’t implemented operationally.

in terms of your design, it looks too much like an American 5 inch mount. At the very least, I suggest stretching out the mount more length wise, and increasing its height slightly more.

How fast is the rate of fire with these 150mm DP guns?

I figured about 10-15 would be feasible with a good crew.  The higher the rate of fire the better AA gun, so I assume any dp gun built by the Germans in the 40's would shoot for at least 10 per min.

Looks good, I like the idea.  Interesting how the KM used a combination of 10.5 cm and 15 cm guns, while USN split the difference with the 5 inch only guns.  Have you heard of the 12.7 cm SK C/41?  The KM was developing it toward the end of the war as their first dual-purpose ship-mounted gun.  It was based on the 12.8 cm FlaK 40.  If you are going for historical accuracy, this may be a better approach since it was already in the works when the war ended.  Fingerz on the Sketchup warehouse has the land-based version of it in a dual mount, you'd just have to design a turret for it or reuse this one.

I think it look's awesome. Accurate also, even to the rivets. Do tell me though, how many of these did the H-Classes have?

The actual H-class designs called for 12 150mm or 15cm guns but they would have been the same design of those found on the Bismarck and other German ships. They were not designed to have a anti-aircraft role as well.

I figured I would design a dual purpose 15cm gun comparable to that of the U.S. Navy's 5 inch gun for the H-Class design I am working on. I'm thinking I will probably put 10 turrets, with a total of 20 guns, 5 on each side grouped in the middle of the ship. If the Germans would have ever developed a large powerful battleship anti-aircraft defenses would have been a top priority. Im going to try and display that in my design.

Actually, when Germany originally put down Plan Z, those battleships *and battlecruisers* still had light AA weaponry because they were designed before anyone realized aircraft would be a major threat.

Yea I realize that I should have clarified this is intended to be a late war design 1944-1945 in a alternate history scenario in which Germany had the need to rebuild and restrengthen its navy to finally finish off Britain and control the North Atlantic. If such a scenario had presented itself then the Germans would surely have learned a lesson from the progress of the war so far and made all efforts to protect their "super battleship" from air attacks.

There will be no Swordfish crippling this beast!!

So, your design is basiclly like what the Japanese did with the Musashi and Yamato: Started off with a lot of Anti-Ship guns and in the end, having a lot of Anti-Air guns.

Yea sorta like that. Lots of armor, lots of anti-air defenses, and very large main guns.

Sounds German to me. Can't wait to see them then.
