The Klingon blockade of Cardassia Prime inflicted severe damage to their military infrastructure and therefore their ability to wage war. Even more it injured deeply the fabled and deep-rooted Cardassian pride. Cardassia had always mandated an aggressive expansionist policy but never had a clear vision on how to accomplish it with the use of ships rather than stationary space stations such as Terok Nor. The mobility required to move from system to system was not possible with current Cardassian technology. However, a small and innovative group of Cardassian engineers had been working on designing a massive flagship that could effectively control distant systems and demoralize those who sought to strangle Cardassia's economic growth. But the problem in building this vessel was the lack of organization as much as the available resources, much of which had to be imported.
With the end of the blockade and the start of the Alliance with the Dominion the Cardassian shipyards started construction of what was to be the Hutet Class. Clearly a departure from the traditional Cardassian ship design, its enormous size reflected the ambitious desires of its makers. Described as a planetary assault ship, its primary role was to launch long-term moderate size assaults against moderately defended systems with little or no escort. That a Hutet could do this due to a new structural technology that could absorb hits from of all conventional weapons. In addition an innovative use of Dominion technology allowed the Hutet to quickly perform short term self-repair of battle damaged critical systems. To assist in its role of rebellion suppression the Hutet can maintain support for a detachment of Peltast Class fighters. By far the most frightening weapon on the Hutet is the Focused Wave Cannon, which is mounted on the forward array, which harness enough firepower to decimate entire installations.
Sometimes in life you must ask yourself those important questions; such as 'where is my towel?'
"....a towel has immense psychological value. For some reason, if a strag (strag: nonhitchhiker) discovers that a hitchhiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, washcloth, soap, tin of biscuits, flask, compass, map, ball of string, gnat spray, wet-weather gear, space suit etc., etc. Furthermore, the strag will then happily lend the hitchhiker any of these or a dozen other items that the hitchhiker might accidentally have "lost". What the strag will think is that any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still knows where his towel is, is clearly a man to be reckoned with." - Douglas Adams 'The Hitchhiker's Guide to the Galaxy'
The Cumberland PPR-19 is one of the nastiest close-quarters military weapons ever produced in recent years. This is due to the dual energy format produced- a hybrid between a particle projection weapon and plasma projector. The bolts produced by the PPR-19 are a condensed core of pure plasma surrounded by an EM field, which in turn is surrounded by an outer layer of condensed charged particles within an overall outer EM field shell. In a fashion similar to ancient buckshot weapons, the bolt separates into a broad field of destructive energy about a meter across upon impact.
Coming in 2nd, is the Constellation class Star Cruiser.
The Constellation Star Cruiser was introduced in the mid 2280's as a viable replacement for the aging Constitution class, which was over 40 years old. Increasing production costs and problems with the design caused the Constellation class to never fully replace or supplement the Constitution class as Starfleet's next generation exploration class. That honour would go to other designs.
Update: This is my latest update on this model, included in this update is a new nacelle and fixed window sizes and layout. I also modeled in the hangars rather than them just being textured in.
