Federation Ship Classes

[TNZ]

One of the biggest problems with the Federation ship classes is that a larger size does not mean better combat performance. Examples of this are the Galaxy and Sovereign classes. The Galaxy ships are bigger but Sovereign class ships have twice as much space devoted to weapons than Galaxy class ships do. So, for the purposes of the STM, Sovereign class ships should be considered larger than Galaxy class ships.
