I really have a hard time looking at the Chimera as anything other then a Escort, doesn't have any more hull then some of the other Fleet Escorts (Fleet Patrol, Steamroller, Fleet Advanced, etc). I would classify the Defiant actually a Destroyer, because technically speaking Destroyers are Destroyer Escorts, that escort Battleships and Carriers.
Funny thing about the Chimera, its special abilities do not rely on maneuverability. If you up the hull, lower its turn, it would be just as effective as a tank, especially with that universal Lt.Cmr. slot. In fact, design wise, it makes more sense as Light Cruiser.
