Okay, I couldn't sleep, so I decided to finish the next model.
_ Imperial Civil Engineering Escort Frigate, 'Ke'vak' and 'Sublime' Types_
Long Range Escort Ship, Axe-tail Imperial Ministry of Justice
Imperial Civil Engineering builds the 'Ke'vak' Type Escort Frigate primarily for the Imperial Ministry of Justice. An integrated wide-field cloaking device enables it to hide ships in formation, making it perfect for such duties as witness protection and escort duty. It is armed with proton burst weapons and Slaughter missiles, with autocannons for defense. Fitting all this equipment into such a small hull, however, severely reduces the available room for modification.
The Imperial Martial Engineering 'Sublime' Type Escort Frigate has only been in service for a few years, but it is already displacing the 'Ke'vak' Type. In addition to more powerful engines than the 'Ke'vak,' the 'Sublime' has greater range and stronger defenses. The addition of a photon beam to its armament grants the ability to take on much larger vessels, and of course the wide-field cloaking device gives it the ability to conceal allied ships. All these additions, of course, come at a commensurate price; the 'Sublime' Type is half-again as expensive.
It should be noted that the escort frigate is also used by the Axe-tail Imperial Starfleet, albeit rarely. The AIS mainly uses it for covert operations: it's small enough to evade enemy sensor nets, and is fully capable of atmospheric flight (unlike the larger ships).
The only reason I was up until two in the morning working on this was I just plain couldn't sleep.
