Khellian Heavy Warbird

With development beginning on the verge of the Klingon-Romulan War, the Khellian, or 'hunter', is a wartime design, a stripped-down, upgraded version of the Devoras. At 443m long and with a crew of between 775 and 825, the Khellian is a powerful battleship, equipped with a cloaking device and a strong armament; their good sensors, equal or better than Federation ships of their size, served them in good stead fighting Klingon ships that could also cloak. Nonetheless, it failed to fully turn the tide for the Romulans. Post-war refits on the surviving ships will be needed to correct defects due to the suddenness of their introduction.

The Khellian is one of the most powerful combat ships known to the Federation, armed as well as a stock Sunrise-class or an Allupi Kasierin, and just as durable as an Ambassador-class ship, which it slightly outguns. Its sensors are slightly superior to those of an Excelsior-A. Given its size is not that much bigger than the Excelsior and is more than 300kt lighter than the Devoras, the Khellian pays the price for its best-in-class performance by being relatively poorly appointed and having poor endurance compared to Federation ships, no better than a stock Excelsior.

A Khellian was the flagship of Admiral Wenlai in the closing months of the war with the Klingons, launched prematurely from the Romulan yards before their destruction.
