This is something I blocked out a long time ago: a cruiser/battlecruiser design pair for the Impellor-class carrier. I’m envisioning the carrier as a variant of a full 4.3km dagger ship. The engines are designed to move that ship along at a good pace, but the carrier version cuts away a secondary reactor, about a third of the hull by volume, a good section of superstructure, and a fair chunk of guns, but keeps the engines, which makes the carrier very agile, which is good for a ship that needs to be able to stay out of melee. The combat version retains the main reactor, producing ~5.5x ISD power, and adds (or retains rather) a secondary reactor complex where the forward mandible hangar bays would be for the carrier variant that adds another ~2.5x ISD power. That’s adding up to ~8x ISD power, so roughly 8e25W.
