Executor-class Star Dreadnaught

The Executor-class Star Dreadnaught is one of the most powerful vessels in Imperial history. The most famous of all of these technological terrors is the Executor flagship, commanded by the late Darth Vader. This ship is a force to be reckoned with in any situation, and cannot be brought down with anything less than a concentrated effort from a very large task force. Ion cannons are useless against its massive hull, save the largest planetary batteries. The original Executor design received additional shield generators to avoid the debacle of Endor, along with minor upgrades. Ref note: Stats revised to reflect SW:ITW and other newer sources.
