The Victory III Class Star Destroyers saw limited production after the battle of Endor. They were vastly simplified to ease construction. However, their simple design did not limit their effectiveness. They were fitted with the newest Heavy Turbolasers mounted in several pairs on extended mounts all over the hull. These Turbolasers were the same type used on Super Star Destroyers, and while they overheated quickly, they could produce short term bursts of firepower equal to an Imperial I class Star Destroyer. They also had improved anti starfighter capabilities.
Very cool ship! I like the bridge, it looks really neat! The greebles on the sides are also great, you used the structure for the UCS Star Destroyer didn't you? Lol, I did the same with mine, yours turned out very nice if I do say so. If you wouldn't mind, can you check out my stuff? I'd really appreciate it!
