Defender-class Star Destroyer
As requested by some crazy friends trying to sort out the mess regarding New Republic capital ships.
The Defender-class Star Destroyer (as seen at WotC's site here) is one of the New Republic's most powerful warships, designed to be the ultimate Star Destroyer. As of the Yevethan Crisis only 10 Defenders were in service, though it is safe to assume these formidable destroyers were in production through the NJO era.
There are only two published images of the Defender-class Star Destroyer. I merged elements from the WEG version with the streamlined WotC image, and had some techies critique it. After a complete hull and structural overhaul, this is the final image.
