Shipwomb
this incredibly huge ship was grown by the Yuuzhan Vong to serve as the "birthplace" of a new generation of ships. Larger than the Death Star, the shipwomb was formed from the same yorik coral as other Yuuzhan Vong ships, and was surrounded by a collection of thick protuberences that flared out from the central hull like the arms of a spiral galaxy. Because all Yuuzhan Vong ships were living creatures, they eventually grew old and died. For this reason, the shipwomb was a vitally important part of any long-distance war fleet, such as the one that invaded the known galaxy. The Yuuzhan Vong destroyed the planet Sernpidal in order to "feed" the shipwomb and the "offspring" ships that it would produce, then set up an operation in which several young shipwombs were grown in the remnants of the planet. The first worldship to begin dying was the Baanu Miir, and the Yuuzhan Vong realized that a living shipwomb would allow them to continue their fight against the New Republic. However, Kyp Durron learned of the growing shipwomb, hidden within the remnants of the planet Sernpidal, and convinced Jaina Solo and Rogue Squadron to attack it. He claimed it was a superweapon in order to gain their support, and the combined forces of the Rogues, Kyp's Dozen, and the Ralroos managed to destroy the shipwomb.
