Koros-Strohna

The Koros-strohna Worldship is a 10 kilometers long transport that can house entire communities of Yuuzhan Vong, providing them with food and shelter. Like all other Yuuzhan Vong vehicles and vessels, the Koros-Strohna or Worldship was made of yorik coral. The Worldship has more in common with a planet than a starship and like most other Yuuzhan Vong bio-engineered vessels, it did not appear to be a starship at all. Its main body is a disc-shaped bulk littered with hundreds of weapon projections and other protrusions. On the edges of the Worldship are several large spiral arms, causing the ship resemble a galaxy. These spiral arms or outrider ganglia were used to dock the worldship's Coralskippers. They can also be used as solar sails to push the worldship through space. Dovin Basals could also be used to propel the worldship by projecting gravity wells to drag Yuuzhan Vong ships through the interstellar void or to strip enemy vessels of their deflector shields.

The Worldship was protected by 200 plasma weapons emplacements. Additional defence came from the worldship's cargo and troop holds which could transport 5,000 warriors along with starfighters and planetary vehicles. Another weapon was the huge, tubular worm called Gorros' Fen which extended from the bowels of the worldship. The Gorros' Fen could be used to deploy troops and to gather nutrients for the worldship to stay alive.
