The UGI vessel is equipped with a Prototype Derexius Carbide armor; although not pure Derexium it is actually stronger theN ohre derexium. With its heavy plasma weaponry and Ion weapon systems this vessel is considered too dangerous to allow Federation be accessing it only.
The vessels armament is nearly ten times more powerful then standard Federation ships at the time that this ship was built. Its Plasma armament can wipe out entire cities in a single volley. Even with its advanced Ion weaponry this vessel can destroy the shields till it overloads causing the shields to go down and armor takes a hit.
