The Sa-Matra is the name given to a Precursor Battleship discovered by the Ur-Quan Kzer-Za. It is the very symbol of Ur-Quan dominance; a virtually invincible war machine that guarentees that the Ur-Quan species will never need know fear of anything.
This weapon was employed against the Alliance of Free Stars during their war with the Ur-Quan Kzer-Za and their Hierarchy of Battle Thralls. It quickly broke the Chenjesu/Mmrnmhrm lines, incinerating conventional vessels at far beyond their own weapons ranges, and led directly to their surrender to the Kzer-Za.
Among the Ur-Quan, the word "Sa-Matra" means "Great Trophy", for that is what it is to them. It is the prize given to the race, Ur-Quan Kohr-Ah or Kzer-Za, who wins the Doctrinal Conflict.
Physically the vessel is huge,blue, with claws, spikes and similar sticking out of it. It has alarge core-like sphere in the middle. It´s weapon systems are the dreaded Repulsion Sphere, intellinget homing weapons that send ships flying a long way. The other is ther Plasma Destrustion Totoids, fireballs that track and destroy any ship in seconds.
