During the battle against the Pirates in SOL, Sigma could not keep up with production of the Standard Corvette starship for the Galactic Federation. The manufacturer decided to cut corners and created the Corvette SE, a slimmed down version of its older sister ship. The success of the Corvette SE turned the tide in the war against the Space Pirates. After the Pirate threat was neutralized, the Galactic Federation retrofitted the remaining Corvette SE starships for resale.
