Alliance vessels

From Gineipaedia, the Legend of Galactic Heroes wiki

Smaller and more utalitarian than their Imperial counterparts, the warships of the Free Planets Alliance were designed with only one thing in mind: killing the enemy. In general, the technology in the FPA was somewhat inferior to that of the Galactic Empire. cannons possessed weaker yields, and various other technologies — sensors, communications, engines — were slightly inferior by comparison. To combat this inherent weakness, FPA warships were models of efficiency. They typically boasted greater quantities of gun emplacements than Imperial vessels of like similar class, and were smaller and cheaper, too. On the battlefield, each ship class on one side was roughly equal in ability to the same ship class on the other.
