The Lancer-class Frigate was designed and put into service after the success of Rebel starfighters in destroying the first Death Star. Built with one clear purpose, these frigates can more than hold their own against enemy starfighters.
Imperial Admiral Drez was the first to envision the Lancer-class ships and proposed the creation of a ship to screen enemy starfighters, freeing up larger ships, such as Star Destroyers, to pummel enemies in ship-to-ship combat. With approval from the Imperial Naval Command, Kuat Drive Yards designed and developed the ship.
Unfortunately, the Lancer costs as much as a heavy cruiser, yet it is only suitable for repelling starfighter attacks, limiting its cost-effectiveness. The number of Lancer Frigates in service in the Empire is limited and it has proved impossible to assign these ships to protect every convoy. The Empire has found that these ships are best put to use when attacking enemy starfighter bases, although the opportunities for these types of missions are rare.
The 20 Corellian AG-2G Quad Laser Cannons are specifically calibrated for use against high-speed and maneuverable starfighters. The weapons have superior tracking and targeting capabilities and are mounted on elevated towers to provide an increased field of fire. Each bank of quad lasers is fed by a single power generator.
