The SF-3A Lancer II Space Fighters were developed to be carried by ARMD-class Space Carriers. Each SF-3A is loaded with a propulsion system manufactured by the OTEC Company, and they were designed with an overemphasis on initial acceleration that was premised entirely on hit-and-run fly-by combat.
Each SF-3A is furnished with a vernier belt at the base of the two large cannons, and high-maneuverability vernier nozzles in the right and left of the rear section of the fuselage.
The propulsion system can enable an SF-3A to have an acceleration that exceeds 10 G. The ultimate attainable velocity an SF-3A can reach is 7 kilometers per second.
On February 7, 2009, the launch day of the SDF-1 Macross, SF-3A Lancer II Space Fighters were launched from the ARMD-01 Space Carrier to engage the Zentradi in battle under orders from Captain Global. The SF-3A Lancer II Space Fighters fired long range missiles which hit a single Thuverl-Salan-class Battleship but they were unable to destroy it. In response, three Thuverl-Salan-class Battleships arrived and used guided beam cannons on the SF-3A Lancer II Space Fighter. Some of the SF-3A Lancer II Space Fighters were able to dodge the beams but some of the SF-3A Lancer II Space Fighters were also destroyed. (SDFM: "Boobytrap")
