The Delta-class DX-9 Stormtrooper Transport Flight is a 20-meter long troop transport unit that consists of four Delta-class DX-9 Stormtrooper Transport, along with four pilots, eight gunners, four technicians, and two mechanics to operate and maintain them. Designed for the Galactic Empire as a well armed and shielded troop transport and assault craft, specifically to carry stormtroopers on missions to board and capture enemy ships or stations. It is well armed with eight forward-facing laser cannons and four ion cannons, in addition to two torpedo launchers that provided attacks only in a forward arc. Hyperdrive capable, this vessel has average maneuverability, speed, armor and shielding. Operated by the pilots in the flight, each can carry up to 30 stormtroopers allowing the flight to carry 120 soldiers or passengers. It was used extensively by the Galactic Empire for boarding actions against hostile targets, though it saw less use if any heavy opposition was expected with further improvements in later ATR-6 and ETR-3 designs.
