From Wikipedia:
The X-Wing Fighter was a prototype for a hyperdrive-capable, long range, single-seat interceptor aircraft for space battle for the United States Army Air Corps. The X-wing carried four laser cannons, along with dual launch tubes for proton torpedoes. Other warheads, such as concussion missiles, could be fitted as an alternative secondary weapon. The starfighter was used in the Pacific Theater of World War II, specifically during the battle of Midway and other smaller engagements. Although the design was conceptually advanced, it was beset by numerous problems and never approached its anticipated level of performance. The project was canceled after the sole completed prototype was destroyed by an engine fire.
