Prototypes of a new U.S. fighter YF-23, lost USAF bid to the Lockheed Martin F-22 Raptor.
Fighter aircraft are small airplanes that are made to fight other airplanes. They are often fast, having aerodynamic shapes (shapes that make them move through air easily) and very powerful engines for their size. They also usually are maneuverable (turn well). Fighters can carry many different kinds of weapons, including missiles, machine guns, and bombs. While fighters may be used to attack vehicles, soldiers, or buildings on the ground, they are different from bombers because they are usually designed to attack other airplanes.
