A fighter aircraft is a military aircraft designed primarily for air to air combat against other aircraft, as opposed to bombers and attack aircraft, whose main mission is to attack ground targets. The hallmarks of a fighter are its speed, maneuverability, and small size relative to other combat aircraft.
Fighter jets are aircraft used by militaries around the world for in air combat. Fighter airplanes were initially used during World War I but were powered by piston engines. Piston engines work by pistons moving back and forth within cylinders. Fuel entering the cylinders is ignited and the expansion of hot gases causes the crankshaft to turn, and the propellers to rotate, which thrusts the plane forward. A jet engine, however, uses direct thrust. Jet engines work by pulling air through a fan at the front. The air is compressed and combined with fuel which creates a spark.
