The first aircraft designed as a jet fighter, and also the first twin-engined jet aircraft, was the German Heinkel He 280. The first prototype, the 280V-1, was first flown on 2 April 1941 powered by two Heinkel HeS 8 turbojets, each developing approximately 1102 1b static thrust. Maximum level speed of the He 280V-5, with HeS 8A engines of 1650 lb static thrust, was demonstrated to be 510 mph at 19 680 ft. It did not achieve production status, being abandoned in favor of the Messerschmitt Me 262.
