Experimental and test jet aircraft Gloster E.28/39 - May 15, 1941 became the first jet engined aircraft to fly in the United Kingdom, and the very first jet aircraft flown by any of the Allies of World War II. Operational jet aircraft Gloster Meteor - First operational Allied fighter jet, entered Service July 27, 1944. De Havilland Vampire - production aircraft entering service in April 1945. United States Experimental and test jet aircraft Northrop XP-79B "Flying Ram" - prototype tested 5 July 1944, project cancelled 1945. XP-81 "Silver Bullet" - Mixed power. Two prototypes built, project cancelled due to poor flight performance and war ended McDonnell XFH-1 Phantom - Prototype of the FH-1 Phantom XP-83 "Airacomet II" - Redesigned P-59 for long-range escort fighter duties. Cancelled after two prototypes. Douglas XBTD-2 Destroyer - Modifed BTD Destroyer, mixed propulsion, two prototypes built. Cancelled due to poor performance. Operational jet aircraft P-59 Airacomet - First USAAF jet to fly, never saw operational service, only 66 built before contract terminated Lockheed P-80 Shooting Star - in early 1945 it became the first operational jet fighter used by the United States Army Air Forces Ryan FR-1 Fireball - US Navy production, mixed prop and jet aircraft, first flew on June 25, 1944. 66 units delivered. Soviet Union Experimental jet aircraft Lavochkin La-150 - Design started in summer of 1945. First flight, September 1946. Built around the Jumo 004 (RD-10) engine. 5 built. Lavochkin La-152 - First flight, October 1946. Modifications of the 150 design. 3 built with various modifications. Sukhoi Su-5 - Combined propeller/thermojet propulsion. 1 built, first flown 6 April 1945. Grounded after loss of piston engine. Sukhoi Su-7-Development of Sukhoi Su-6 with mixed propulsion.

Factory overrun by Soviet forces before test flights could begin. Horten Ho 229 - Flying wing fighter. Horten H.XVIII - an enlargement of the Ho 229's design, to make it a four jet engined bomber capable of reaching America. Junkers Ju 287 - Multi-engine bomber design; proof-of-concept aircraft flying from 16 August 1944; factory and project captured by Soviets before definitive prototype built. Messerschmitt Me P.1101 - experimental aircraft with ground-set variable-sweep wings. ~75% complete at conclusion of war, led to the Bell X-5 US experimental aircraft.
