XP-80

XP-80. The Lockheed Corporation's first operational jet fighter, the XP-80 was a pioneering American aircraft developed during World War II. Designed under immense secrecy by a legendary team led by Clarence "Kelly" Johnson, it was built to counter emerging German jet aircraft like the Messerschmitt Me 262. Although it arrived too late for combat, its revolutionary design and performance laid the foundation for the successful Lockheed P-80 Shooting Star and established Lockheed's Skunk Works as a premier advanced development division.

Development and design

The urgent development of the XP-80 was initiated in 1943 after Allied intelligence reports revealed the advanced state of German jet aircraft. The United States Army Air Forces contracted Lockheed Corporation to produce a prototype, with Clarence "Kelly" Johnson assembling a small engineering team in a temporary facility in Burbank, California. This group, which would later become the famed Skunk Works, designed the aircraft around the de Havilland Halford H.1B turbojet engine, a British design provided under the Lend-Lease program. The airframe featured a sleek, straight-wing design with the engine mounted centrally in the fuselage, fed by side-mounted air intakes, a configuration that became a hallmark of early jet fighters. The entire project, from contract signing to first flight, was completed in a remarkable 143 days, a testament to the innovative and rapid prototyping methods pioneered by Johnson and his team.

Operational history

The first prototype, nicknamed "Lulu-Belle," made its maiden flight on 8 January 1944 at Muroc Army Air Field (later Edwards Air Force Base) with test pilot Milo Burcham at the controls. Flight testing revealed exceptional performance, with the aircraft quickly surpassing 500 mph, significantly faster than contemporary Allied propeller-driven fighters like the North American P-51 Mustang. A second prototype, the XP-80A, was built with a more powerful General Electric I-40 engine (the production version of the General Electric J33). While the XP-80 proved the soundness of the design, it never saw combat in World War II, as the war in Europe concluded before it could be deployed. Its primary operational role became that of a development and test aircraft, paving the way for the production Lockheed P-80 Shooting Star, which entered service with the United States Air Force after the war.

Variants

Only two direct prototype variants of the initial design were constructed. The first was the original XP-80 (serial number 44-83020), powered by the de Havilland H.1B engine. The second was the XP-80A (44-83021), a redesigned airframe built around the larger and more powerful General Electric I-40 turbojet; this aircraft featured a longer fuselage and revised intakes. The success of these prototypes led directly to the pre-production YP-80A and the major production model, the P-80A Shooting Star, which became the United States Air Force's first fully operational jet fighter. Further developments included the reconnaissance RF-80 and the two-seat T-33 Shooting Star trainer, one of the most produced jet aircraft in history.

Survivors

The historic first prototype, the XP-80 "Lulu-Belle," survives today and is part of the permanent collection of the National Air and Space Museum of the Smithsonian Institution. It is currently on public display at the museum's Steven F. Udvar-Hazy Center in Chantilly, Virginia, alongside other landmark aircraft like the Boeing B-29 Superfortress *Enola Gay* and the Space Shuttle Discovery. The aircraft has been restored to represent its original configuration and paint scheme, serving as a tangible artifact of the dawn of the American jet age and the innovative spirit of the Skunk Works.
