America's first jet fighter was so underwhelming it ended up as a trainer
In short: The Bell P-59 Airacomet was the United States' bold entry into the jet age, born from a secret British engine design. Yet, despite its revolutionary propulsion, the aircraft proved sluggish and unstable. It never saw combat, ultimately serving only to teach American pilots how to handle the future of flight.
In 1941, the United States lacked a domestic jet program. To bridge the gap, Major General Henry H. Arnold secured plans and a physical example of the British Power Jets W.1 turbojet. General Electric was contracted to replicate the technology, resulting in the J31 engine. Bell Aircraft was then tasked with building a fighter around this new powerplant, with the project masked under the deceptive P-59A designation to imply it was merely a continuation of a canceled piston-engine fighter.
The resulting P-59 Airacomet was a technological milestone, yet it struggled with the limitations of early turbojet development. Pilots reported poor engine response and significant instability at speeds exceeding 290 mph, causing the aircraft to snake in flight. Combat trials in February 1944 against propeller-driven fighters like the P-38J Lightning and P-47D Thunderbolt proved that the jet was consistently outperformed by its older counterparts. It was also found to be a poor gunnery platform, hampered by insufficient thrust.
The military's initial enthusiasm waned as these performance issues became clear. While 100 production aircraft were originally ordered, the USAAF eventually canceled half of the contract. The 50 completed units—20 P-59As and 30 P-59Bs—were relegated to training roles, helping pilots transition to the handling characteristics of jet aircraft. Even the U.S. Navy, which evaluated two YP-59As, deemed the design entirely unsuitable for carrier operations. Despite its failure as a combat machine, the Airacomet provided essential operational experience that paved the way for more successful successors like the Lockheed P-80 Shooting Star.
The aircraft's legacy is preserved today in several museums, including the National Museum of the United States Air Force and the National Air and Space Museum. One prototype, serial number 42-108777, is currently undergoing restoration to flying condition. While the P-59 never achieved the glory of a frontline fighter, it remains a vital piece of aviation history, marking the moment the United States first stepped into the era of jet-powered flight.
