The WS-125 was an American super long-range strategic bomber project during the Cold War to develop a nuclear-powered aircraft.
In 1954, the United States Air Force (USAF) issued a weapons system requirement for a nuclear-powered bomber, designated WS-125. In 1956, General Electric teamed up with Convair (X211 program) and Pratt & Whitney with Lockheed in competitive engine/airframe development to address the requirement.[1]
In 1956, the USAF decided that the proposed WS-125 bomber was unfeasible as an operational strategic aircraft. Finally, after spending more than $1 billion, the project was canceled on March 28, 1961.[citation needed]
Two General Electric J87 turbofan engines were successfully powered to nearly full thrust using two shielded reactors. Two experimental engines complete with reactor systems (HTRE-3 and HTRE-1, which was modified and renamed HTRE-2) are located at the EBR-1 facility south of the Idaho National Laboratory 43°30′42.22″N 113°0′18″W / 43.5117278°N 113.00500°W. As of 2022 the reactors are still on display there.[citation needed]
