During the
Cold War the
USSR had an experimental nuclear aircraft program. Without the need to refuel, a
nuclear-powered aircraft would have greatly extended range compared to conventional designs. On 12 August 1955 the
Council of Ministers of the USSR issued a directive ordering bomber-related design bureaus to join forces in researching nuclear aircraft. The design bureaus of
Andrei Tupolev and
Vladimir Myasishchev became the chief design teams, while
N. D. Kuznetsov and
A. M. Lyulka were assigned to develop the engines. They chose to focus on the direct-cycle system from the start, testing ramjets, jet engines and even turboprops. The VVRL-lOO reactor was fitted in the bomb bay of the aircraft, requiring aerodynamic fairings over the top and bottom. From 1961 to 1969, the Tu-95LAL completed over 40 research flights. Most of these were made with the reactor shut down. As in the US, development was curtailed on grounds of cost and environmental concerns. ==Tu-119==
