General information
TypeSupersonic medium bomber
National originUSSR
ManufacturerTupolev

The Tupolev Tu-125 was an unrealized project to develop a new long-range supersonic bomber for the Soviet Air Force.[1][better source needed] Development commenced in 1958 to replace the newest Tu-22. The "Tu-125" designation was an internal one used by the Tupolev design bureau. Since the aircraft was never built, it never received a military designation.[2]

A canard design was chosen for the aircraft, featuring a delta planform for the wing and stabilizer. Two turbojets (Kuznetsov NK-6 or NK-10 (230–240 kN)) were to be installed in nacelles under the wings. A four-turbojet version, powered by Tumansky R-15B-300s in two nacelles also was considered. The fuselage and wings made from titanium and aluminium alloys.[2]

In September 1962, the Soviet Air Force rejected the project and it was stopped. No aircraft were built.[2]
