The Il-54 was a transonic bomber developed in the USSR in the 1950s. Only two examples were built before the project was abandoned.
The Council of Ministers issued a directive to OKB-115, for a transonic bomber prototype to be submitted for State Acceptance Trials in July 1954. The design of this bomber went through several stages before settling on the final configuration.
The Il-54, as built, had a very thin 45 degree swept wing with anhedral, which was shoulder-mounted on the fuselage. The Lyulka AL-7 engines were housed in slim, pylon mounted, pods at approximately 1/3 span. Because the wings and engine nacelles were too small to house a conventional undercarriage, the Il-54 used a bicycle undercarriage arrangement, with nose and main gear units on the centreline of the aircraft, at each end of the bomb bay. This arrangement meant a conventional rotating takeoff would be impossible.
