1952 with Naval Aviation. About 150 were produced and served with the mine-torpedo regiments of Naval Aviation until 1959. It was given the NATO reporting name Bosun. After it was withdrawn from service, several were used for various test programs, including one evaluating ramjet engines. Up to 50 used Tu-14Ts were delivered to the Chinese People's Liberation Army Air Force although quantities and dates cannot be confirmed. The second preproduction Tu-14 was converted into a day or night photographic reconnaissance aircraft with the OKB designation of "89". The conversion was fairly minor and involved an unpressurized central cabin that housed two automatic pivoting cameras, two fuel tanks and another camera fitted in the bomb bay and another camera for oblique photography was mounted in the aircraft's tail for the daylight photography role. All cameras and their viewports were electrically heated to prevent misting and icing at altitude. For night photography, the fuel tanks and camera in the bomb bay were removed and a variety of flare bombs were carried to illuminate the targets. In addition, the screen of the PSBN-M navigation radar could be photographed by a special camera and both the pilot and navigator could record their own observations using a voice recorder. However, the VVS had already decided to use the Il-28R reconnaissance version of the standard Il-28 by the time that the "89" first flew on 23 March 1951 and Tupolev decided not to submit it for State acceptance trials.
