After the cessation of work on the plane "73" OKB AN. Tupolev end 1948 g. to start working on a modification of the bomber, but with a twin-engine VC-1. The CB VY. Klimov on the basis of the engine "Ning-I» have managed to create a more powerful engine VC-1 with traction 27 000 kgf. The EDO AN. Project Tupolev aircraft was designated "81". 23 December 1948 g. the government issued a decree on the construction of "81" aircraft with VC-1.
In August 1949 g. came another decree of the USSR government, Where, in particular, said the termination of production of IL-28 bomber and the preparation of a series of Tu-14 with engines VK-1. A. N. Tupolev still got his way. Resolution obliged to immediately begin transmission of drawings at the production plant. The first five serial Tu-14 were to pass by September 1950 g. Meanwhile, in OKB SV. Ilyushin not put up with this decision, their bomber Il-28 with the engine RD-45F has been tested and has shown good results. Then, with engines VK-1 aircraft was put into production on three plants.
To speed up the work, It intended to modify the previously designed machine "73", removing its third motor. In March 1949 g. preliminary design was ready and 4 May be given for the conclusion of the Air Force. Military projects considered and rejected due to inefficient placing defensive weapons, and increase up to five-man crew.
20 August 1949 g. published a new decree number 3568-1477 with changed requirements: the crew of three men, defensive armament 4 gun. The aircraft received the new designation Tu-14 2 VK-1. To speed up the used glider "73", increasing the diameter of the nose and the central fuselage, stern lengthened on 0,4 m. Established a model bomb armament and increased bomb bay. Once obtained from the Air Force TTT , the Design Bureau started to produce working drawings and started the construction of the aircraft. In October 1949 g. it was built. Factory tests took place from the plane 13 October 1949 g. by 21 January 1950 city, I conducted their test pilot F.F. Opadchiy. After state tests was noted, that the aircraft performance data generally satisfy military. After completions gun mount and retests plane was recommended for serial production in embodiments bomber and torpedo.
Serial production of the Tu-14T ("81T") It was launched at the Irkutsk plant. In summer 1950 g. The first two production aircraft Tu-14 were flown to Moscow in order KB, where they were converted into torpedo - Tu-14T and reconnaissance - plane "89". After the state control testing aircraft received a satisfactory evaluation and Air Force was again recommended by the Fleet Air Arm. It noted, that distance, volume equipment, armament Tu-14 meets the requirements of the military. At the same time the plane inferior to IL-28, Tu-14 to the maximum speed on 57 kmh, practical ceiling on 1300 m, as well as the rate of climb and takeoff and landing characteristics.
While it decides the fate of the Tu-14, GK NII VVS, A. N. Tupolev was able to prove the Navy Command, that the Tu-14 in the embodiment of torpedo - exactly, it is necessary to fleet. Compared to IL-28, TU-14 gruzootseke significantly more and better suited for suspension mines and torpedoes. Large range and an expanded equipment made Tu-14 more suitable for operations at sea. Alteration is mainly concerned mine-torpedo weapons. It was built in the Irkutsk factory 147 torpedo bombers Tu-14. Operation of the Tu-14 was short-lived, to 1957 g. all of them were written off. Built scout "89" made its first flight 23 Martha 1951 g. (A.D. Flight). In the series "89" is not passed, as I have already built standard IL-28R.
