The technical revolution connected with the advent of jet engines to power aircraft in fhe post-war period has required new decisions in the bombing aviation. In addition to work on intercontinental strategic delivery systems in post-war period in KB were actively working on a series of subsonic front-line and long-distance bombers. The beginning of this area put the test and fine-tuning tupolev's first jet - aircraft «77» (TU-12) built on the basis of piston serial Tu-2, and this became an excellent school in the development of new propulsion technology. This machine was followed almost five years fine-tuning a family of medium-and front-line Tu-14 bombers covered by the draft «73», «78», «79» and «81», culminating in the creation and adoption of the Navy aircraft good for its time torpedo-bomber Tu -14T.
"73" (TU-14 2 "NIN-1" + "Dervent-5")
"73" (TU-14 2 "NIN-1" + "Dervent-5") is a mid-range bomber. Prototype was built, serial production started. First flight - 20 December 1947. The aircraft arrangement was characterized by the third engine installed in rear fuselage which was used during take-off and low-altitude penetration. It was the first aircraft of TU-14 jet bombers family.
"78" (TU-16 2 "NIN-1" + "Dervent-5")
"78" (TU-16 2 "NIN-1" + "Dervent-5") is a photo-reconnaissance aircraft. Prototype. Represents a photo-reconnaissance version of "73" (TU-14). First flight - 7 May 1948.
"81", "91T" (TU-14 2VK-1, TU-14T 2VK-1)Tu-81 [Type-35] - service designation Tu-14; later the NATO Reporting Name 'Bosun' was assigned; sometimes also reported as Tu-89 "81", "91T" (TU-14 2VK-1, TU-14T 2VK-1) is a front-line bomber, torpedo- and mine-carrier. Represents a final serial version of TU-14. First flight was in October, 1949, and first seen publicly at the 1952 Soviet Aviation Day, Tushino.
One of the first jet-powered aircraft was the TU-14 medium jet-powered bomber-torpedo-carrier adopted by the Naval Air Force of the country. The Tu-14 Bosun was a twin-engine land-based torpedo-bomber operated by Soviet naval air arm. It had two 6040 lb. st. (2700kg) Klimov VK-1 turbojets under the wings. Two fixed forward-firing cannon were fitted, along with two 23mm cannon in tail turret.
For overwater flights the aircraft was equipped with an autopilot, special flight and navigation equipment and with a set of airborne equipment to monitor operation of the turbine engines. Good adaptability of the aircraft design fo manufacture made it possible fo build 42 aircrafts in the first year of its production at the Plant. The TU-14 aircraft was adopted by the Naval Air Force which essentially improved combat capabilities and radius of action of the coastal aviation. More than fifty aircrafts of this type were delivered fo China.
Although the Tu-14 was heavier IL-28, but the tupolev's machines range was 410 kilometers longer than that of Ilyushin's and bomb-load was 1.5 times higher. Therefore, Tu-14 began serial production as a torpedo bomber for many years with the Navy. Version TU-14T intended for Navy aviation was produced in series. It entered service in 1949, and in all about 150 TU-14 were producedwhich were operated by mine and torpedo aviation units up to late 1950s. Several tens of the aircraft were delivered to China. Built only in small numbers because of the success of the Il-28.
