Early designs Tupolev Tu-142
the tu-142m powered 4 11,033 kw (14,795 shp) kuznetsov nk-12mv turboprops, drive huge contra-rotating av-60n propellers.
in late 1950s navy developed ugm-27 polaris, submarine-launched ballistic missile (slbm) range of more of 1,800 kilometres (1,000 nm). navy test-fired rocket boosters perfect design, culminating in first underwater launch of ballistic missile uss george washington on 20 july 1960. polaris became operational on 15 november year, when george washington left charleston, south carolina, complement of nuclear-armed polaris missiles.
the soviet government consequently ordered tupolev , other aircraft design bureaus study possible dedicated anti-submarine warfare (asw) designs. tupolev designed tu-95plo (protivolodochnaya oborona, or asw), development of tu-95 equipped sonobuoys, anti-submarine mines , torpedoes. carry 9,000 kg (19,841 lb) payload maximum loiter time of 10.5 hours. design dropped, however, because lacked powerful radar, thermal imaging (infrared) system , magnetic anomaly detector (mad). on 28 february 1963, council of ministers (the highest executive , administrative body of soviet union) issued directive tupolev requiring bureau develop long-range asw aircraft.
the resultant design named tu-142 , had features in common tu-95rt. ventral , dorsal gun turrets removed, large dielectric radome housing uspeh radar system, replaced thermal imaging system located in smaller fairing. left tail turret twin 23-mm am-23 cannons, along electronic countermeasures, defensive armament. aircraft s search-and-targeting system featured berkut (golden eagle) 360° radar. complex navigation system integrated weapons targeting system. structural differences included airfoil change wing, expanding area 295 m (3,172 ft). area of elevators increased 14%, , improved hydraulic actuators fitted. metal fuel tanks replaced rubber bladders. allow tu-142 operate semi-prepared runways, tu-95 s four-wheel main undercarriage bogies replaced six-wheel units; main undercarriage fairings modified.
the first tu-142 (construction number 4200) built @ kuibyshev aviation plant in samara. performed first flight on 18 june 1968, test pilot i. k. vedernikov @ controls, taking off zhukovsky airfield southeast of moscow. testing indicated fuselage needed lengthened @ least 1.5 m (4.9 ft) accommodate new combat equipment. therefore, second prototype (c/n 4201) joined flight-test programme on 3 september 1.7-metre (5.6 ft) front fuselage stretch, modification found on subsequent tu-142s. third , final development tu-142 entered flight test on 31 october, complete full equipment suite. in may 1970, soviet naval aviation (av-mf) – air arm of soviet navy – began receiving production tu-142s operational trials.
