The '''Mil Mi-14''' ({{lang-ru|Миль Ми-14}}, NATO reporting name: '''Haze''') is a [[Place:Soviet Union|Soviet]] shore-based nuclear-capable amphibious anti-submarine [[Engineering:Helicopter|helicopter]] derived from the earlier [[Engineering:Mil Mi-8|Mi-8]].

==Design and development==
Formal development of an anti-submarine warfare (ASW) version of the [[Engineering:Mil Mi-8|Mil Mi-8]] transport helicopter was authorised by the Soviet Communist Party Central Committee and Council of Ministers in April 1965, with the objective of replacing the [[Engineering:Mil Mi-4|Mil Mi-4]] in the short-range, shore based anti-submarine role. The new helicopter was required to have an endurance of 2&nbsp;hours on station at a radius of {{convert|222|km|nmi mi}} from base.<ref name="Mlad1 p184-6">Mladenov ''Air International'' March 2001, pp. 184–186.</ref>

The new design (with the internal designation V-14) differed from the Mi-8 in having a boat-like hull similar to the Sea King, allowing it to operate off the water, and a retractable four-point undercarriage,{{#tag:ref|The first retractable undercarriage to be used in a Soviet helicopter.<ref name="Mlad1 p186">Mladenov ''Air International'' March 2001, p. 186.</ref>|group=N}} with the mainwheels retracting into large sponsons on the rear of the fuselage. The helicopter was to be powered by two Klimov TV3-117MT [[Engineering:Turboshaft|turboshaft]] engines.<ref name="Mlad1 p186"/> A watertight weapons bay is fitted to the centreline of the fuselage allowing internal carriage of a single torpedo or eight depth charges, while a radome housing a search radar is fitted beneath the nose.<ref name="Mlad1 p186"/><ref name="Gunst Rus p238">Gunston 1995, p. 238.</ref>

The first prototype V-14, converted from a Mi-8 and powered by the older and less powerful Klimov TV2-117 engines, flew on 1 August 1967.<ref name="Mlad1 p186"/> Development was slowed by problems with the helicopter's avionics and due to reliability problems with the TV3-117 engines, with production at Kazan not starting until 1973, and the helicopter (now designated Mi-14) entering service on 11 May 1976.<ref name="Mlad1 p186"/>

In January 2016, Russian Helicopters confirmed to Russian News Agency TASS that no final decision to revive production had been taken, but market demand, feasibility studies – including with Moscow's defence ministry – and funding sources were under review. The programme remains a “priority” for Russian Helicopters. The company suggested the Mi-14 would appeal to civil operators in Russia's far north and those supplying the oil and gas industry, alongside the nation's armed forces. Out of the almost 300 Mi-14s produced at Kazan Helicopters between 1973 and 1986, it is estimated that just 44 examples remain in active service.<ref>{{Cite web |url=https://www.flightglobal.com/news/articles/russian-helicopters-still-analysing-revival-of-mi-14-420733/ |title=Russian Helicopters still analysing revival of Mi-14 amphibian |date=12 January 2016 |publisher=FlightGlobal}}</ref>
