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

==Design and development==
Formal development of an [[anti-submarine warfare]] (ASW) version of the [[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 [[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 [[SH-3 Sea King|Sea King]], allowing it to [[Amphibious helicopter|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 TV3-117|Klimov TV3-117MT]] [[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 Mi-14 has a crew of four: a pilot, a copilot, an onboard technician, and a weapon system operator. The Mi-14PL anti-submarine version is equipped with a radar, a [[dipping sonar]] and a [[magnetic anomaly detector]].<ref name="mil mi-14 red samovar"/>

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 Helicopters|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>

==Operational history==
As part of the [[Syrian civil war]], starting from 2013, Syrian Navy Mi-14 helicopters were used as improvised bombers to drop naval mines and barrel bombs on large area targets from high altitude, mostly cities held by opposing forces.<ref>{{cite web | url=https://www.bellingcat.com/news/mena/2015/01/16/the-syrian-arab-air-force-beware-of-its-wings/ | title=The Syrian Arab Air Force, Beware of its Wings | date=16 January 2015 }}</ref> On 22 March 2015, one crashed with its pilot killed on the spot after capture and the rest of the crew captured.<ref>{{cite web | url=https://theaviationist.com/2015/03/22/syrian-navy-mi-14-crash-landing/ | title=Video shows Syrian Navy Mi-14 anti-submarine helicopter (About to) crash land near Idlib | date=22 March 2015 }}</ref><ref>{{cite web | url=https://theaviationist.com/2015/04/02/inside-mi-14-hip-crash-landed/ | title=Video filmed inside Syrian Navy anti-submarine warfare helicopter before it crashed leaked on Youtube | date=2 April 2015 }}</ref>
