The Mil Mi-14 (Russian: Миль Ми-14, NATO reporting name: Haze) is a Soviet shore-based nuclear-capable amphibious anti-submarine helicopter derived from the earlier Mi-8.

Design and development

[edit]

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 hours on station at a radius of 222 kilometres (120 nmi; 138 mi) from base.[2]

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,[N 1] with the mainwheels retracting into large sponsons on the rear of the fuselage. The helicopter was to be powered by two Klimov TV3-117MT turboshaft engines.[3] 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.[3][4]

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.[1]

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.[3] 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.[3]

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.[5]

Variants

[edit]
Georgian Mi-14
V-14
Prototype of the Mi-14 helicopter.[4]
Mi-14PL (NATO Haze-A)
Anti-submarine warfare helicopter, equipped with towed APM-60 MAD, OKA-2 sonobuoys and a retractable Type 12-M search radar, armed with either a single AT-1 or APR-2 torpedo, one Skat nuclear depth bomb or eight depth charges.[4][6] A single Mi-14PL was used to carry out trials with the Kh-23 (NATO designation AS-7 Kerry) air-to-surface missile but this modification does not seem to have entered service.[7]
Mi-14PLM
Improved anti-submarine warfare version with Os'minog ASW suite, with new search radar, dipping sonar and digital computer. Limited use.[8]
Mi-14PŁ/R
Polish conversion of two Mi-14PŁ (Polish designation for Mi-14PL) to search and rescue version, with ASW equipment removed, developed in 2010.[9]
Mi-14BT (NATO Haze-B)
Mine sweeping helicopter with ASW systems removed and equipped for towing Mine Countermeasures sleds. 25–30 built, with six exported to East Germany and two to Bulgaria.[8]
Mi-14PS (NATO Haze-C)
Search and rescue version with search lights and sliding doors with hoist.[10]
Mi-14PX
Search and rescue training helicopter for the Polish Navy (unofficial designation). One Polish Mi-14PŁ helicopter was temporarily converted into the Mi-14PX, then converted back in 1996.[9]
Mi-14PZh
Polish Navy's Mi-14PŁ on display at Radom Air Show 2005
Amphibious firebuster version of Mi-14BT.[11] Conversion price about USD1M.
Mi-14GP
Conversion of Mi-14PL to 24–26 seat civil passenger transport.[11]

Operational history

[edit]

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.[12] On 22 March 2015, one crashed with its pilot killed on the spot after capture and the rest of the crew captured.[13][14]

On 7 May 2022, Ukraine confirmed that Colonel Ihor Bedzay, the deputy head of the Ukrainian Navy, was killed when his Mi-14PS was shot down by a Russian Su-35.[15][16] A video emerged, claimed shot on 7 May 2022, showing a Su-27 family fighter engaging a Mi-14 with its 30 mm gun.[17]

Operators

[edit]

By 1991, about 230 had been delivered, with exports to many Soviet allies including Bulgaria, Cuba, East Germany, Libya, Poland, and Syria.
