Mil Mi-14 / V-14

mi-14


The Mi-14, allocated the NATO reporting name 'Haze', is an amphibious version of the Mi-8 intended to replace the Mi-4 in the ASW and mine counter-measure roles with the Soviet navy.

The prototype SSSR-11051, initially designated V-8G, then designated V-14, was first flown in September 1969 with a redesign watertight hull and sponsons containing fuel and a retractable undercarriage and with Mi-8 power plant. The sponson carry inflatable flotation bag each side at rear and small float the under tailboom. It has marine-type rudders on either side of the aft portion, into which the rear landing gear units retract. Two forward-retracting single-wheel nose units and two rearward-retracting twin-wheel main units. A fairing for the search radar is fitted under the nose, and a dipping sonar or magnetic anomaly detector beneath the root of the tail boom.

Production aircraft feature two 1,434kW Klimov TV3-117MT turboshafts, with a special anti-corrosion finish. Radar is the I-2M or I-2ME Initziativa undernose radar. Instrumentation includes RW3 radio altimeter, ARK-9 and ARK-U2 ADFs, DISS-15 Doppler, Chrom Nikiel IFF, AP34-B autopilot/autohover system and SAU-14 autocontrol system.

Using the twin powerplants and rotor system of the Mi-17, the 'Haze' went into service in 1977 and has become the basic shore-based helicopter with the Soviet navy for use in three distinct roles. Although amphibious, the Mi-14 is only intended for occasional operations from water. Initial deployment was with shore-based antisubmarine units, although Haze was also expected to be oper-ated from the Moskva Class helicopter car-riers and the Kiev Class antisubmarine cruisers.

In the main cabin, which in transport versions can be equipped with 32 seats, a mission crew of three or four sit round a tactical display served by the radar, a towed MAD (magnetic anomaly detection) 'bird' and dipping sonar. Some ex-amples have additional radio aerials and a few have a rescue hoist above the large sliding door on the left side. Fuel is housed in large tanks along the sides under the main floor, and poss-ibly also in the rear sponsons, leaving the central compartment free for use as a weapon bay, with belly doors.

Two versions have been identified: Haze A, the ASW variant with undernose search radar, towed MAD, and an internal weapons bay; and the Haze B mine countermeasures variant.

It was estimated in mid-1983 that there were 65 for the AV-MF and 12 for Bulgaria. By 1991, about 230 had been delivered, with exports to Bulgaria, Cuba, East Germany, North Korea, Libya, Poland, Romania, Syria and Yugoslavia.
