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.
