The Mil Mi-14 ( Russian Миль Ми-14 , NATO code name : Haze ) is an amphibious-compatible helicopter for anti-submarine and mine defense developed and manufactured by Mil in the USSR . The Mi-14 was based on the Mil Mi-8 and therefore has the same external dimensions. The two Isotow TW3-117MT shaft turbines with 1435 kW each (= 1950 WPS) enable a top speed of 230 km / h and a cruising speed of 215 km / h. Torpedoes and depth charges can be carried in an internal weapon bay.

The first flight of the W-14 prototype took place in September 1968. It was not put into service until 1977 as a replacement for the older Mil Mi-4 , which was equipped with a piston engine . The Mi-14 was manufactured in a plant in Kazan . 230 units had been built by 1991.

Versions

  • W-14: Prototype of the Mi-14
  • Mi-14PL ( NATO code name : "Haze-A"): Submarine hunting (ASW) version. Equipped with a towed magnetic locator APM-60 MAD (magnetic anomaly detector), up to 36 sonar buoys of the type RGB-MN1 and a retractable sonar system of the type OKA2, furthermore an I2-MA search radar. The armament consists of a single AT-1 or APR-2 torpedo, a “Skat” nuclear depth charge or up to twelve conventional depth charges (12 × caliber 50 kg, the type “PLAB 50/65” or 8 were used × with a caliber of 250 kg, type "PLAB 250/120"), there were also two optional dropping containers in the stern, each for two naval marker bombs. Optional naval marker bombs "Day" of the type "OMAB 25-12D" or naval marker bombs "Night" of the type "OMAB 25-8N", which could also be installed mixed.
Furthermore, these containers could be exchanged, also individually, for up to two heated drop containers for sea marker buoys of the type "Poplawok B". These radio buoys worked on the frequency of the search radar and, if they were detected by the radar beam, sent a signal to the radar and appeared as a radio measuring contact point on the radar screen.

The total of nine machines that were used in the People's Navy of the GDR had the equipment and technology for the use of torpedoes as well as the "Skat", which could also be used as a nuclear weapon, in addition to the equipment for the use of depth charges. The technical equipment for this was stored at Parow airfield, the electrical technology was built in. The torpedoes as well as the “Skat” were not kept in stock in the People's Navy, the helicopter crews were not trained for their use. The use of the two types of torpedoes was not possible in the western Baltic Sea due to the lack of water depth for the minimum immersion depth of the torpedoes. The target acquisition and tracking technology as well as the computational equipment of the Mi-14PL were convertible with those of some Soviet coastal missile systems and those of some systems of Soviet high-speed rocket boats, such as those of the high-speed rocket boats used by the People's Navy and those of the People's Navy mobile coastal missile positions. As a result, the complexes were able to act together, such as target acquisition by a Mi-14PL as well as data transmission to the missile speedboat or the mobile coastal missile position. As a result, the launch bases remained passive in terms of radio measurements and could therefore not be located before a rocket was launched. Another advantage was that the Mi-14PL's radar, due to its greater operating altitude as a “flying radio measuring station”, had a much larger detection radius than, for example, a relatively low-lying radar of a rocket speedboat.

The interaction of Mi-14PL and rocket speedboats was common practice in the Volksmarine and was practiced regularly. Only the technical possibility is known about the interaction with coastal missile positions.

further versions:

  • Mi-14PL: Version with the possibility of using the Ch-23 guided missile.
  • Mi-14PLM: upgraded ASW version
  • Mi-14PŁ: Polish name of the Mi-14PL. Also known as the Mi-14PW.
  • Mi-14BT (NATO code name: "Haze-B"): Mine clearance version with traction means for up to 3 t heavy active or passive clearing device on the partially glazed fuselage rear
  • Mi-14PS (NATO code name: "Haze-C"): Search and rescue (SAR) version with folding searchlights, double-sized doors and swiveling rescue winch for loads of up to 300 kg based on the Mi-14BT.
  • Mi-14PX: ​​SAR training version of the Polish Navy. A Polish Mi-14PL was converted to the Mi-14PX after the submarine hunting equipment was removed.
  • Mi-14PSch Eliminator: Conversions of Mi-14BT into fire-fighting helicopters. The conversion will cost about $ 1 million.
  • Mi-14GP: civil version.
  • Mi-14P: civil transport helicopter for 24 passengers
