The Mil Mi-14 'Haze' is a navalized version of the ubiquitous Mi-8, specializing in the coastal anti-submarine warfare role as opposed to the Ka-27 which is usually operated from ships. Considerable revision of the fuselage was necessary to provide this new helicopter with amphibious capabilities, thanks to this it has a pronounced boat hull bottom with a sponson on each side and a small float under the tail boom while at the same time incorporating a retractable undercarriage and an enclosed weapons bay. Avionics and weapons include a Doppler radar, a magnetic anomaly detector (MAD), and sonobuoy capabilites in addition to torpedoes and depth charges, while some variants are specialized in the search and rescue (SAR) role with rescue hoists. A small number were exported to Warsaw Pact nations and various other Soviet client states.

The Mi-14 was first flown in September 1969, entering service in only 1975 as a result of apparent development problems. The principal ASW version is known as the Mi-14PL 'Haze-A' while a mine countermeasures model with a starboard-side fuselage strake is the Mi-14BT 'Haze-B' and a dedicated SAR variant which can carry ten 20-person liferafts and a rescue hoist is the Mi-14PS 'Haze-C'.
