Very little is known as yet of the Mil Mi-14, a derivative of the Mi-8, which is now in service with the shore-based units of the Soviet Naval Air Force and in Libya. It appears to have been tested in the Soviet Union at the beginning of 1974, entering service in 1975, and is now in full-scale production. It differs from the Mi-8 in that it has a watertight hull with sponsons and marine-type rudders on either side of the aft portion, into which the rear landing gear units retract. A fairing for the search radar is fitted underthe nose, and a dipping sonar or magnetic anomaly detector beneath the root of the tail boom. In all probability, the Mi-14 can be used for over-the-horizon target designation, guidance of surface-to-surface missiles and for search and rescue. It probably has a bomb bay for antisubmarine torpedoes, depth charges and other weapons.
