The Russian Naval combat-transport helicopter Ka-29 (NATO Designation: 'Helix-B') is derived from the Kamov Ka-27.  Production began in 1974 and entered the Russian Navy service in 1987.

 The helicopter is equipped with: a 7.62 mm flexibly mounted machine gun; quadricycle landing gear for landing on ship decks; ballonnets for water landings.  The cabin can carry 16 armed troops, or 4 stretchers with 8 passengers.  Combat, internal and slung payloads are 1800 kg, 4000 and 4000 kg, respectively.  Turbine engines that may be used are either the TV3-117V or TV3-117VMA (both 2200 shp).
