Sensors: The Ka-25s of the Indian Navy featured a search radar, a dipping sonar in the cabin rear and a canister of sonobuoys fitted externally.

Comments: Seven Ka-25s (all being ex-Soviet Navy) were on order for the Indian Navy, and these formed the equipment of the new INAS 333 Squadron, commissioned in December 1980. Each operated by a two-man crew, the Ka-25s were essentially for ASW with secondary surveillance and SAR duties. Endurance was three hours, but the helicopter had a limited night and all-weather sonar-dipping capability. The Ka-25 are still in service with the Naval Air Arm, albeit in a limited role.
