The Kamov Ka-25 (NATO codename of "Hormone") was developed from the Ka-20, which itself was a response to a Soviet Navy requirement for a ship-borne helicopter to replace the aging Mil Mi-4 platforms. The Ka-25 became a mainstay on Soviet surface warships throughout the Cold War and played a major role in anti-submarine warfare for decades. The aircraft has since been replaced in service by the more capable Ka-32 series - another Kamov design.
The Kamov Ka-25 is a highly-recognizable helicopter for many reasons. Most notably are the twin main rotors, coaxially mounted and negating the need for a tail rotor. The elimination of the tail rotor, commonly found on traditional helicopters, means that the Ka-25 can be built to a shorter-in-length specification - a priceless attribute when considering onboard storage for a navy warship. Additionally, the stout fuselage design and tri-fin tail section are clear indicators of a Kamov design. This basic appearance is carried on in the Ka-27, Ka-28, Ka-29, Ka-31 and the Ka-32.
Crew accommodations amount to a pilot and copilot seated at front, side-by-side. if properly equipped, the cabin can provide seating for up to 12 passengers. Traditionally, the system is designed for naval operations in the way of anti-submarine warfare (ASW) and search and rescue (SAR) operations, meaning cabin space is utilized for specialized equipment. Armament can vary depending on the mission but traditionally, the Ka-25 is set up to take on two air-to-surface torpedoes and/or conventional and nuclear depth charges.
