systems production life.
Designation: Kamov Ka-25 (Hormone)
Classification Type: Anti-Submarine Helicopter
Contractor: Kamov - Soviet Union
Country of Origin: Soviet Union
Initial Year of Service: 1966
Number Built: 460
Operators: India, Syria, Ukraine and the Soviet Union (Russia).
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.
No fewer than 450 Ka-25's were produced and delivered to the Soviet Union
and Ukraine along with India and Syria. The type has slowly been removed
from frontline service in the Russian Navy though it may continue in some
quantity with other navies. The Ka-25BSh represents the dedicated ASW
variant and the Ka-25PS represents the dedicated SAR variant of the Hormone
brand.
