Description: The Kamov Ka-27 was developed to replace the Ka-25 shipborne helicopter in the Soviet Navy performing Anti-Submarine Warfare (ASW) and Search and Rescue (SAR) missions. In addition, the Ka-27 was designed to operate at night and all-weather conditions which were the main shortfalls of Ka-25 aircraft. The NATO nicknamed this aircraft as Helix. The Ka-28 is the designation assigned to export models and Ka-32 designation refers to variants intended for the civil/commercial market. The Soviet Union's Navy also developed the Ka-29 shipborne assault helicopter and the Ka-31 airborne radar helicopter based on the Ka-27 platform. The aircraft uses Kamov's characteristic twin three-blade coaxial contra-rotating rotors design making the tail rotor irrelevant and unnecessary. It is powered by two TV3-117V/VMA turboshaft engines each rated at 2,200-hp. The Ka-27 prototype first flew in 1973 and entered service in 1981.

The Ka-27PL is an ASW helicopter intended to hunt down and destroy submerged submarines and the Ka-27PS is optimized for search and rescue missions with room for up to 16 passengers. Besides, these aircraft can also engage surface ships using anti-ship missiles. The Ka-27 helicopter is the standard shipborne helicopter in the Russian Navy operating from frigates, destroyers, cruisers and aircraft carriers. It can be equipped with Magnetic Anomaly Detector (MAD), sonobuoys, and Osminog surface search radar as well as additional sensors. The armament options torpedoes (AT-1M, VTT-1, UMGT-1, ME Orlan, APR-2 Yastreb-M, ATM-1, APR-3E), bombs (PLAB-250-120, P-50T, UPLAB-50, S-3B, OMAB1-25-12D, 25-3N), rockets and anti-ship missiles such as the Kh-35UE. The Ka-27 entered service with the Soviet Navy in 1981. The aircraft is almost obsolete and may be replaced by the Ka-27M or a new platform by 2020.
