The Z-18F is an anti-submarine variant of the Z-18 medium-lift helicopter developed by the Changhe Aircraft Industry Group (CAIG). The helicopter, with a maximum take-off weight of 13.8t, can be deployed on smaller surface combatants of the People’s Liberation Army Navy (PLAN). It forms a part of the helicopter wing aboard the Liaoning (CV-16) aircraft carrier.
The Z-18F is equipped with an electro-optic/infrared sensor, a dipping sonar, and a chin-mounted surface search radar. It can carry up to 32 sonobuoys and four Yu-7 light-weight ASW torpedoes or YJ-9 anti-ship missiles.
Powered by three WZ-6C turboshaft engines, the Z-18F ASW helicopter attains a top speed of more than 330km/h and a maximum range of 900km.
Ka-27/Ka-28
Ka-27 or Ka-28 (export designation) can conduct missions from a variety of naval vessels to counter modern subsurface and surface threats.
The Ka-27 helicopter made its first flight in December 1973 and is used by the naval forces of Russia, Ukraine, Vietnam, China, and India. The helicopters are equipped with VGS-3 dipping sonar and sonobuoys to track and detect submarines.
The helicopter is capable of firing torpedoes and anti-submarine missiles and can also be armed with PLAB-250-120 anti-submarine bombs and OMAB bombs. The Ka-27 has a flight range of 900km.
AW159 Lynx Wildcat
The AW159 Lynx Wildcat is an advanced multi-role, maritime and utility aircraft produced by AgustaWestland for the UK Ministry of Defence (MoD). Based on the Lynx family of helicopters, the AW159 Wildcat will replace the Lynx fleet in the British Army and Royal Navy.
The airframe design of the Lynx Wildcat is built to operate off the smallest frigates and offshore patrol vessels and corvettes. The helicopter integrates AESA radar, active dipping sonar, electro-optical device, ESM and defence aids suite, making it one of the best ASW helicopter in the world.
Onboard sensors and mission systems enable the Lynx Wildcat to autonomously find and track surface and sub-surface targets while its air-to-surface missiles, torpedoes, depth charges, rockets and guns ensure the engagement of such targets. The AW159 Lynx Wildcat has a maximum endurance of two hours and 42 minutes.
Super Lynx 300
The Super Lynx 300 ASW/ASuW helicopter is a multi-role naval helicopter produced by AgustaWestland. It is a successor to the combat-proven Lynx helicopter already deployed by 15 nations worldwide.
The Super Lynx 300 is designed to operate day or night from small-sized warships in all weather conditions. The onboard mission equipment such as a 360° multi-mode surveillance radar, electro-optical surveillance system and active dipping sonar ensure the autonomous detection and pursuit of surface and submerged targets.
The Super Lynx 300 is armed with torpedoes and depth charges to attack submarines while pintle-mounted 12.7/7.62mm machine guns, anti-ship missiles and rockets ensure the engagement of potential surface threats. The helicopter has a maximum range of 564km and a maximum endurance of three hours.
S-70B SEAHAWK ASW / ASuW Helicopter
