SH-3H Sea King
The SH-3 Sea King has been in service for over 40 years, flying as a transport, sea rescue and anti-submarine warfare (ASW) helicopter. Replaced within the US Navy in 1995 by the SH-60 Sea Hawk, the venerable SH-3 is still going strong in many navies around the world.
Submarines are a major threat to any surface fleet. Whilst sub-hunting ships exist, helicopters, with their ability to operate far out from carriers, are preferred since they can intercept underwater threats before they get in range of friendly vessels.
The SH-3H Sea King carries a suite of advanced sensors operated by 2 systems operators seated in the cabin behind the pilot and co-pilot. A Marconi surveillance radar sweeps the surface for contacts. In addition, the SH-3H can deploy 2 forms of sensors buoys for searching beneath the waves. The AN/AQS-13 or AN/AQS-18 dipping sonar is a buoy that is lowered down into the water. The active sonar sweeps in a 180 degree arc for underwater contacts. The SH-3H can also trail out a ASQ-81 Magnetic Anomaly Detector (MAD) behind it. The MAD watches for slight fluctuations in the earth's magnetic field - a tell-tale signature of a submerged submarine.
If it finds a sub, the SH-3H can drop up to 2 MK46 sonar-homing torpedoes or a variety of depth-charges (including variants with nuclear warheads).
