Sikorsky SH-60 Seahawk Ship-borne Multi-Purpose Helicopter |
DESCRIPTION:
When the US Navy issued a requirement for an updated LAMPS III (light airborne multi-purpose system) helicopter to operate from smaller naval escorts, Boeing and Sikorsky each submitted proposals. Following a 1977 fly-off, the Sikorsky S-70L, itself a growth of the Army UH-60A, was named the winner. While the Seahawk uses the same basic airframe of the UH-60A, the SH-60B is far more expensive and complex due to the addition of extensive avionics and weapons systems. The aircraft is equipped primarily for anti-submarine warfare (ASW) and anti-ship surveillance and targeting (ASST) duties. Other capabilities include search and rescue, replenishment, and medical evacuation missions. Due to the success of the original SH-60B variant, the Navy has also developed the HH-60H special operations model and SH-60F carrier-borne ASW model. All US Navy models will be replaced by the MH-60R and MH-60S. The US Coast Guard also uses the HH-60J search and rescue version. The SH-60 has attracted customers among several US allies.
