The SH-2 Seasprite is an anti-submarine / surface ship helicopter developed by the US Navy in 1972. The design was based around the Kaman utility/rescue helicopter. The Seasprite Sh-2D was developed for the Light Airborne Multi-Purpose System (LAMPS) program. LAMPS extends the sensor reach of Naval vessels by linking to the radar/sonar/electronic/magnetic sensors aboard suitably-equipped helicopters. With a LAMPS helicopter, the mothership, or indeed the entire fleet, can detect threats over the horizon and deep underwater.
Seasprites carry a suite of sensors for tracking both surface and underwater contacts. The distinctive disc in the helicopter's chin houses a LN-66HP search radar. Later models (SH-2G) are fitted with a FLIR/laser designator pod. Sonobouys dropped into the water are used to hunt for submarines. On earlier models, the sonar returns would be processed by the Seasprite's mothership whilst the SH-2G is fitted with its own onboard processor. The SH-2 can also deploy a Magnetic Anomaly Detector probe to pinpoint a sub's location. In the minesweeping role, the Seasprite employs a Kaman Magic Lantern airborne laser mine detection system to scan below the waves for submerged mines.
The SH-2 Seasprite can be armed with various air-to-surface weapons including Mark 46 or Mark 50 torpedoes, AGM-65 Maverick infra-red guided missiles, AGM-119 Penguin infra-red guided missiles and AGM-114 Hellfire laser-guided missiles. Door guns can be pintle-mounted to the cabin but this is rarely seen.
Within the US Navy, the Seasprite's role has been taken over by the SH-60 Sea Hawk. Many variants of Seasprites still fly in the Navies of other countries including Egypt, Australia, New Zealand and Poland.
