Kaman SH-2F Seasprite

The Kaman SH-2 Seasprite is a ship-based helicopter originally developed and produced by American manufacturer Kaman Aircraft Corporation. It has been typically used as a compact and fast-moving rotorcraft for utility and anti-submarine warfare missions.

Development of the Seasprite had been initiated during the late 1950s in response to a request from the United States Navy, calling for a suitably fast and compact naval helicopter for utility missions. Kaman’s submission, internally designated as the K-20, was favourably evaluated

Operational History

n 1962, the initial UH-2 model commenced its operational service with the U.S. Navy.[3] The U.S. Navy quickly determined that the helicopter’s capabilities were greatly restricted by its single engine; thus, the service ordered Kaman to retrofit all of its Seasprites into a more capable twin-engine arrangement instead; when furnished with a pair of engines, the Seasprite was capable of attaining an airspeed of 130 knots and operating at a range of up to 411 nautical miles. The U.S. Navy would operate a total fleet of nearly 200 Seasprites to perform a variety of missions, ranging from anti-submarine warfare (ASW) operations, search and rescue (SAR) and utility transport.[
