Kaman SH-2 Seasprite

The Kaman SH‑2 Seasprite is a compact twin‑engine anti‑submarine warfare and utility helicopter developed by Kaman Corporation in the early 1950s. First flown on 2 March 1959, the prototype originally featured a single Allison T63 turboshaft; production models adopted a more powerful T63‑A-5 engine and later a twin‑engine arrangement for improved safety over water. The Seasprite entered U.S. Navy service in 1962, initially serving aboard the s, and later operated from guided‑missile destroyers and frigates, where its small footprint allowed deck landing in rough seas. Key features include a coaxial rotor system derived from Kaman’s patented intermeshing design, a fully articulated main rotor, retractable landing gear, and a spacious cabin that can be configured for search and rescue, transport, or electronic warfare missions. Over its production run, more than 600 airframes were built, and variants such as the SH‑2F and SH‑2G Super Seasprite incorporated upgraded avionics, glass cockpit displays, and more powerful engines. The aircraft’s versatility and survivability established it as a benchmark for ship‑borne helicopters, influencing subsequent naval rotorcraft development and cementing Kaman’s reputation as an innovative aerospace manufacturer.
