Kaman HH-43F Huskie

Kaman began development of the Huskie in 1950 for the Navy and Marine Corps. The prototype first flew in 1953. The helicopter’s twin intermeshed rotor configuration eliminates the need for a tail rotor, but the angle at which the must be mounted forces the rotor blades to approach very near the ground when the aircraft is landed making it very difficult to get close to the aircraft while the rotors are turning. In 1958, the Air Force adopted the Huskie for aircraft rescue and firefighting. The strong downwash from the rotor blades could actually push a fire away from a trapped crewman and the rescue teams. A civil version of the HH-43 called the K-Max was developed during the 1990s.

Kaman SH-2F Seasprite

The Seasprite is a light anti-submarine helicopter designed to be operated from smaller warships such as destroyers and frigates. The original design of the SH-2 dates to 1957 and a navy requirement for a light utility helicopter. Kaman won the contract and began producing HU2K in 1962. In the late 1960s the Navy began to look for an anti-submarine helicopter that would be small enough to operate from destroyers and frigates. The Seasprite proved to be perfect for the job and the SH-2D version was introduced. The most significant upgrades to the design were the addition of a second engine and external weapon mounting points. The SH-2D entered service in 1971. By the mid-1980s virtually all the Seasprites built had been upgraded to SH-2F status with further electronic improvements. Seasprites remain in limited Navy service and in the service of several other nations including; New Zealand, Australia, Egypt, and Poland.

Kaman OH-43D Huskie

Kaman began development of the Huskie in 1950 for the Navy and Marine Corps. The prototype first flew in 1953. The helicopter’s twin intermeshed rotor configuration eliminates the need for a tail rotor, but the angle at which the must be mounted forces the rotor blades to approach very near the ground when the aircraft is landed making it very difficult to get close to the aircraft while the rotors are turning. The early Huskies used by the Navy and Marine Corps used a radial aircraft engine, while the later Air Force version used a turbine engine.
