The Kaman HH-43 Huskie was a helicopter used by the United States Air Force, the United States Navy and the United States Marine Corps from the 1950s until the 1970s. It was primarily used for aircraft firefighting and rescue in the close vicinity of air bases, but was later utilized as a short range overland search and rescue aircraft during the Vietnam War. Under the U.S. Navy's pre-1962 aircraft designation system, U.S. Navy and U.S. Marine Corps versions were originally designated as the HTK, HOK or HUK, contingent upon their use as training, observation or utility aircraft.

Design and development

The Huskie had an unusual inter-meshing contra-rotating twin-rotor arrangement with control effected by servo-flaps. The first prototype flew in 1947 and was adopted by the U.S. Navy with a piston-engine. It was later adopted by the Air Force in turboshaft HH-43B and F versions.

Operational history

This aircraft saw use in the Vietnam War with several detachments of the Pacific Air Rescue Center, the 33d, 36th, 37th, and 38th Air Rescue Squadrons, and the 40th Aerospace Rescue and Recovery Squadron, where the aircraft was known by its call sign moniker "Pedro". The HH-43 was eventually replaced by newer aircraft in the early 1970s.
