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.^[1]

Air Mobility Command Museum at Dover Air Force Base, Delaware has HH-43, AF Serial Number 62-4532, on display.
The Helicopter Museum Bueckeburg in Germany has an HH-43 on display.
The Pakistan Air Force museum in Karachi has an HH-43 Huskie on static display in the open.

The New England Air Museum has an HH-43A (AF Ser. No. 58-1837) airframe stored.

HH-43B

Hill Aerospace Museum at Hill Air Force Base, Utah has an HH-43B on display.^[2]
The Midland Air Museum in Coventry, England is carrying out a restoration on HH-43B, AF Ser. No. 62-4535. The aircraft is usually viewable on display; 24535 is one of only two examples on display in the UK.
The National Museum of the United States Air Force at Wright-Patterson AFB, Ohio has HH-43B, AF Serial Number 60-0263, on display. It was assigned to rescue duty with Detachment 3, 42nd Aerospace Rescue and Recovery Squadron, Kirtland AFB, New Mexico prior to its retirement and flight to the museum in April 1973.^[3]
The Olympic Flight Museum in Olympia, Washington has an airworthy HH-43B Huskie on display.^[4]
The Military Firefighter Heritage Display on Goodfellow Air Force Base in San Angelo, Texas has a restored HH-43B on display. The tail number displayed after restoration is 58-1481, but should probably be 58-1841 (its number before restoration, and a number corresponding to an HH-43B). This Huskie was a ground trainer (1959–1976) at Sheppard AFB, Texas, so it retained the square-tail empennage that was removed from almost all other Huskies after repeated rotor strikes in heavy winds.
The Royal Thai Air Force Museum, Bangkok, Thailand has an HH-43B on display in the open.^[5]
