A single HH-43 was assigned to Dover from 1959 to 1962.
The “Huskie” was used primarily for crash rescue and aircraft fire-fighting. It was in use with the U.S. Navy when delivery of the H-43As to the USAF Tactical Air Command began in November 1958. Delivery of the -B series began in June 1959. In mid-1962, the USAF changed the H-43 designation to HH-43 to reflect the aircraft’s rescue role. The final USAF version was the HH-43F with engine modifications for improved performance. Some -Fs were used in Southeast Asia as “aerial fire trucks” and for rescuing downed airmen in North and South Vietnam. Huskies were also flown by other nations including Iran, Colombia and Morocco. The H-43 Huskie set an altitude record of 10.000 m and numerous rate of climb records. During the Korean and Vietnam Wars, the Huskie flew more rescue missions than all other aircraft combined – with the best safety record of any U.S. military aircraft.
Unique aspects of the HH-43 are its wood constructed rotors. By warping the blades causes the aircraft to climb or descend. Operation of large tabs on the trailing edge of each blade causes the warping.
