DHC-5 Buffalo
Manufactured 1965–1972, 1974–1986
The de Havilland Canada DHC-5 Buffalo is a short takeoff and landing (STOL) utility transport turboprop aircraft developed from the earlier piston-powered DHC-4 Caribou. The aircraft has extraordinary STOL performance and is able to take off in distances much shorter than even most light aircraft can manage.
Development
The Buffalo arose from a 1962 United States Army requirement for a STOL transport capable of carrying the same payload as the CH-47A Chinook helicopter. De Havilland Canada based its design to meet the requirement on an enlarged version of its DHC-4 Caribou, already in large-scale service with the United States Army, to be powered by General Electric T64 turboprops rather than the Pratt & Whitney R-2000 piston engines of the Caribou. (It had already flown a T64-powered Caribou on 22 September 1961)
Design
Operational history
In late 1965, one of the prototype DHC-5s operated by the U.S. Army was deployed to Bien Hoa Air Base in South Vietnam for a three-month evaluation period, assigned to the 2nd Flight Platoon of the 92nd Aviation Company.
The Royal Canadian Air Force first acquired 15 DHC-5A designated as CC-115 for tactical transports. These were initially operated at CFB St Hubert, QC by No. 429 Squadron in a tactical aviation role as part of Mobile Command. In 1970, the Buffalo aircraft were transferred to a transport and rescue role with No. 442 Squadron, No. 413 Squadron and No. 424 Squadron as part of Transport Command. No. 426 Squadron also flew the aircraft for training. Some were leased back or loaned back to the factory for trials and eventually returned to military service.
