From aerospace manufacturer, de Havilland Canada, the DHC-4 Caribou is a twin-engine, short takeoff and landing (STOL) cargo aircraft originally developed as a military cargo and troop carrier. The Caribou was conceptually based on the STOL performance of the smaller de Havilland DHC-2 Beaver and DHC-3 Otter, but with greater cargo capacity.
The Caribou first flew on July 30, 1958, and was introduced into mainline service in 1961. De Havilland built a total of 307 Caribou planes, with the majority going into military service, and the rest serving civil missions. 32 countries’ militaries flew the Caribou, including that of the United States. Designated first as the CV-2 and then as the C-7, the United States Army and the United States Air Force operated a total of 159 of the planes. Spain, Kenya, India, and Australia also used the airframe until 2009.
