construction

The aircraft was designed as a shoulder - wing aircraft with a positive V-position of the wings. The engines used were two Pratt & Whitney R-2000 -7M2 with 1081 kW (1450 hp) each.

The DHC-4 Caribou could carry 32 soldiers or two jeeps or a load of 3048 kg. The loading ramp could also be used by parachutists .
