The de Havilland Canada DHC-4 Caribou (designated by the United States military as the CV-2 and later C-7 Caribou) is a Canadian-designed and produced specialized cargo aircraft with short takeoff and landing (STOL) capability. The Caribou was first flown in 1958 and although mainly retired from military operations, is still in use in small numbers as a rugged “bush” aircraft.

The Master of the Short Field

The de Havilland Canada DHC-4 Caribou (designated CV-2 and later C-7 in U.S. service) was designed to do the impossible: carry the payload of a medium transport while operating from the tiny, rugged airstrips normally reserved for light bush planes. Known for its incredible Short Take-Off and Landing (STOL) capabilities, the Caribou became an indispensable asset during the Vietnam War, delivering supplies directly to remote Forward Operating Bases that no other fixed-wing aircraft could reach.

Engineering for the Jungle Strip

  • Double-Slotted Flaps: The Caribou used a sophisticated full-span double-slotted flap system. This allowed the wing to generate massive lift at very low speeds, enabling the aircraft to “climb like a homesick angel” immediately after a short takeoff roll.
  • Upswept Tail and Rear Ramp: To facilitate rapid loading of vehicles and palletized cargo, the rear fuselage was sharply upswept. This provided a high-clearance rear loading ramp that could be opened in flight for paradrops or used on the ground for drive-on access.
  • Reversible Pitch Propellers: To achieve its legendary landing distances, the Caribou utilized reversible pitch propellers. Upon touchdown, the pilot could “reverse” the thrust, allowing the aircraft to stop in a distance shorter than its own wingspan.
  • Long-Stroke Landing Gear: The “bird-like” landing gear was designed with massive shock-absorption capabilities to handle the high sink rates and “controlled crashes” associated with landing on uneven, unpaved terrain.

Operational Legacy: The “Gravel Truck” of Vietnam

  • Inter-Service Rivalry: The Caribou was so successful at tactical airlift that it sparked a famous dispute between the U.S. Army and Air Force over who should operate fixed-wing transports. Eventually, the Army’s CV-2s were transferred to the USAF as C-7s.
  • Low-Altitude Extraction (LAPES): The Caribou was a pioneer in the Low Altitude Parachute Extraction System, where cargo was pulled out the rear ramp via parachute while the aircraft flew just feet above the runway.
  • Durability: The aircraft was built to be simple and maintainable in the field. Its radial engines were reliable and could be serviced with minimal tools in harsh environments.
  • Global Service: Beyond the US and Canada, the Caribou served with distinction in Australia, India, and Spain. Many are still used today by private contractors for specialized heavy-lift bush operations.
