Komisia de Havilland Kanada DHC-4 Caribou (označený armádou Spojených štátov amerických ako CV-2 a neskôr C-7 Caribou) je kanadské špecializované nákladné lietadlo so schopnosťou krátkeho vzletu a pristátia (STOL). Caribou prvýkrát vzlietol v roku 1958 a hoci bol väčšinou vyradený z vojenských operácií, stále sa používa v malom počte ako robustné lietadlo "bush".

The Master of the Short Field

Komisia de Havilland Kanada 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.
