The decision to build the de Havilland Canada DHC-4 Caribou was taken in 1956, the object being to develop an aircraft combining the load-carrying capability of the Douglas DC-3 with the STOL performance of the Beaver and Otter. The Canadian army placed an order for two and the US Army followed with five, the US Secretary of Defense waiving a restriction which limited the US Army to fixed-wing aircraft with an empty weight less than 2268kg.
The prototype flew in July 1958, its high wing having a characteristic centre-section with marked anhedral. The rear door was designed as a ramp for items weighing up to 3048kg. In the trooping role up to 32 soldiers could be carried. The Caribou served with the RCAF as the CC-108 and with the US Army as the AC-1 (1962 designation CV-2A). As a result of its evaluation of the first five aircraft the US Army adopted the Caribou as standard equipment and placed orders for 159.
The second batch of aircraft was designated CV-2B. Following tension on the border between China and India, the US Army handed over two Caribous to the Indian Air Force in early 1963. In January 1967 the 134 Caribous still in service with the US Army were transferred to US Air Force charge as C-7A and C-7B transports. The aircraft was a general sales success and examples flew not only with air forces throughout the world, but also with civil operators. In Canadian service the Caribou was replaced by the DHC-5 Buffalo and surplus examples were sold to a number of nations including Colombia, Oman and Tanzania. Many of the Canadian aircraft had been loaned to the United Nations, seeing extensive international service. Production ended in 1973. The DHC-4A model supplanted the DHC-4 on the production line from aircraft no. 24: the two models are very similar apart from the later model's increase in weight, maximum take-off weight of the DHC-4 being 11793kg. Total production was 307.

Thanks De Haviland. | | henry pribadi, henry.pribadi08=gmail.com, 29.04.2012 Dear sirs,
I need help and information. I want to buy DHC 4 Caribou with turbo engine for cargo for operating at south asia. Could anyone help me to find the seller of DHC 4 Caribou.
Thank and regards Henry Pribadi | | A.Razak Hassan, hassan45=web.de, 17.04.2012 Hallo!I was very suprised to discover the Royal Malaysian Air Force Caribou shown with the serial nr. FM 1101 because I was flying with this Aircraft as a Crew Chief in the 60ties in Borneo, Malaysia. This Aircraft was one of four FM1100 to FM 1103 given as a gift from the Canadian Goverment to Malaysia in 1962.Unfortunately this particular Aircraft crashed into the jungle of Sarawak,Borneo after experiencing an engine failure and was written off. The Co-pilot was killed in this crash and the Captain as well as myself were injured. This crash happened in 1964.Before that, I was trained in Australia with No.38 Caribou Sqn in RAAF Richmond.The last RMAF Caribou was retired about 10 years ago and about eight or ten Aircrafts are still stored in RMAF Base Kuching,Borneo.I send my best regards to all ex-Caribou crew members. | | Bob Neal, rneal27=bellsouth.net, 12.03.2012 Flew the Caribou out of Vung Tau and Cam Rahn Bay 70-71. Had never landed on a runway less than 8000' until then. In training looking down at a 1500' runway looked impossibily short. In country there were 5 or 6 that were less than 1000'. In a strong headwind and with full flaps you could almost hover. | | W CALAME, roundbill=msn.com, 24.02.2012 Have a question, but first Thank You all for your service. I was a crewchief on a Caribo up at Fort Richardson Alaska in 1966, 12th Aviation, They were a great ship.My question is when they were transfered to the Air force how were they transported to v Vietnam and the route and fuel stops to get their. Thank You | | Charlie Dexter, cdexter1=cfl.rr.com, 10.01.2012 Sorry my earlier comment has a typo. The 1st Avn Co(FWLT)flew 18 Caribou to SE Asia, not 16. We flew in three flights of 6 each. Big Moose One, Two and Three. | | Charlie Dexter, cdexter1=cfl.rr.com, 10.01.2012 I was assigned to the 1st Avn Co (FWLT)in 1962/63 that flew 16 Caribou from Ft. Benning, GA over the ice cap, through Europe, and the middle east when we deployed to South East Asia in suport of the Vietnam War. As a 1/LT and new aviator this was a great experience flying this super aircraft half way arond the world and then throughout Thailand and Vietnam. I also was assigend to the 224th Avn Bn later on my second Vietnam tour and became the comand pilot of "Pathfinder" (62-4147)an electronic intelligence gathering modified RCV-2B shortly after she was repaired following being shot down up along the DMZ. I then became the last Army Aviator to fly the Caribou in Vietnam as 62-4147 was turned over to the USAF in Apr 1967. | | John, johm55=gmx.com, 29.10.2011 Using Caribou in Flightgear but sounds horrible. Any one got a recording of a real one I could substitute? | | Frank Huber, f.k.huber=hotmail.com, 11.10.2011 I need to get some specifics on the fuel tanks on the C-7. I have project that wants to armor the tanks for small arms fire and I have no details on the aircraft. I was a crew chief on T-29D's and they had wet wings. does the C-7 also have wet wings? how are out are they? thanks much to anyone that can help. | | , 17.06.2011 Thanks to Cananda and Australia for partnering with us. | | Ed Madigan, madigan21=hotmail.com, 05.05.2011 After coming from B-52's in Sac, flying the bou in Nam was a real treat. Got an airplane in the morning you could strap on and have some fun with. Serving the Army was a pleasure and an honor. Got to work with the 5th Special Forces in the Delta, air land and air drop supplies. Good airplane, great crews and a damn rewarding mission. 536th TAS 67/68 Vung Tau RVN | | Joseph Tedeschi, tedeschij=comcast.net, 10.04.2011 Was one of fortunate survivors of crash of C-7 into Hong Kong Mountain at An Khe on 4 Oct 1966. Thirteen were killed including air crew. Blinding fog and we flew right into mountain. Tree took off right wing and we augered in upside down. No explosion or fire. This tough airplane saved my life. I was med-evaced with broken hip, and never got to know full story and details of crash. Anyone have any info? | | Rodger Harrington, rkharrin1=att.net, 11.03.2011 I was lucky enough to have been crew chief on one of the caribous (AC-1) that comprised the 187th Trans Airplane Company,11th Air Assault at Ft. Benning tail number 62-4155. Spent many hours flying accross the state at tree top level from Benning to Camp Stewart developing low level flight concept to be used in Nam. I have been able to find a program for my flight simulator from AlphaSim that is almost identical to the aircrafts performance, sounds and replicates everything from the cock-pit to the loading ramp. I still have many fond memories of that time in my life. It was trully a great aircraft that proved itself and I can see why the Air Force did not enjoy competing with the Army and ended up taking it as one of its own. | | Joseph W. Hazen, tokyojo=comcast.net, 05.03.2011 I flew the Caribou for Air America in Southeast Asia, mostly Laos, from August 1962 to April 1966. A very reliable and comfortable aircraft. In one 7 day period, I made 115 takeoffs and landings, 37 the most in one day. I bet that is a record. | | pete castillo, petecastillo26=yahoo.com, 21.02.2011 I was assigned to the 483rd TAW between Oct '68 thru Oct 69. My job mainly consisted of loading and off-loading the C7A during the morning. The Bou would then fly on to Vung Tau and back to home base. Loved to be part of history. Msgt Pete Castillo TX 92nd AFJROTC Eagle Pass,TX | | pete castillo, petecastillo26=yahoo.com, 21.02.2011 I was assigned to the 483rd TAW between Oct '68 thru Oct 69.

Msgt Pete Castillo TX 92nd AFJROTC Eagle Pass,TX | | Dave Sandelin, openboxvalue=att.net, 04.02.2011 I was an ARDF operator on a Caribou in Vietnam '66-'67. It was called the Pathfinder, as we had innovative equipment that was being proven, and which was added to later aircraft. The thing could land on a dime, and give you nine cents change. W/O John (Big John) Brazil was the pilot, and between his skill and the wonderful design of the Caribou, I loved the plane. | | Jerry Pankonen, cariboupilot=yahoo.com, 10.11.2010 I was part of the initial cadre of Air Force (AF) pilots that replaced Army pilots at Vung Tau from late August of 1966. AF headquarters rushed to find anyone from desk jockey to jet pilot to fill the Caribou crew member slots. This pot-pourri of pilots were sent to Ft Benning to be trained by the Army; then to jungle survival, and for me on to Vung Tau, Vietnam to fight the war. Luck of the draw to get Vung Tau, an in country R and R location for the GI's and Viet Cong. One hell of a great experience to fly, train and live (until they kicked us out) with Army Warrant Officers. I transitioned from the fast T-38/C-141 to the very slow Bou. Army taught me to stop my descent when I saw the tops of trees; radio beacon timed precision approaches; and special VFR approaches to Saigon in IFR conditions. Ahhh yes those were the good old days. Learned to love the caribou. It took hits and just kept on going. Many great memories of the Bou, the guys that flew them, flight mechs/load masters, and the maintenance guys. We were all in this mess together and made the best of a bad situation. A one of a kind experience for me and one that I would not trade for anything. |
