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.

Australian International Airshow 2011

1 March 2011 00:00 to 6 March 2011 00:00

The Royal Australian Air Force (RAAF) is planning to make the 2011 Australian International Air Show a centrepiece of RAAF’s 90th anniversary activities, Chief of Air Force, Air Marshal Mark Binskin announced today.

The Air Show at Avalon next March will be one of the largest and most comprehensive air shows ever conducted in the Southern Hemisphere.

“The air show will coincide with RAAF’s 90th Anniversary. So the 90th will be a key theme for this world class event which is run by Air Shows Down Under,” Air Marshal Binskin said.

“This will be a great opportunity for the public to get a close look at Air Force’s current high-tech fighter and strike capabilities, including the potent F/A-18F Super Hornet and the Wedgetail airborne early warning and control aircraft, both of which came into RAAF operational service this year.”

The air show will be a major opportunity to highlight RAAF’s future, in particular our transition to the cutting-edge Joint Strike Fighter,” Air Marshal Binskin said.

“The Avalon air show and associated conferences will also focus on unmanned aircraft. Air Force’s Heron is already providing crucial support to operations in Afghanistan, and remotely piloted aircraft will be a key feature of our future capability.”

“We anticipate nearly all of Air Force’s aircraft types will be represented at Avalon next year, along with Navy and Army aviation assets. Dozens of Australian Defence Force aircraft will participate. We’re also planning major displays of the ADF’s ground-based equipment and capabilities.”

“The Australian International Air Show is a key opportunity for Defence to engage our industry partners. The air show and conferences will also draw senior military personnel from the Asia Pacific region and across the world. This makes it an ideal forum to meet and exchange ideas with our international military counterparts,” Air Marshal Binksin said.
