"The Chinook is an awesome aviation airframe. It is able to lift single heavy-duty pieces of equipment and light vehicles and is one of the most reliable airframes in service in the entire United States Military. It can lift up to 50,000 pounds and nearly 26,000 can be slung below the helicopter from the center hook. It has redundancy built in that many people do not even realize, which makes it a very safe airframe. Each of the huge rotor blades on the Chinook CH-47 weighs 350 pounds, and the engines work together to turn the rotors. Each of the engines work about 50 percent capacity, if one engine fails the other simply goes into high gear, and functions at 100 percent allowing the helicopter to fly just as well as it does with two engines." - Military.com The CH-47 is a twin-engine, tandem rotor helicopter designed for transportation of cargo, troops, and weapons during day, night, visual, and instrument conditions. Development of the medium lift Boeing Vertol (models 114 and 414) CH-47 Series Chinook began in 1956. Since then the effectiveness of the Chinook has been continually upgraded by successive product improvements, the CH-47A, CH-47B, CH-47C, and CH-47D. The amount of load a cargo helicopter can carry depends on the model, the fuel on board, the distance to be flown, and atmospheric conditions. The CH-47D shares the same airframe as earlier models, the main difference being the adoption of more powerful engines. Early CH-47Ds were originally powered by two T55-L-712 engines, the most common engine is the later T55-GA-714A. With its triple-hook cargo system, the CH-47D can carry heavy payloads internally and up to 26,000 pounds (12 t) (such as 40-foot or 12-metre containers) externally. It was first introduced into service in 1979. In air assault operations, it often serves as the principal mover of the 155 mm M198 howitzer, accompanying 30 rounds of ammunition, and an 11-man crew. The CH-47D also has advanced avionics, such as the Global Positioning System. Nearly all US Army CH-47D were conversions from previous A, B, and C models, a total of 472 being converted. The last U.S. Army CH-47D built was delivered to the U.S. Army Reserve, located at Fort Hood, Texas, in 2002. The Netherlands acquired all seven of the Canadian Forces' surviving CH-147s and upgraded them to CH-47D standard. Six more new-build CH-47Ds were delivered in 1995 for a total of 13. The Dutch CH-47Ds feature a number of improvements over U.S. Army CH-47Ds, including a long nose for Bendix weather radar, a "glass cockpit", and improved T55-L-714 engines. As of 2011, the Netherlands shall upgrade 11 of these which will be updated to the CH-47F standard at a later date. As of 2011, Singapore has 18 CH-47D/SDs, which includes twelve "Super D" Chinooks, in service. In 2008, Canada purchased 6 CH-47Ds from the U.S. for the Canadian Helicopter Force Afghanistan for $252 million. With 1 CH-47D loss, the remaining 5 CH-47D were returned by Canada in 2011 after their mission in Afghanistan was over. Pictured here is a

"Petawawa" - No.450 Tactical Helicopter
Squadron is a Royal Canadian Air Force helicopter squadron. During the
Second World War, the numerical designation of 450 was originally given
to No.450 Squadron of the Royal Australian Air Force, which flew under
that number from 1941 until 1945 in the Middle East and Italy. Canadian
Article XV squadrons during the Second World War had used numbers from
400 to 449; however, due to an administrative error, the "450"
designation was used when squadron formed at RCAF Station St. Hubert,
Quebec, on March 29th, 1968.
The squadron moved to CFB Ottawa (Uplands) in May 1970 and the squadron
received Royal Assent for the designation 450 Transport Helicopter
Squadron on May 20th, 1970. On August 1st, 1991, the squadron was
re-designated 450 Composite Helicopter Squadron. This was followed by
another name change on April 1st, 1993, when the squadron became 450
Tactical Helicopter Squadron. In August the following year, 450 Tactical
Helicopter Squadron was transferred back to 1 Wing at St. Hubert.
450 Squadron was deactivated in 1996 before being officially disbanded
on January 1st, 1998. On May 2nd, 2012, the squadron was re-established
to operate the CH-147F Chinook helicopters of the Royal Canadian Air
Force, based out of CFB Petawawa. Please
