The P-51 Mustang was a long-range World War II fighter aircraft that flew as a bomber escort over Germany. Powered with the British Rolls-Royce Merlin engine, it was unmatched by any other piston fighter aircraft of World War II.
Originally produced by McDonnell Douglas, this Boeing twin-engine army attack helicopter first entered service with the US Army in 1984. Since then it has become the primary attack helicopter of many nations. More than 2,000 have been produced.
This American tandem rotor, heavy-lift helicopter was first used during the Vietnam War. Powered by two 4,733 horsepower turbo-shaft engines, it has a top speed of 196 mph which made it faster than any other utility and attack helicopter at that time. It remains in production and frontline service, with over 1,200 built to date.
