Formed in 1906 to first produce automobiles, Rolls-Royce was asked to begin designing and building aircraft engines at the outbreak of World War I in 1914. The famous Rolls-Royce Merlin, which followed the similar Kestrel design, powered many significant aircraft of World War II, including the Hawker Hurricane, Supermarine Spitfire, and North American P-51. Design of the Merlin began in 1933, which had helped pioneer high-output, liquid-cooled engines throughout the 1920s and '30s.
The most powerful versions of the Merlin developed more horsepower for their displacement than any other production engines of World War II. The Packard Motor Car Company and Continental Aircraft built over 58,000 Merlins in the United States under license. Many were shipped to England, and others were used in versions of the Curtiss P-40 and most versions of the P 51. This artifact of the Packard-built Merlin powered various models of the North American F-6 and P-51 Mustang.
