This beautiful image shows a WWII era Spitfire starting its V-12, 27-litre (1,650 cubic inch) Merlin engine.
The Merlin was (arguably) the most successful aircraft engine of World War II – variants were built by Rolls-Royce in Derby, Crewe and Glasgow, as well as by Ford of Britain at their Trafford Park factory, in the north of England. The Packard V-1650 was a clone of the Merlin built in the USA – it was fitted to the North American P-51 Mustang as a replacement for the poorly performing Allison V-1710 engine.
The North American P-51 Mustang was transformed by the addition of the British engine and saw a significant boost in power, high-altitude performance and speed.
