These technicians are fitting the V12 Merlin engine at the Castle Bromwich Aircraft Factory. The engine - which produced 1030hp - was able to power the Spitfire to 362mph - 30mph quicker than the Hurricane equipped with the same engine.

Rolls-Royce Made in the U.S.A. Packard Merlin Engine. When the Merlin crossed the Atlantic, it got an American makeover. Packard, the luxury car maker building it, didn't just copy the design. They re-engineered it for mass production. A key upgrade was hidden deep inside: the crankshaft bearings. They swapped Rolls-Royce's alloy for a superior silver-lead combination, a secret recipe from General Motors, making the engine tougher and more reliable under the strain of combat.
