About

The North American Mustang is often called the finest fighter of the war, and the transformation that made it so was British. Designed in 1940 to a British purchasing requirement, the early Allison-engined Mustang reached the RAF in 1942 as a fast, long-ranging low-level reconnaissance and fighter-bomber aircraft — excellent down low, but lacking performance at altitude.

The breakthrough came when Rolls-Royce engineers at Hucknall fitted the Mustang with the Merlin engine. The combination of the Merlin’s high-altitude power with the Mustang’s clean airframe and large fuel capacity produced a fighter that could escort heavy bombers all the way to Berlin and back. American-built Packard Merlins powered the production P-51B and later marks; the RAF flew around 1,500 Merlin-Mustangs (as the Mustang III and IV) on daylight operations, while the type became the USAAF’s decisive long-range escort over Germany.
