The P-51 Mustang was a solution to the clear need for an effective bomber escort. The Mustang was at least as simple as other aircraft of its era. It used a common, reliable engine and had internal space for a huge fuel load. With external fuel tanks, it could accompany the bombers all the way to Germany and back.
However, the Allison engine in the P-51A had a single stage supercharger that caused power to drop off rapidly after 15,000 ft. This made it completely unsuitable for combat at the altitudes USAAF bombers planned to fly.

Following the RAF's initial disappointing experience with the Mustang 1 (P-51A) Ronald Harker from Rolls Royce suggested fitting a Merlin 61, as fitted to the Spitfire Mk IX. The Merlin 61 had a two speed two stage intercooled supercharger, designed by Stanley Hooker of Rolls Royce and this gave an increase in horsepower from the Allison's 1,200 to 1,620 (or 1,720 in War Emergency Power) an increase of top speed from 390 mph to 440 mph as well as raising the service ceiling to almost 42,000 ft.
Initial flights were completed October 1942 and a similar conversion then took place in the US, leading to production of the P-51B beginning at North American's Inglewood California plant in June 1943 and P-51s started to become available to the 8th and 9th Air Forces in the winter of 1943–1944.
