Rejected 3 Times — Then It Saved The Entire Bomber Campaign

Added: 2026-06-03

The P-51 Mustang, initially rejected by the US Army Air Corps and limited by its Allison V-1710 engine's high-altitude performance issues, was transformed into a bomber escort champion when British engineers installed the Rolls-Royce Merlin 61 engine, achieving speeds over 440 mph and extending its combat radius to 880 miles, which dramatically reduced USAAF bomber losses and saved the strategic bombing campaign.
