P-51D

The P-51 Mustang was a single-seat, single-engine fighter aircraft developed by North American Aviation for the British Royal Air Force and later adopted by the U.S. Army Air Forces during World War II. It is widely considered the finest all-around piston-engined fighter of the war produced in significant numbers.1

Initially powered by an Allison engine, the Mustang excelled at low altitudes but lacked high-altitude performance due to its engine's supercharger limitations. However, when fitted with a Rolls-Royce Merlin engine, the P-51 gained outstanding high-altitude capabilities. This Merlin-powered version, particularly the P-51D variant, became crucial for escorting Allied bombers over Germany, significantly reducing bomber losses and contributing to the defeat of the Luftwaffe. The P-51D featured a bubble canopy for improved visibility and was armed with six .50-caliber machine guns, with additional hardpoints for bombs or rockets.1
