The P-51 was an American built fighter aircraft from World War 2
Original designed to a British specification with an Allison engine, it really came into it's own when fitted with a Rolls Royce Merlin Engine. The P-51D was the first version with a bubble canopy and cut down rear fuselage. The top speed was about 440mph, and a maximum altitude of 41,000ft. With external fuel tanks, it had a range of 1650miles.
