The XP-72 was a more-or-less straightforward progressive development of the P-47 Thunderbolt, designed to be a successor for that very successful aircraft. With a 3450 hp engine, a maximum speed of 500mph was hoped for. After favorable testing of the prototype, the USAAF ordered 100 examples, though the contract was cancelled with the changing course of the war. Only the two prototypes were built, one of which crashed, and the other was eventually scrapped.
