The Republic XP-69 (Model AP-18) was designed as a fast high altitude fighter capable of intercepting and destroying high altitude enemy bombers. The XP-69 was planned to incorporate recent technological innovations such as a pressurized cabin, laminar flow wing, and contra-rotating propellers. The aircraft was designed to take advantage of the recently developed Wright R-2160 42-cylinder engine, a radical design thought to be the highest rated engine then available for pursuit aircraft. When the new engine ran into development problems and production delays, the Army Air Corps canceled the contract in favor of the Republic XP-72
