In 1940, Tucker formed the Tucker Aviation Corporation, with the goal of manufacturing aircraft and marine engines. The corporation (Tucker's first) was initially based at his shop behind his Michigan home. A public corporation with stock certificates issued, Tucker raised enough to develop the design for a fighter aircraft, the Tucker XP-57, which earned the interest of the United States Army Air Corps (USAAC). Development of a single prototype of the airplane was started, powered by a straight 8-cylinder engine developed/influenced by Harry Miller, called the Miller L-510. Nicknamed the "Peashooter", this fighter competed for WWII government war contracts. However, financial problems within the company slowed the development of the prototype and the USAAC allowed the contract to lapse.
