The United States impressed 10 North American NA-69 attack aircraft ordered by Thailand when it became apparent the aircraft would fall into Japanese hands in the early 1940s. The United States was not yet at war with Japan at this point. The NA-69 was basically an attack version of the AT-6 trainer aircraft intended for export.
The aircraft were re-designated A-27s and given 1941 serial numbers. The A-27s were assigned to the U.S. Army Air Corps' 17th Pursuit Squadron at Nichols Field in the Philippines. When the Japanese attacked the Philippine Islands in the first days of the Pacific War, all A-27s were destroyed.
