In 1940, the USAAF changed the designation to AT or advanced trainer, so the American machine became the AT-6. The U.S. Navy version was called the SNJ.Even with their huge new 2,000,000 square foot plant, North American couldn't keep up with the wartime demand so a new factory was built in Dallas, leading, after 1942 to the AT-6 being called the "TEXAN".
Beginning in January, 1940 The HARVARD MkIIB version was built under license by NOORDYN of Montreal, Canada for the Royal Canadian Air Force, the RAF and the USAAF. Ultimately 2,557 Harvards were built here.
