<hi style=afpcap>The Curtiss AT-9 was designed as a twin engined pilot transition trainer. A total of 491 AT-9s were built along with 300 AT-9As, although their service career was fairly short-lived as they were phased out in favour of more versatile trainer aircraft capable of full crew integration training. </hi>
