|Beech's Model 18 civil transport was developed during the Second War in a number of forms for the military, initially as the C-45 light transport. The AT-7 Navigator was ordered in 1941 as a navigation trainer version with an astrodome, chart tables and instruments for three trainees. Production totaled 577 AT-7s with 450-hp R985-25 radials, six AT-7s float plane, nine winterized AT-7Bs and 549 AT-7Cs with higher weights. Another 1941 version was the AT-11 Kansan gunnery and bombing trainer. This has a small bomb bay, a glazed nose with bomb sight, and two machine guns, one in the nose and the other in a dorsal turret. Production for US use totaled 1,582 of which 36 were modified to AT-11A navigation trainer, and other were converted as C-45G and C-45H transport. After the war, the AT-11 and AT-11A became T-11 and T-11A respectively, the latter then being modernized to T-11B standard as well as the above planes the US Army possessed 24 AT-11s originally built to satisfy an order from the Netherlands.|
