Before there was an AT-11, there was Beech Aircraft Company
of Wichita, Kansas. For decades, the nickname “Beechcraft” applied
to all Beech designs, starting with the Model 18, which flew for the first time in January 1937. The 18 was soon nicknamed the “Twin Beech.”
First flights were made by TWA pilots James N. Peyton and Jack Thornberg. Peyton noted, “This aircraft was outstanding in its class.
It exceeded all its estimated performance figures.” Thornberg said,
“The ‘Twin Beech’ was the greatest airplane of its kind I have ever flown.”
In 1939, the Republic of China ordered 20 Beech 18s modified
to serve as bomber trainers equipped with clear plastic noses,
a gun turret on the top of the fuselage, and a machine gun mount
placed in the floor of the rear fuselage. The modifications included
a bomb bay, which held up to twenty 25 lb bombs.
The first US military orders for the type (designated C-45) were placed in 1940. In 1941, General Henry (“Hap”) Arnold visited the
Beech aircraft factory and placed the first order for trainer versions
of the aircraft to be used by the US Army Air Forces (USAAF).
Using the same basic airframe other US versions were
manufactured for the USAAF as the AT-7 Navigator, C-45
Expeditor, F-2 (reconnaissance), the US Navy as the JRB
(transport) and SNB (trainer). Military forces, including those
of Canada, Turkey, The Netherlands, China and US, purchased
5,204 examples of the type.
Most US-trained pilots, bombardiers, air gunners and navigators flew AT-11s before joining operational units.
Of the 1,178 built during World War Two, fewer than 10 AT-11s fly
today in their original configuration.
