This heritage pamphlet from Malmstrom AFB traces the history of the 341st Missile Wing. The unit began as a B-25 bomb group in the China-Burma-India Theater in 1942, then flew B-47s at Abilene AFB before being activated at Malmstrom in July 1961. The pamphlet covers the Minuteman I, II and III deployments, the Cuban Missile Crisis alert, arms-reduction work under START, trophies, wing commanders and a missile field chronology. It also has museum display notes on missiles and the UH-1 helicopter.
341st Missile Wing History BEECH AT-11 KANSAN The AT-11 was the standard U.S. Army Air Forces World War II bombing trainer; about 90 percent of the more than 45,000 USAAF bombardiers trained in AT-11s. Like the C-45 transport and the AT-7 navigation trainer, the Kansan was a military version of the Beechcraft Model 18 commercial transport. Modifications included a transparent nose, a bomb bay, internal bomb racks and provisions for flexible guns for gunnery training. Student bombardiers normally dropped 100- pound sand-filled practice bombs. In 1943 the USAAF established a minimum proficiency standard of 22 percent hits on target for trainees. Typical combat training missions took continuous evasive action within a 10-mile radius of the target with straight and level final target approaches that lasted no longer than 60 seconds. After Sept. 30, 1943, the AT-11 usually carried a Norden Bombsight and a C-1 automatic pilot, which allowed the bombardier student to guide the aircraft during the bombing run. The AT-11 on display is one of 1,582 ordered by the USAAF between 1941 and 1945, 36 of which were modified as AT-11A navigation trainers. It was donated to the museum by the Abrams Aerial Survey Corp., Lansing, Mich., in 1969, and is painted to represent a trainer in service during the autumn of 1943.
