The story
The U-21 Ute grew out of a 1963 experiment: Beechcraft hung PT6 turboprops on a Queen Air, and that proof of concept led to the King Air. The Army bought U-21s for staff transport, cargo and medevac, plus RU-21 versions packed with radio direction-finding gear that served in Vietnam. The Army retired the type in January 2000 and many went to civil operators, so survivors usually wear civilian paint.
Like most Army aircraft it is named after a Native American people, and its prototype flew in May 1963, months before the first King Air.
