The
prototype civilian Cessna 310 first flew in 1954. In
1957, the U.S. Air Force selected the aircraft for light
administrative liaison and utility duties, designating it the L-27.
In 1962, the aircraft was re-designated the U-3.
Popularly known as the "Blue Canoe", the
U-3 was used by the U.S. Air Force and U.S. Army.
