In the civilian sector, the Beaver soon excelled on wheels, skis, and floats, and in 1951, the Beaver was selected by the US Air Force and Army as a new liaison aircraft. In the nine years that followed, 968 L-20As were delivered to the armed forces, most going to the Army. They served in both the Korean War and Vietnam War, hauling freight and personnel around the battlefields, mapping enemy troop positions, leading search/rescue missions, and relaying radio traffic, among other missions. In 1962, the L-20 was redesignated the U-6A, and many examples remained in service well into the 1970s. Beavers were also purchased and used by the military services of numerous other nations, including Britain, Chile, and Colombia.
