B-18 Bolo

The Douglas B-18 Bolo bomber served with the United States Army Air Corps and the Royal Canadian Air Force (as the Douglas Digby) during the late 1930s and early 1940s. The Bolo was built by Douglas Aircraft Company and based on its DC-2 and was developed to replace the Martin B-10.

By 1940 it was considered to be underpowered, to have inadequate defensive armament and carried too small a bomb load. Many were destroyed during the attacks on Pearl Harbor and the Philippines in December 1941.

In 1942 the B-18 survivors were relegated to antisubmarine or transport duty.
