Douglas Y1B-7

The Douglas Y1B-7 was a 1930s United States bomber aircraft. It was the first US monoplane given the B- 'bomber' designation. The monoplane was more practical and less expensive than the biplane and the United States Army Air Corps chose to experiment with monoplanes for this reason. At the time the XB-7 was ordered it was being tested by Douglas Aircraft as an observational plane.
