The "What is it?" aircraft in our last issue was a Douglas B-7 bomber of the early 1930s.
This series of twin-engined aircraft, powered by 600-hp. Curtiss V-1570 Conqueror engines, began as an observation plane and became a bomber only belatedly. Air Power History is grateful to Robert Taylor Robert Taylor or Bob Taylor may refer to:
The Army Air Corps ordered two aircraft in this series on March 26, 1930--an XO-35 (30-227) and an XO-36 (30-228). They had variations of the V-1570 engines, with differing nacelles and propellers.
Because of the high performance of these gull-winged planes, the Army decided to employ the type as a light bomber Light bomber is a relatively small and fast class of military bomber aircraft which was employed mainly before the 1950s. Such aircraft would probably not carry more than one ton of ordnance. . One of the prototypes was redesignated the XB-7.
In August 1931, the Air Corps ordered seven Y1B-7 bombers (32-308/314) and five Y1O-35 observation craft (32-315/319). The "Y" prefix signified a service test role. The photo in our last issue, taken by Boardman C. Reed in about 1937, showed a Y1B-7 in a temporary camouflage scheme at pastoral Mines Field, California, site of today's Los Angeles International Airport “LAX” redirects here.

The seven Y1B-7s served briefly with the 11th and 31st Bombardment Squadrons at March Field, California. It was the Army's first monoplane monoplane: see airplane. bomber to enter service.

The B-7 was a relatively advanced aircraft for its day, but could not compete as changes in technology came swiftly. Among them was the Martin B-10 all-metal bomber that was faster than most fighters of its era.
Our follow-up photo depicts the third Y1B-7 bomber (32-310) in September 1933, at the site of the present-day Boeing Field in Seattle, and was taken by Gordon S. Williams.
