Curtiss B-2 Condor

https://en.wikipedia.org/wiki/Curtiss_B-2_Condor

The Curtiss B-2 Condor was a 1920s United States bomber aircraft. It was a
descendant of the Martin NBS-1, which was built by the Curtiss Aeroplane and
Motor Company for the Glenn L. Martin Company. There were a few differences,
such as stronger materials and different engines, but they were relatively
minor.

The B-2 was a large fabric-covered biplane aircraft. Its two engines sat in
nacelles between the wings, flanking the fuselage. It had a twin set of rudders
on a twin tail, a configuration which was becoming obsolete by that time. At the
rear of each nacelle was a gunner position. In previous planes, the back-facing
gunners had been in the fuselage, but their view there was obstructed. A similar
arrangement (using nacelle-mounted gun platforms) was adopted in the competing
Keystone XB-1 aircraft.

The XB-2 competed for a United States Army Air Corps production contract with
the similar Keystone XB-1, Sikorsky S-37, and Fokker XLB-2. The other three were
immediately ruled out, but the Army board appointed to make the contracts was
strongly supportive of the smaller Keystone XLB-6, which cost a third as much as
the B-2. Furthermore, the B-2 was large for the time and difficult to fit into
existing hangars. However, the superior performance of the XB-2 soon wrought a
policy change, and in 1928 a production run of 12 was ordered.

One modified B-2, dubbed the B-2A, featured dual controls for both the pilot and
the copilot. Previously, the control wheel and the pitch controls could only be
handled by one person at a time. This "dual control" setup became standard on
all bombers by the 1930s. There was no production line for the B-2A. The B-2
design was also used as a transport.

The B-2 was quickly made obsolete by technological advances of the 1930s, and
served only briefly with the Army Air Corps, being removed from service by 1934.
Following production of the B-2, Curtiss Aircraft left the bomber business, and
concentrated on the Hawk series of pursuit aircraft in the 1930s.
