Fokker USA O-27 / B-8

 

1st Flight 1929
In the late 1920s, the U.S. Army Air Corps became interested in acquiring high-speed front-line scouts.
Fokker O-27 / XB-8
One of the results of this was the O-27, commissioned by Fokker Aircraft, which in September 1925 became known as Atlantic Aircraft.
The three-seater O-27 had a typical “Fokker” design – with fuselage and plumage, welded from steel pipes and lined with cloth, as well as a wooden wing with plywood cladding.
From other Fokker aircraft of that period, it differed from the location of the pilot’s cockpit over the wing and the chassis design.
Two prototypes under the XO-27 index were ordered.
The second prototype under the new designation XB-8 was built with an elongated nasal compartment and equipped with suspensions for attaching bombs.

In 1931, six YO-27s and six YB-8s were ordered for combat tests.
All 12 aircraft were built as surveillance aircraft.
The vehicles ordered under the YB-8 designation were called Y1O-27.
The O-27 aircraft (as they were all renamed later) differed from the prototype by closed cockpits and improved tail plumage.
In the nasal compartment there was an open cockpit of the flight shooter and a glazed navigator’s seat under it.
The second open cockpit of the flight was at the top of the fuselage.
In 1932, the XO-27 aircraft were equipped with Curtiss V-1570 gearbox and named XO-27A.
The O-27 served for several years in the front line of the U.S. Army Air Corps.
