Design and development
During assembly, the second prototype XO-27 was converted to a bomber prototype, dubbed the XB-8. While the XB-8 was much faster than existing biplane bombers, it did not have the bomb capacity to be considered for production. Two YB-8s and 4 Y1B-8s were ordered, but these were changed mid-production to Y1O-27 configuration.
The wing of the XB-8 and XO-27 was built entirely from wood, although the fuselage was constructed of steel tubes covered with fabric with the exception of the nose which had a corrugated metal.[1] They featured the first retractable landing gear ever fitted to an Army Air Corps bomber or observation craft. The undercarriage retracted electrically. Crew was three in tandem position.[1]
Operational history
It competed against the Douglas Y1B-7/XO-36. Both promised to greatly exceed the performance of the large biplane bombers then used by the Army Air Corps. However, the Douglas XB-7 was markedly better in performance than the XB-8, and no further versions of Fokker's aircraft were built.

Die Fokker O-27 (Atlantic-Fokker Model 16) war ein als leichtes Beobachtungs-, Bomben- und Luftnahunterstützungsflugzeug vorgesehener Entwurf des US-amerikanischen Herstellers Fokker Aircraft Corporation of America, der Anfang der 1930er Jahre für das United States Army Air Corps (USAAC) gebaut wurde. Die O-27 wurde jedoch lediglich als Schulflugzeug eingesetzt. Nachdem im Mai 1929 General Motors eine 41-prozentige Beteiligung an der Fokker Aircraft Corporation of America erworben hatte und ein Jahr später das Unternehmen in General Aviation Corporation (GAC) umbenannt worden war, erfüllte die GAC die Produktionsverpflichtungen von Fokker.- [en] Fokker XB-8
