Vickers F.B.9

The Vickers F.B.9 was a development of the Vickers F.B.5 with rounded wing-tips, a vee undercarriage, and extra room in the nose for the gunner's legs. The early models featured a rounded D-shaped nose, but later models extended the bottom fuselage further. Most F.B.9s went to training units. , but the first had gone to France for operational testing in January and several others were shipped over in May-June 1916 where they served over the Battle of the Somme. By 21 July 1916, they had all been withdrawn, so their operational lifetime was brief.

Around 75 were delivered as trainers, a role they played into 1918.
