26 November 1913

The Vickers E.F.B.2, designed by Archibald Low, made its first flight at Brooklands on 26 November 1913. This two-bay biplane, a progenitor of the F.B.5 "Gun Bus", was powered by an 80 hp Gnome Monosoupape rotary engine. It had a steel tube structure, fabric covered wings and tail, and a duralumin covered nacelle. Armament was a single Vickers gun mounted in the nose of the nacelle, with limited movement possible, and a very poor view for the gunner.
