The Gun Bus was essentially a landplane derivative of the S.P.Gn (Sopwith Pusher, gun. The Gun Bus, intended for the fighting role, carried a 7.7mm machine gun on a flexible mount in the forward cockpit and was powered by a 100hp Gnome Monosoupape rotary engine. A more powerful version, with a 150hp Sunbeam eight-cylinder water-cooled engine, was developed specifically for the RNAS, this having a redesigned nacelle and a revised undercarriage. Six of the Sunbeam-powered Gun Buses were built for the RNAS by Sopwith, a further 30 being ordered for the service from Robey & Company, these last being intended for bombing (and possibly anti-submarine) duties as distinct from fighting. The pilot was moved forward to the front cockpit, a bombing panel being let into the floor and four bomb carriers being fitted beneath the lower wing.
