The aircraft was designed to accommodate a three-man crew and a payload of 12 bombs. In addition to the pilot's cockpit, which was positioned just ahead of the wings, there were two positions for gunners, one behind the wings and the other in the nose, each with a pair of Scarff ring-mounted Lewis guns; the rear cockpit mounting was commonly not fitted during the interwar period. Provision for a maximum of four spare drums of ammunition were present in the nose position, while up to six drums could be carried in the rear position.
