C.Barnes Bristol Aircraft since 1910 (Putnam)

One other Bristol biplane, the S.2A, deserves notice here, although it was a two-seater. It was derived from the Scout D and was designed to meet an Admiralty specification for a two-seater fighter. Powered by a 110 h.p. Clerget rotary engine installed between horizontal bearers as proposed for the G.B.l, it had the same tail surfaces as Scout D but less rake at the wing tips. Two seats were installed side by side in the single cockpit. The design was rejected by the Admiralty, who preferred the Sopwith 1 1/2 Strutter, but the War Office were interested in it as a potential advanced trainer and ordered two prototypes on 10 March 1916. These, Nos. 1377 and 1378 (7836 and 7837), were built and flown in May and June 1916, being delivered to the Central Flying School at Upavon on 11 June and 30 July, respectively. One of them was later flown at Gosport, where it had been fitted with a 100 h.p. Monosoupape-Gnome in a modified cowling. Its performance was quite good in spite of its girth, which earned it the nickname 'Tubby' at Filton as well as other appropriate epithets at the C.F.S.

H.King Armament of British Aircraft (Putnam)

S.2A. This 1916 development of the Scout, designed for the Admiralty, had side-by-side seating and was intended for fighting. The proposed armament was a Lewis gun, possibly on a pillar mounting behind the cockpit.

  A derivative of the Scout D intended to meet an Admiralty specification for a two-seat fighter, the S.2A had side-by-side seating and was intended to be armed with a single 0.303-in (7,7-mm) Lewis gun. In the event, it was rejected by the Admiralty in favour of the Sopwith 1 1/2 Strutter, but work continued on the two prototypes at the behest of the War Office which envisaged the type primarily as a potential advanced trainer for the RFC. The two prototypes were completed in May and June 1916 respectively, being powered by the 110 hp Clerget engine (although one was later re-engined with a 100 hp Gnome Monosoupape), and were delivered to the Central Flying School at Upavon. They were found to be manoeuvrable and quite fast, but no further development was undertaken.

W.Green, G.Swanborough - The Complete Book of Fighters
Bristol's S.2A featured unusual side-by-side seating, but only a single Lewis gun armament.
The Bristol S.2A, actually 7836, which differed from the 7837 (which was the only other one) by the shape of the cockpit cut-out as well as the engine. It was a 2-seater with side-by-side seating, and was sometimes referred to as the "sociable"; also as the "tubby". Intended as a fighter, it got a little use as a trainer.

First S.2A 7836 at Filton in June 1916.

The two seat Bristol S 2A fighter, a derivative of the Bristol Scout D was unusual in that it had the pilot and gunner placed side-by-side. Built originally to an Admiralty requirement, the first of the two built, serial no 7836 seen here, first flew in May 1916. Using a 110 Clerget, or 100 Gnome Monosoupape, the S 2A had a top level speed of 95mph at sea level. While not pursued as a fighter, both S 2As went on to serve as advanced trainers with the Central Flying School.
