The Sopwith Two Seater, as it was officially known, was universally referred to as the Sopwith One-and-half Strutter.  The nickname derives from the ‘w’ shaped center section struts.

It was a landmark design in WW1, the first tractor two-seater fighter and the first British fighter to have a synchronized Vickers machine gun for the pilot.  Deliveries of the aircraft to the RFC began in May1916.  The RFC was in desperate need of a good fighter at this time and many Naval Sopwith One-and-half Strutters were transferred to the RFC.  1500 were made in the UK and 4500 were made under license in France.   It was also used by the USA, Belgium and Russia.

In the manner of aerial fighting in WW1, it was the dominant fighter for only six months as the new Albatros Scouts that appeared in September proved superior.  Fortunately, by this time, a smaller more agile derivative was in production, the Sopwith Scout, known universally as the Sopwith Pup because it was seen (correctly) as the son of the Sopwith One-and-half Strutter.

The leading ace in the aircraft was Captain Geoffrey Cock MC who scored 13 victories on type.
