The BR.2 was built in small numbers during the war, its main use being by the Royal Air Force in the early 1920s.

A number of other experimental and minor production types were either designed for, or otherwise fitted with this power plant during the late "war" years and into the early 1920s.

Another one (serial number 40543, manufactured by Gwynnes) is in the National Military Museum, Romania.

The sole operational BR.2 is mounted in Fantasy of Flight's replica of the Sopwith Snipe.
