One of the Air Historic Branch aircraft, displayed at the Biggin Hill Station Museum in RNAS colours. Current in the RAF Museum Hendon in 2020. Date is approximate.

The Triplane was briefly succesful with a couple of British and French naval fighter squadrons early in 1917, but had structural and maintenance issues, and was armed with one machine gun only. The Fokker Dr.I was developed in response.

The prototype Triplane first flew in May 1916 and the type entered service with the Royal Naval Air Service early in 1917 and a total of 147 were built. It was a very agile but lightly armed type that was soon superceded by the biplanes. Often quoted as cn 8385M, but that is its allocated RAF maintenance serial.
