[3] The first of the Greek Pusher Seaplanes flew in February 1914, successfully passing trials in March, with first deliveries in May and all six delivered by the outbreak of the First World War.
[2] While the Greek machines performed well, despite the limited facilities available at their base at Eleusina, with at first no workshops or hangars available,[3] the two British aircraft were less successful, with their engines proving unreliable, and were withdrawn by February 1915.
[2] In March 1914, the Greeks placed an order for six more pusher seaplanes, the Sopwith S PG N, which were similar to their previous aircraft, but rather than being dual control trainers, were to be armed with a machine gun in the nose, and powered by a Gnome Monosoupape rotary engine.
[3] At least five of these aircraft were taken over by the Royal Navy at the outbreak of war, but again proved unsuccessful in British Service, with at least two being modified as landplanes.
[2] The Royal Navy ordered six modified landplane based on the S PG N in July 1914, the Sopwith Gunbus or Admiralty Type 806, to be powered by 110 hp (82 kW) Sunbeam water-cooled V8 engines and armed with a machine gun.
