The seaplane, manufacturers serial number S.81, was built at Eastchurch and allocated the military serial number 126.[1] S.81 was delivered to Calshot on 25 May 1914 and accepted by the Navy on 2 June 1914.[1] It had three-bay wings with overhanging upper wings, and was powered by a 160 hp (119 kW) Gnome rotary engine.[2] It was first fitted with a 1½ pounder (37 mm) semi-automatic Vickers quick-firing gun in July 1914. Tests with this gun showed that recoil was severe, with claims that firing the gun would induce a stall.[3][4] It was fitted with a number of different guns for trials,[1] testing a six-pounder (57 mm) Davis gun (an early recoilless gun) in 1915.[5] In 1915 it had a dynamo and searchlight fitted. No longer needed for trials, it was deleted from the inventory in October 1915.[1]
