|FIGHTING SCOUT||Virtual Aircraft Museum / USA / Curtiss|
During 1917, the US Navy issued the Curtiss company with a contract for five single-seat fighting scout float seaplanes powered by a US-built version of the 100hp Gnome nine-cylinder rotary, the GS designation indicating "Gnome Scout". These were completed under the designation GS-2 when a supplementary contract was issued for a sixth aeroplane which was assigned the designation GS-1. The GS-1 was a single-seat triplane with a single central float and outrigger stabilizing floats which drew heavily on Curtiss S-3 experience. An unusual feature was the introduction of shock absorbers in the struts between the fuselage and the central float. These resulted in the float angle being subject to change at high speed on the water and producing an undesirable porpoising. Delivered to the US Navy early in 1918, the GS-1 was flown several times by US Navy acceptance pilots, but was eventually damaged beyond repair as a result of a heavy landing. The five similarly-powered GS-2s differed from the GS-1 primarily in being of biplane configuration, but little is recorded of these aircraft apart from the fact that they suffered from tail heaviness.
