The S-4 was a single-seat advanced trainer of which about 600 were built, most going to the USAAS but a few also to the US Navy from 1917. The S-4B initial production version and a number of S-4C were powered by 74.5kW Gnome rotary engines, but the vast majority of aircraft produced were 59.6kW Le Rhone-powered S-4C. The designation S-5 was applied to a handful of S-4B fitted with float landing gears and operated by the US Navy.
