The SPAD S.G1 and SPAD S.G2 were French single seat tractor biplanes of ca 1915/16, following similar arrangements to the SPAD S.A2 family with the propeller and engine buried in the fuselage and a pod suspended in front of the engine.[1][2] A single SPAD S.A-1 was converted with a small circular section pulpit nacelle mounting a mock-up of a fixed forward-firing machine-gun and smaller wings.
