In 1942, the United States Army Air Force (USAAF) in Australia issued a requirement for a light armoured car to be used in patrolling and airfield defence. The requirement resulted in a vehicle designated Scout Car S1 (American). About 40 vehicles were produced by Ford Australia.
The vehicle was based on a Ford F15 4x2 chassis (a single 4x4 vehicle was built). The open-topped armoured hull was similar to that of the M3 Scout Car. The armament consisted of one .50 inch (12.7 mm) heavy machine gun and two .30 inch machine guns on skate rails, operated by the crew of five.
