Captain Le Pere of the French Aviation mission to the USA, and Dwight Huntington designed a two-seat fighter, the LUSAC-11 (Le Pere United States Army Combat), which was built by the Packard Motor Car Company in 1918.
First flying in August 1918 piloted by Lt de Marmier, the LUSAC 11 (LUSAC = LePere US Army Combat) featured a plywood fuselage and box-type wing struts. It was the first US aircraft with a turbo-supercharger, and first to leave a vapor trail, on 27 February 1920.
Two prototypes and 24 production LUSAC-11s with Liberty engines [AS40013/40023, AS42129/42142, AS42151] and three LUSAC-21s with Bugatti engines were built, but contracts for nearly 3,500 were cancelled at end of First World War.
AS40021 was modified as a single seat LUSAGH-11 with longer wings and a canopied cockpit at McCook Field. LUSAGH = LePere US Army Ground Harassment.
