Capitaine G. Le Père, an aircraft designer on loan from the French, designed the LUSAC 11 for the US Army, centered on the 400hp Liberty engine. "LUSAC" stood for "Le Père U.S. Army Combat". The plane was robust, fast, maneuverable, and well-armed, and it would have been a potent weapon had the war continued. Thirty of them were undergoing evaluation when the war ended, and though there were changes need to the fuel feed and cooling, pilots thought the plane was quite promising.[1]
