Packard-Le Pere LUSAC-11 and LUSAC-21 (USA)
The LUSAC-11 was a single-seat fighter of 1918 powered by a 317 kW (425 hp) Liberty 12 engine. Only 30 had been built by the Armistice, when orders for nearly 3,500 were cancelled. The 313 kW (420 hp) Bugatti 16-powered LUSAC-21 appeared after the war but remained a prototype.
