Flug- und Fahrzeugwerke Altenrhein AG was a Swiss aircraft and railroad car manufacturing company based at Altenrhein. It was originally part of Dornier Flugzeugwerke, but was split off in 1948. Flug- und Fahrzeugwerke means "aircraft and vehicle works" in German. In the years following World War II, FFA manufactured fighter aircraft for the Swiss Air Force, based on Morane-Saulnier designs as the D-3803. These were eventually replaced in service by surplus P-51 Mustangs.
