The Avia S-199 is a propeller-driven Messerschmitt Bf 109G-based fighter aircraft built after World War II using the Bf 109G airframe and a Junkers Jumo 211F engine in place of the original and unavailable Daimler-Benz DB 605 engine. It is notable as the first fighter obtained by the Israeli Air Force, and used during the 1948 Arab-Israeli War. Constructed in Czechoslovakia, with parts and plans left over from Luftwaffe aircraft production, the aircraft had numerous problems and was generally unpopular with its pilots. Czechoslovak pilots nicknamed it Mezek ("Mule"). The Kbely museum, outside Prague, has both this single seater and a two-seat trainer.
