Arado Ar 240
 The Arado Ar 240 was a German twin-engine multi-role heavy fighter aircraft developed for the Luftwaffe during World War II by Arado Flugzeugwerke. Its first flight was in 1940 but problems with the design hampered development and it remained only marginally stable throughout the prototype phase. The project was eventually cancelled with the existing airframes used for a variety of test purposes.
