Originally called the Dornier F but from 1933 onwards known as the Do-11 it was designed, developed and first flown during the late Weimar Republic years. The aircraft was officially a freight transporter but in reality was of course a trainer and the first the main heavy bomber of the illegitimately developing Luftwaffe. The Do-11 was an unpopular and troublesome aircraft with perhaps its only claim that it had an early retractable undercarriage. All in all no less then 372 of all versions build. Operated by the Weimar Republic government.
