/ Dornier Do-11
The Dornier Do 11 was a German heavy bomber, developed in secret in the early 1930s.
It was originally called the Dornier F before being renamed by the Reichsluftfahrtministerium (RLM) in 1933, and was considered a heavy bomber at the time.
It came into service in 1932, a continuation of a line of bomber designs from the Dornier Do P in 1930, and the Dornier Do Y in 1931.
Prototype of the Do 11 before redesignation by the RLM.
