The Dornier Do 11 was the first regular bomber of the Air Force of the Third Reich .
development
The aircraft was designed on the basis of the Dornier Do F , a twin-engine passenger aircraft developed by Claude Dornier in Japan in 1925 . The aircraft was redesigned in 1932 for use as a transport aircraft and equipped with two Siemens Jupiter radial engines with 510 hp each. In this configuration, the version still called Do F was incorporated into the new German Air Force as a makeshift bomber in 1933. From 1934 the Do F , which had been developed into a regular bomber, was accepted into the Air Force as the Do 11 . The structure of Do 11 corresponded to Do F, only the chassis was designed as a rigid chassis. The aircraft was a stripped shoulder-wing aircraft in all-metal shell construction with rigid normal landing gear. The crew consisted of four men: a pilot, the radio operator and two gunners, each housed in open stands.
Twelve Do 11 were delivered to the Royal Bulgarian Air Force in mid-1937 .
