The Dornier Do 23 led a short service life with the German Luftwaffe before being replaced by the capable Heinkel He 111.
Detailing the development and operational history of the Dornier Do 23 Medium Bomber. Entry last updated on 5/14/2018. Authored by Staff Writer. Content ©www.MilitaryFactory.com
The aircraft carried a straight high-wing monoplane planform with a conventional tail unit (single vertical fin, low-set planes), a fixed tail-dragger undercarriage (with spatted main wheels), and leading edge engine nacelles (one per wing). The fuselage featured slab sides and housed the cockpit at front, crew positions along its length and the internal bomb bay. 3 x 7.92mm MG 15 machine guns were fitted as defensive armament - one at the nose, another at a dorsal gun position and the final gun at a ventral position. The aircraft was cleared to carry up to 2,200 pounds of conventional drop stores. The typical crew arrangement numbered four.
The powerplant of choice became 2 x BMW VIU V12 liquid-cooled engines of 750 horsepower each. Performance specifications included a maximum speed of 160 miles per hour, a range out to 930 miles and a service ceiling of 13,780 feet. Empty weight was 12,345 pounds against a Maximum Take-Off Weight (MTOW) of 20,282 pounds. Dimensions were a length of 18.8 meters, a wingspan of 25.6 meters and a height of 5.4 meters.
A prototype Do 23 saw its first flight during 1934 and brought along some improvements in handling though performance was clearly lacking for a bomber platform. Nevertheless, the type was ordered into serial production and managed a healthy pre-war total of 282 aircraft before the end of its run. Initial production models were designated as "Do 23F" and an improved version with better engines (featuring glycol cooling) appeared as the "Do 23G".
Despite their rather obsolete status at the start of World War 2 in September of 1939, the aircraft was still in circulation in some number and fell to the Luftwaffe arm of Czechoslovakia during the early phases. Some of the German fleet was also passed on to the Hungarian Air Force. By and large, the bomber was wholly outclassed by the time the war went into full swing and it was superseded in the Germany inventory by more appropriate players such as the Heinkel He 111, the Junkers Ju 88 and Dornier's own Do 17 - all detailed elsewhere on this site.
