The ANT-8 was a prototype flying boat developed under the direction of Andrei Tupolev. The military assigned it the designation "MDR-2," an acronym for Morskoi Dalnii Razvedchik which translates to Naval Long-Range Reconnaissance.
Design and development
Although the request for construction of the ANT-8 was made to Tupolev and TsAGI in 1925, progress was initially limited due to prioritization of other designs. It was not until 1930, with Ivan Pogosski at the helm, that substantial work commenced on this aircraft. The maiden flight took place on January 30, 1931, with S. Riballschuk as the pilot. Shortly after this event, the Tupolev ANT-14 also completed its first flight.
Construction
The ANT-8 featured an all-metal build, incorporating a hull crafted from Duralumin and wings reminiscent of those on the Tupolev R-6. Special attention was devoted to the fuselage design, where engineers integrated the floats into the load-bearing framework. Propulsion was provided by two BMW VI engines arranged in a pusher configuration above the wings. The cockpit was enclosed and accommodated two pilots, while defensive armament consisted of turrets located at the nose and behind the wings, each equipped with twin Degtyaryov light machine gun#DA-2 (DA-2) machine guns. The aircraft could carry up to 500 kg (1,102 lb) of bombs suspended beneath the wing roots.
Despite demonstrating outstanding seaworthiness and offering valuable insights into flying boat hull design for Tupolev, the Soviet Navy considered further development of the ANT-8 unnecessary. It was judged obsolete and expected to be replaced by the Chetverikov MDR-3. Consequently, only a single unit was produced, although its hull underwent multiple modifications over time.
