SB-2M-100, A.A.Arhangelsky/ A.N.Tupolev

When the ANT-40.2 prototype was introduced for mass production, its size was slightly increased. Production aircraft was powered by license-built Hispano-Suiza 12Y, designated M-100. Propellers (2-blade) had fixed pitch.

Series built aircraft had substantial weight increase due to lack of technological discipline, and A.A.Arhangelsky (now responsible for mass production) put a great efforts to bring aircraft to proper shape. Despite his struggle, factory built SB-2M-100 demonstrated substantially worser performance than prototype built in experimental workshop. Anyway, aircraft was a success.

Some shortcoming, like little room in the front cockpit, somewhat restricted view (and defence fire coverage) were payments for the high speed. It was hard to overcome them without radical redesign of the SB.

Since 1937 some aircraft were built with protected tanks. During winter SB was used on skis. In early models (including SB-2M-100) skis were not retractable.
