Sesquiplane twin-engine bomber of very clean wooden design. Lower wing carried engines and fixed landing gear. Wing struts - steel tubes with airdynamic fairings.

Project was initiated in 1927, and in Spring 1930 aircraft was flown. Its performance was better than one of the TB-1 (ANT-4) (already in mass production and in service), but not good enough for 1930. Moreover, biplane (sesquiplane) layout for heavy aircraft already was considered obsolete by Soviet authorities and experts.

No production followed.
