Project of attack aircraft with vertically movable guns. Firing angle could be from 0° to -25°, allowing continuous firing on same target from horizontal flight. Twin-tailboom layout with pusher propeller provided excellent view for pilot and a lot of room for heavy guns in fuselage. The second crew member (gunner/radio operator) was seated back-to-back with the pilot and operated remotely-controlled defensive turrets on the tailbooms.
VD-251 engine (X-type) had a gearbox driving 2-rotor counter-rotating unit AV-28 (3.6m diameter). New type of armour steel was used.
Aircraft had two parallel control systems (right and left). It retained control in case of heavy damage of any of two.
Project started in 1948. Different sources contradict each other: some insist that '218' was built, while other claim that aircraft was not finished and project was cancelled when S.M.Alexeev design bureau was closed.
