R-3 BSh by A.N.Tupolev

R-3 was suggested as a platform for armored strike aircraft (Bronirovannyj Shturmovik). Engine, pilot and gunner had to be protected by steel armor plates. Calculations performed by A.I.Putilov demonstrated that extra weight added by armor has to be at least 400kg.

It was too much for R-3 airframe and available engines. Plans to convert series R-3 vere abandoned.
