G-1 by A.N.Tupolev

Retired TB-1 bombers with M-17 engines were stripped of armament and reassigned to civil service. Saved weight compensated for previous gain during repairs, and flying performance was practically identical to freshly built bombers.

Aeroflot used G-1 only as a cargo plane, it was banned from carrying passengers. It was an over-insurance, because no fatal accident happened with those rugged planes in civil service. Despite they were used to the very limit, staying in operation during years and years and accumulating thousands hours of flight time.

Both land-based and floatplane versions were employed by Aeroflot
