 M-4s were actually put into service.

To remedy this problem, the Myasishchev design bureau introduced the 3M, known to the West as the 'Bison-B', which was considerably more powerful than the previous version. This new model first flew in 1955

Neither the M-4 nor the 3M ever saw combat, and none were ever converted for low altitude attack, as many American B-52s were, nor were any ever exported to the Soviet Union's allies.

Production of the Bison aircraft stopped in 1963, by which time 93 of them had been built. The last aircraft, an M-4-2 fuel tanker, was withdrawn from service in 1994.

 heavy lift aircraft converted from 3MN-2 tankers, with very large loads carried piggy-back above the fuselage. The single vertical fin/rudder was replaced with two large rectangular fin/rudders at the tips of the horizontal stabilizers to improve control due to the turbulence caused by the cargo pod.

With the withdrawal of the Myasishchev bombers and tankers the vast majority of the retired airframes were broken up under the terms of the relevant arms limitation treaty. Four aircraft are known to survive:
