In 1936 MBR-2 was modified to accommodate 800hp M-34B engine with 2-blade propeller. New aerodynamically improved metal tail was installed, as well as new rear gunner's enclosed turret (SUMBR-2). Pilot's cockpit also became enclosed.
First prototype, designated TsKB MS-1 differed from (most) series aircraft by its amphibious landing gear and non-standard rear turret. Series MBR-2bis was built in both flying boat and amphibian variants. In winter it could be installed on skis to operate from the ice and snow.
Some series MBR-2bis had M-34NB engine with air compressor (Nagnetatel). Those aircraft had improved ceiling (plus 300m), but were heavier by 155kg and slower by 23km/h. MBR-2bis (M-34NB) also differed by improved radio equipment and carried two photo cameras instead of one.
In 1941 one MBR-2bis (amphibious variant) was equipped as a Headquarter aircraft. it had four windows on each side and two cabins equipped similar to the passenger variant. One was occupied by High Brass, another - by deputies and/or security guards. This aircraft served with Baltic Fleet Command through all War without an accident.
Approximately 900 built.
