The Beresin UB ( Russian Универсальный Березина , Beresin Universal) was a heavy machine gun that was used in Soviet aircraft during World War II .
Emergence
In 1937, the designer Mikhail Yevgenyevich Beresin began developing an aircraft on-board weapon for the Russian infantry cartridge with a caliber of 12.7 × 108 mm (comparable to the American .50 Browning Machine Gun ). The machine gun was given the designation Beresin Synchronni (BS) and was officially adopted into the equipment of the armed forces two years later. On the basis of the BS, the improved UB model was created in three variants:
- UBK (for assembly in the wings)
- UBS (synchronized for shooting through the propeller circle)
- UBT (manually operated turret machine gun in shooting ranges)
technology
The Beresin UB is a gas pressure gun, which reached a rate of fire of up to 800 rounds per minute for a heavy machine gun. The ammunition was fed via a decay belt. The UBK and UBS variants were loaded pneumatically, the UBT was operated by hand.
commitment
The MG Beresin UB was widely used as an on-board weapon in the air forces of the Soviet Union and was used in the following Soviet combat aircraft (incomplete list):
