BR-471B

Also known as
  • 53-BR-471B

BR-471B is a Soviet 122 mm APBC shell developed in 1944 as an improved successor to BR-471. Tankograd describes it as a blunt-tipped round with a 25 kg projectile, A-IX-2 bursting charge, and 795-800 m/s muzzle velocity, while the A-19/D-25T Commons plate and later Soviet heavy-tank reporting place it in the postwar 122 mm heavy-gun loadout.

Design Notes

The surviving references describe BR-471B as a short-lived wartime improvement that stayed useful after the war because Soviet heavy tanks and guns kept the 122 mm system in service.

DevelopmentTankograd says BR-471B was tested in summer 1944 and began supplanting BR-471 in 1945.
Ballistic contextTank Archives' comparative-penetration article gives the 122 mm D-25 gun's trial results against Panther armor, useful context for BR-471B's improved anti-armor role.
Heavy-tank contextTankograd says the round was originally available to the T-10 in 1953, and Tank Archives notes that the Soviets kept the 122 mm gun on heavy tanks until the T-10 era.

D-25T armed the wartime IS-2 heavy tank and later IS-series vehicles, with directly sourced use on Soviet IS-2s in the Second World War, Egyptian IS-3M tanks in the 1967 Six-Day War, and captured Israeli IS-3 fixed bunkers in the 1969 War of Attrition. D-25S was the semi-automatic self-propelled-gun variant associated with ISU-122S, and the family used separate-loading A-19/D-25 ammunition including OF-471 high-explosive fragmentation and BR-471 armor-piercing projectiles.
