OF-471 is a Soviet 122 mm high-explosive fragmentation projectile for A-19 and D-25-family guns. U.S. Ordnance Intelligence firing tables identify OF-471 and OF-471H in the A-19S, D-25S, and D-25 table set, while ammunition references describe VOF-471 as the complete separate-loading round using the OF-471 projectile with RGM or D-1 fuze options.

Firing Guns

A-19 ammunition tables, the U.S. foreign firing table, and specialist ammunition references place OF-471 in the 122 mm A-19 and D-25-family gun line.

The A-19 ammunition table lists OF-471 as a 122 mm HE-fragmentation shell, and WW2 Equipment Data identifies the same projectile as part of the VOF-471 complete round used by A-19 and related D-25-family guns.

The 1951 U.S. Ordnance Intelligence firing table names OF-471 and OF-471H in the A-19S, D-25S, and D-25 table set; WW2 Equipment Data and the Commons shell plate also place OF-471 in the D-25-family ammunition set.

OF-471 remains relationship-only because the researched sources support gun compatibility and ammunition identity, not direct use by the shell in a named catalog conflict.

Round Notes

The sources distinguish the projectile designation from the complete separate-loading round. OF-471 is the high-explosive fragmentation projectile; VOF-471 is the complete round context used with A-19 and D-25-family guns.

Projectile

OF-471 / 53-OF-471, a 122 mm high-explosive fragmentation projectile with a roughly 25 kg projectile mass in the tabulated sources.

Complete round

VOF-471 / 53-VOF-471, described by WW2 Equipment Data as the complete round using the OF-471 projectile.

Fuzes

RGM or D-1 fuze options are listed for OF-471 in the D-25 ammunition table and WW2 Equipment Data round note.

OF-471 Key Events

  1. Included in A-19S/D-25 firing tables

    The Soviet firing-table set translated by U.S. Ordnance Intelligence covers OF-471 and OF-471H high-explosive fragmentation shells for A-19S, D-25S, and D-25 guns.

  2. U.S. foreign firing table issued

    U.S. Ordnance Intelligence prepared FT-F-122-2 in March 1951 for Soviet 122 mm A-19S, D-25S, and D-25 guns firing BR-471, OF-471, and OF-471H projectiles.

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.

Public references do not describe the designation consistently: Fenix Insight identifies it as a nose-fuzed, boat-tailed, spin-stabilised HE-frag projectile, while U.S. WEG/FAS tables place a 3OF-56 complete projectile weight in a rocket-assisted ammunition row for the D-30A and 2S1.
