85 mm O-367A high-explosive round
Also known as
- 53-O-367A
- 53-О-367А
- O-367A
- 85 mm O-367A

- UO-367A
The 85 mm O-367A, also cataloged as 53-O-367A and used in the 53-UO-367A fixed round, is a Soviet cast-iron high-explosive fragmentation projectile for the postwar 85 mm gun family. METIS ties the complete round to D-44, ZiS-S-53/T-34-85, D-5, and 52-K/KS-12 weapons, while D-44 ballistic tables document reduced-charge O-367A employment with KTM-family point fuzes, a 9.54 kg projectile, and a 15.65 km maximum range from the D-44.

Designation And Construction Notes
The record separates projectile and complete-round naming because sources use both layers of the Soviet ammunition designation. METIS identifies 53-O-367A as the projectile and 53-UO-367A as the fixed unitary round, while Tankograd frames the 1956 load as a reduced-charge cast-iron fragmentation shell in the postwar 85 mm family.
| Topic | Reader note | Source basis |
|---|---|---|
| Projectile designation | 53-O-367A / O-367A names the high-explosive fragmentation projectile. | METIS |
| Complete round | 53-UO-367A / UO-367A names the fixed cartridge assembled around the projectile. | METIS and Tankograd |
| Casing material | Tankograd describes the O-367A family as a cast-iron fragmentation load, explaining why the reduced-charge velocity is the important service context. | Tankograd |
| Explosive fill | Tankograd lists a 670 g explosive filler, which is now separated from the projectile and complete-round weights in the specifications. | Tankograd |
Firing Weapons
The 53-O-367A projectile appears in D-44 ballistic tables, while METIS identifies the 53-UO-367A complete round as compatible with several Soviet 85 mm gun families.
| Firing weapon | Weapon type | Firing evidence |
|---|---|---|
 | 85 mm divisional field gun | Tank Archives' D-44 ballistic tables include O-367A high-explosive data for the gun, and WeaponSystems.net describes the D-44 as a fixed-case 85x629mmR ammunition user. Sources: Tank Archives: D-44 Ballistic Tables, WeaponSystems.net: 85mm D-44 |
 | 85 mm ZiS-S-53 tank-gun platform | METIS states that the 53-UO-367A fixed round could be fired from the ZiS-S-53 tank gun used in the T-34-85, and Tankograd notes D-44, tank, and self-propelled-gun cartridge-case marking.

85 mm Gun Compatibility
The O-367A page is relationship-only because no direct combat-use source was found for this exact round. The useful sourced context is compatibility: METIS treats the 53-UO-367A as a fixed round for multiple Soviet 85 mm weapons, and Tank Archives gives the D-44 ballistic-table data.
| Weapon family | Catalog link | Source-backed note |
|---|---|---|
| D-44 divisional gun | | Tank Archives lists O-367A in the D-44 high-explosive ballistic tables, and WeaponSystems.net identifies the D-44 as an 85x629mmR fixed-case ammunition user. |
| ZiS-S-53 tank gun | | METIS names the ZiS-S-53 tank gun in the T-34-85 as one of the weapons able to fire the 53-UO-367A complete round. |
| 52-K / KS-12 anti-aircraft guns | Unlinked | METIS lists these 85 mm anti-aircraft guns among compatible weapons for the 53-UO-367A round; the catalog currently has no standalone 52-K or KS-12 record. |
| D-5S / D-5T 85 mm guns | Unlinked | METIS also names D-5S and D-5T weapons, tying the round to the broader Soviet 85 mm tank and assault-gun ammunition family. |
