Also known as
- 53-BR-365
- 53-БР-365
- 85 mm BR-365

- 53-UBR-365
BR-365 is the blunt-nosed Soviet 85 mm armor-piercing ballistic-capped projectile used in the UBR-365 fixed round family for 85 mm tank, self-propelled, and field guns. Tank Archives' D-44 ballistic tables list the APBC projectile at about 800 m/s, while METIS describes 53-BR-365 as an APHE-T projectile with a steel ballistic cap and WW2 Equipment Data ties the UBR-365 complete round to the same weapons as UBR-365K.

Designation And Fuze Notes
The sources use both projectile and complete-round naming. The page keeps BR-365 as the projectile name while noting UBR-365 as the fixed round assembled around that projectile.
| Topic | Reader note | Source basis |
|---|---|---|
| Projectile designation | 53-BR-365 / BR-365 names the 85 mm armor-piercing projectile. | METIS and Tank Archives |
| Complete round | UBR-365 is described as the fixed round using the flat-nosed BR-365 projectile. | WW2 Equipment Data |
| Shape and role | Tank Archives calls BR-365 a blunt-tip APBC round; METIS describes an APHE-T projectile with a steel ballistic cap. | Tank Archives and METIS |
| Fuze caveat | Public sources differ on fuze wording: METIS describes an MD-7 base fuze/tracer assembly, while WW2 Equipment Data lists an MD-8 fuze for UBR-365. | METIS and WW2 Equipment Data |
Variants
BR-365 sits in a Soviet 85 mm armor-piercing designation set where blunt-nosed, sharp-tipped, APCR, and later APCBC projectiles appear in related ballistic tables.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Sharp-tipped AP-T complete-round family member | WW2 Equipment Data describes UBR-365 as a flat-nosed variant of the illustrated UBR-365K round, while Tank Archives lists BR-365K separately in the D-44 table at the same 800 m/s muzzle velocity. Sources: WW2 Equipment Data Soviet Explosive Ordnance - 85mm and 100mm Projectiles, Tank Archives: D-44 Ballistic Tables |
 | 85 mm HVAP / APCR projectile | Tank Archives lists BR-365P as a faster APCR round at 1050 m/s, separating it from the 800 m/s BR-365 APBC projectile. Sources: Tank Archives: D-44 Ballistic Tables |
 | Later 85 mm APCBC projectile | Tank Archives describes BR-367 as ballistically close to BR-365 but slightly faster and more precise in the D-44 tables. Sources: Tank Archives: D-44 Ballistic Tables |
 | Later 85 mm APCR projectile | Tank Archives lists BR-367P and BR-367PZh as 1020 m/s APCR projectiles in the same D-44 ballistic-table group. Sources: Tank Archives: D-44 Ballistic Tables |
Firing Weapons
Tank Archives places BR-365 in the ammunition set used by Soviet 85 mm guns and shows it in the D-44 ballistic tables. WW2 Equipment Data connects the UBR-365 complete round to the same 85 mm weapons listed for UBR-365K.
| Firing weapon | Weapon type | Firing evidence |
|---|---|---|
 | 85 mm divisional gun | Tank Archives' D-44 ballistic tables list BR-365 in the gun's 85 mm ammunition set, and Tankograd identifies the D-44 as part of the Soviet 85 mm family using shared ballistics. Sources: Tank Archives: D-44 Ballistic Tables, Tankograd: Soviet Towed Anti-Tank Guns |
 | ZiS-S-53 85 mm tank-gun platform | Tank Archives' 1943 GAU note identifies BR-365 as ammunition for 85 mm tank and self-propelled guns, and WW2 Equipment Data lists the ZiS-S53 tank gun among weapons firing the closely related UBR-365K while stating UBR-365 is fired from the same weapons.

85 mm Gun Compatibility
No direct public conflict-use source was found for this exact projectile, so the record remains relationship-only. The useful sourced context is compatibility across Soviet 85 mm guns that shared ammunition or ballistics.
| Weapon family | Catalog link | Source-backed note |
|---|---|---|
| D-44 divisional gun | | Tank Archives lists BR-365 in D-44 ballistic tables, including 800 m/s muzzle velocity and flat-shot ranges. |
| ZiS-S-53 tank gun | | Tank Archives ties BR-365 to 85 mm tank guns; WW2 Equipment Data names the ZiS-S53 among weapons firing the closely related 85 mm UBR-365K and says UBR-365 uses the same weapons. |
| D-5T / D-5S tank and self-propelled guns | Unlinked | Tank Archives' GAU note places BR-365 in 85 mm tank and SPG gun ammunition, and WW2 Equipment Data names D-5T85 and D5-S85 weapons in the same firing family. |
| 52-K / KS-12 anti-aircraft lineage | Unlinked | Tank Archives' GAU note states that the 85 mm tank and SPG guns used ammunition from the 85 mm anti-aircraft gun, while WW2 Equipment Data lists the M1939 anti-aircraft gun for the related round family. |

Timeline
BR-365 Key Events
GAU ammunition instruction
Tank Archives' translated GAU note says 85 mm tank and self-propelled guns were to use BR-365 armor-piercing tracer rounds against armored targets.
D-44 development ordered
Tankograd describes the towed 85 mm divisional gun project as ordered in 1944 to use the same 85 mm ballistic family as Soviet tank and self-propelled guns.
Postwar D-44 service context
WeaponSystems.net lists the D-44 as entering service in 1946, giving BR-365 a postwar field-gun relationship in addition to wartime tank and SPG ammunition use.
