Also known as
  • OR-167
  • OP-167
  • UOR-167

The 37mm OR-167 is a Soviet 37x252mmSR fragmentation-tracer projectile in the UOR-167 fixed cartridge for the M1939 / 61-K 37 mm anti-aircraft gun family. Ordnance guides and specialist ammunition references distinguish the OR-167 projectile from the assembled UOR-167 round, while CAT-UXO records the alternate OR-167 (OP-167) label used in UXO references.

Designation Context

OR-167 names the projectile, UOR-167 names the assembled cartridge, and CAT-UXO's OP-167 label appears as an alternate rendering in UXO reference material.

Ammunition Family Notes

Reference sources separate the projectile, cartridge, and gun-family labels. OR-167 is the fragmentation-tracer projectile; UOR-167 is the fixed cartridge; and the 61-K / M1939 gun family is the firing weapon context.
