152 mm round for Giatsint howitzer

Also known as
  • TRM 152 mm round for Giatsint
  • 152 mm round for 2A36 Giatsint-B and 2A37 Giatsint-S
  • OF-45

Transmobile's 152 mm round for Giatsint howitzer is a Bulgarian-listed Frag-HE artillery round for the 2A36 Giatsint-B and 2A37 Giatsint-S guns. Its product data gives a 43.56 kg OF-45 projectile, 864 m/s muzzle velocity, 6,500 to 24,700 m range, and an RGM-2 PD fuze; separate 3OF29 references are kept as Giatsint-family context, not as proof that the Transmobile round carries that designation.

Design Notes

The Transmobile listing and the 3OF29 references describe closely related Giatsint-family ammunition, but they should not be merged into one designation without a direct source. Transmobile's product row names OF-45 in the projectile-weight field, while the Commons image and Fenix Insight page identify a separate 3OF29 reference projectile for the same gun family.

3OF29 context

Fenix Insight and Commons identify 3OF29 as a Soviet/Russian HE-frag projectile for Giatsint systems, useful for compatibility context but not as proof of the Transmobile product designation.

Manufacturer and military references describe separate-loading HE projectiles with full or reduced propelling charges, while U.S. security-assistance reporting documents 122 mm artillery rounds among ammunition committed to Ukraine and TWZ reporting describes a pair of 122 mm rounds as a standard AQ-400 Scythe payload.
