Mobius report 31/2026 – OFBCh HE-FRAG Warheads and A-795, B-795, B-919 Fuzes in Russian Loitering Munitions

Toward the end of 2025, documentation began to emerge showing the use of OFBCh-series explosive warheads intended for integration with UAVs. Although warheads from this series have been known and observed in various configurations since 2024, the recently documented variants – OFBCh-0.4 and OFBCh-0.5 – appear to be newly introduced and are designed for engaging hostile UAVs. Until this point, only the OFBCh-0.8 variant had been observed in this role.

Alongside the appearance of these warheads, three fuze types have been identified: A-795, B-795, and a newer model, B-919. These fuzes are designed to be initiated during flight.
