Ukrainian OWA-EFP Warhead

7 Aug 2025

Ukrainian explosively formed projectile (EFP) warhead for a one way attack (OWA) uncrewed aerial vehicle (UAV).

Current designation unknown
Designed to counter cope cages by negating stand-off effect
Reported to penetrate 50 mm armour at 1 m stand-off, followed by a 16 mm plate (approx. 100 mm behind), and deform a third 16 mm plate
Warhead casing appears to be aluminium so limited fragmentation effect unless additional pre-formed fragmentation sleeve used
Currently still in warhead testing phase without introduction to UAV, but mention of Backfire UAV in the news article
