Naval five-inch guns have accumulated successful drone engagements. The geometry is easiest when the weapon approaches the defending warship or its formation, because fire-control systems are optimized for inbound threats. A drone crossing the escort's bearing toward a merchant vessel is harder to engage with gunfire and may require a missile. The distinction shows why reports of weapon performance need the engagement geometry, not just a count of targets.

Why naval guns work better against drones attacking the warship
Five-inch guns have performed well against inbound drones, but crossing targets aimed at merchant ships create a harder fire-control problem.
