Ukraine made the naval drones sinking Russian warships 'deadlier' by arming them with bigger warheads, general says

• Ukraine has used naval drones to wreak havoc on Russia's Black Sea Fleet. 
• These systems were introduced in 2022 and have been used in a number of attacks on Russian vessels.
• A Ukrainian general said the drones have been upgraded over time and outfitted with larger warheads.

Exploding drone boats, one of Ukraine's more innovative weapons as it battles Russia's Black Sea Fleet without a proper navy, have become even bigger threats over time.

Ukrainian naval drones have been used to damage and sink Russian warships, as well as target infrastructure, since their introduction in 2022. The hits have been increasingly devastating.

A general in the Security Service of Ukraine, or SBU, said these systems have received major upgrades over the course of the war and are now "stronger, more efficient, and deadlier" than they were before.
