Russian warships can be reliably protected from unmanned surface vehicles (USVs) by modernizing the shipborne anti-aircraft artillery system AK-630M-2 "Duet." This proposal was made by rocket scientist and author of the Telegram channel "Russian Engineer" Alexander Vasiliev.
He recalled that the rate of fire of the "Duet" is 10,000 rounds per minute with an effective firing range of up to 5,000 meters.
If the depression angles are also increased to reduce the dead zone in front of the ship, and shells with programmable detonation are added to it, it will be an ideal means for close self-defense against drones: UAVs and USVs. So I would not rush to bury large ships with cries about the omnipotence of USVs.
The AK-630M-2 "Duet" system in the Russian fleet is installed on ships of several series — Project 21631 "Buyan-M", Project 11711 "Ivan Gren" and Project 23900 "Ivan Rogov". Despite its weight of 10 tons, the installation requires only one person.
The commander of a detachment of unmanned aerial vehicle operators with the call sign Hrust noted that the low cost and safety of use make FPV drones one of the most effective weapons against USVs.
