 Ukraine's naval drones are becoming a big problem for the Russians in the seas. Ukraine has launched a serial production of unmanned surface vessels or drone boats. The country's deputy prime minister in charge of innovations, education, science and technology said, We are now actively scaling up the production of unmanned surface vessels. We have already launched a serial production of them, said Mikhail Fyodorov, who doubles as the country's minister of digital transformation. The minister gave no details about the production's potential output or the number of drone boats that have already been manufactured. He also said that Ukraine has been designing new models of uncrewed surface vessels. The Russian Defense Ministry has been regularly reporting about destroying Ukrainian drone boats in the Black Sea and striking facilities where they are stored or produced. Russian sea drone features include built-in explosives and cameras which beam back images to the person controlling it. Long-range targets are typically pre-programmed into the drones when launched. Ukraine has carried out at least 15 attacks with sea drones targeting military ships, Russia's naval base in Sevastopol and Novorossiysk harbour. This is based on announcements by Russian and Ukrainian authorities and local media reports. Ukraine's deployment of sea drones at relatively low cost marks a new era for naval warfare. The tactic poses an increasing risk to Russia according to some analysts. Compared with naval vessels, sea drones are harder to detect on radar because they travel low on the water and they make far less noise.
