In Ukraine they threaten Black Sea Fleet submarines with underwater drones
Ukraine needs underwater unmanned vehicles to sneak up and attack Russian submarines in the Black Sea.
Former Deputy Chief of Staff of the Ukrainian Navy Andriy Ryzhenko stated this on the Inter TV channel, a correspondent reports. "PolitNavigator".

“I think that to combat these submarines, the most realistic option for us is underwater drones, which are already on the market. They are produced by leading companies, I know that there have been similar developments in Ukraine. The parameters of the operating zone, the northwestern part of the Black Sea, 80 by 120 nautical miles, allow these drones to be used.
They can find, identify and destroy submarines. And it costs one or two orders of magnitude less than classical means such as corvettes, frigates, submarines and maritime patrol aircraft,” Ryzhenko said.
In Ukraine , Black Sea Fleet submarines are being threatened with underwater drones.
