the SBU, said Monday that it struck a Russian submarine in the Black Sea port of Novorossiysk, causing critical damage to the vessel and effectively disabling it.
In a statement, the SBU said the operation, which used underwater “Sub Sea Baby” drones, was the first attack of its kind. Video shared by the SBU showed a large explosion at a port.
“As a result of the explosion, the submarine suffered critical damage and was effectively put out of action,” the SBU said. CNN could not independently verify the claim.The Kilo-class submarine is used to launch Kalibr cruise missiles, firing up to four at a time, according to the SBU statement. Russia has used the missiles throughout the war to strike Ukraine.
The agency added that the submarine is known as a “Black Hole” because of the hull’s ability to absorb sound and remain undetectable by sonar. It said that class of submarine costs around $400 million. Due to international sanctions, which have hampered Russia’s access to technological components, building a similar submarine could now cost up to $500 million, the SBU said.
Russian officials did not immediately comment on the incident.
