Ukraine Strikes Russian Submarine in Historic Black Sea Drone Attack

Ukraine’s State Security Service, known as the SBU, has announced a significant operation targeting a Russian submarine in the Black Sea. This historic attack took place at the naval port of Novorossiysk, resulting in critical damage to the vessel. The SBU utilized advanced underwater drones, referred to as “Sub Sea Baby,” marking this operation as the first of its kind.
Details of the Attack
Video footage released by the SBU captured a large explosion at the port, confirming the severity of the incident. The SBU reported that the submarine, a Kilo-class model, sustained extensive damage and is currently incapacitated.
About the Kilo-Class Submarine
- Capable of launching up to four Kalibr cruise missiles simultaneously.
- Known for stealth, with a hull designed to minimize sonar detection, earning it the nickname “Black Hole.”
- Estimated cost of construction is around $400 million, potentially rising to $500 million due to international sanctions affecting technological access.
Context of the Operation
The attack highlights Ukraine’s tactical advancements in maritime operations, particularly as Russian naval vessels have been displaced from Sevastopol Bay due to previous Ukrainian sea drone missions. Russian officials have not yet commented on this recent incident.
Diplomatic Discussions and Security Guarantees
This strike coincided with ongoing diplomatic efforts aimed at addressing the conflict in Ukraine. Ukrainian President Volodymyr Zelensky made statements in Berlin following two days of discussions with U.S. and Ukrainian leaders.
- Zelensky emphasized the need for clarity regarding security guarantees from allies before making frontline decisions.
- He expressed concerns about the monitoring of any ceasefire and the implications of disrupted monitoring missions.
German Chancellor Friedrich Merz stated that the U.S. had offered “significant” guarantees during the talks, although specific details were not disclosed.
