Ukraine Crippled Russia’s Black Sea Defenses in One Coordinated Strike

Описание: Russia believed Novorossiysk was untouchable. After losing Sevastopol as a viable base, the remaining assets of the Black Sea Fleet were compressed into what Moscow considered a fortified safe harbor. In December 2025, Ukraine proved that assumption wrong.

This video breaks down how Ukraine crippled Russia’s Black Sea defenses in one coordinated sequence. First, the removal of a critical anti-submarine detection asset. Then, the first confirmed combat use of an underwater naval drone against a submarine inside a defended harbor. Not in open waters. Inside Novorossiysk.

We analyze how the strike on Russia’s IL-38N maritime patrol aircraft at Yeysk air base removed the airborne anti-submarine “lid” protecting the port. Then we walk through the Sub Sea Baby underwater drone operation that targeted the B-271 Kolpino, a Project 636.3 Kilo-class submarine valued at hundreds of millions of dollars.

This is not just about one submarine. It’s about how Ukraine identified a single point of failure in Russia’s layered naval defense architecture and exploited it with precision. The sequencing matters. The doctrine matters. And the long-term implications for modern naval warfare matter even more.

Inside this analysis:
– The decline of Russia’s Black Sea Fleet since 2022
– The sinking of the Moskva and the shift from Sevastopol to Novorossiysk
– The rise of Ukrainian naval drones like Magura V5 and V7
– The strategic impact of submarine-launched Kalibr cruise missile reductions
– The economics of asymmetric naval warfare
– Why this changes global port defense calculations

We also examine reporting and assessments from the British Ministry of Defence, open-source satellite analysis, and international defense observers to understand what this strike forced Russia to confront: a fortress that is no longer secure.

If you’re following the Russia-Ukraine war, Black Sea naval warfare, submarine operations, unmanned naval drones, or modern military strategy, this breakdown connects the tactical event to the larger strategic shift happening in real time.
