ROME, July 9 — The shift is underway in the Black Sea, and it’s one that could rewrite the naval balance of power in the region. NATO’s Response Force, activated in February 2022, has now increased naval patrols in these contested waters, and the strategic calculus for Russia’s Black Sea Fleet is changing fast. The numbers, when they come from analysts, are stark.
Experts at the Royal United Services Institute (RUSI) report that Russia has lost a significant portion of its fleet — 20% — since 2022. That’s a tangible hit to Moscow’s naval capability, and it’s forcing a tactical rethink.
Following strikes in May 2024, the Kremlin may be compelled to pull its remaining warships further east, to ports like Novorossiysk and Tuapse. That’s a retreat from the forward positions that once threatened Ukraine’s coast.
The Bosporus Bottleneck
Turkey, a NATO member, holds the keys to this chessboard. Under the 1936 Montreux Convention, Ankara controls the Bosporus Strait, and since March 2022, it has restricted the passage of warships through that vital chokepoint. That means Russia cannot easily reinforce its Black Sea Fleet from the Mediterranean.
The fleet that’s there is largely the fleet it has to work with, and it’s taking damage. This is where the trend underneath becomes clear.
Ukraine is pursuing a deliberate strategy to degrade the fleet further, specifically to prevent any amphibious assault on the port city of Odesa. That threat has hung over the conflict since the early days, and Kyiv is determined to make it impossible. For Ukraine, denying Russia sea control is not just a tactical goal — it’s existential for its southern coastline.
Retaliation and Risk
Russia, however, is not expected to take this lying down. The source material notes that Moscow may retaliate with increased missile strikes on Ukrainian infrastructure. That’s a grim pattern that has already played out repeatedly — strikes on the power grid, on ports, on grain silos.
The question is whether the loss of naval capability will push the Kremlin toward even more aggressive long-range bombardment. The NATO Response Force, activated at the start of the war, provides the framework for the increased Allied naval presence.
It’s a rapid-reaction tool, and its deployment in the Black Sea sends a clear signal. But the geography is tricky — the Montreux Convention limits how many NATO ships can transit the Bosporus, and for how long. Turkey, balancing its NATO obligations with its own regional interests, has walked a careful line.
What’s Changing
The long-term outcome, as analysts see it, could be a fundamental shift. Ukraine may permanently deny Russia the ability to control the Black Sea. That would alter the balance of power in the region for years to come.
It’s not just about this war — it’s about the posture of both fleets in a post-conflict landscape. Watch this space.
The Black Sea is a crowded theater, and the moves being made now — the patrols, the strikes, the retreats — are setting the stage for the next phase. The trend underneath is clear: Russia’s naval dominance in the region is eroding, and NATO is stepping into the gap. Where that leads, no one can say for certain, but the pieces are moving.
