How Drones, Mines, And Missiles Contained Russia’s Black Sea Fleet – Analysis

Eurasia Review | Kayvan Amyot-Ariya

Ukrainian Navy integrated naval mines, land-based Neptune anti-ship cruise missiles, and uncrewed surface vehicles (USVs) to establish effective littoral denial across the Black Sea. Early missile strikes sank the flagship cruiser Moskva and forced Russian warships to maintain a standoff distance exceeding 100 kilometers. This spatial buffer facilitated the liberation of Snake Island on July 30, 2022, ultimately reopening critical commercial sea lines of communication to Odessa.

Subsequent long-range USV strikes targeting harbor facilities in Sevastopol and Novorossiysk compelled Moscow to relocate its principal surface combatants and entire submarine fleet by October 2023. Stationary fleet berths became highly vulnerable. Compiled tracking data from August 2022 to April 2025 indicates that the Russian Navy nevertheless preserved its core operational capability to mass surface assets for concentrated Kalibr cruise missile salvos. Land-based sea denial imposes severe operational friction but cannot entirely substitute for active, organic surface command.

Comment

The relocation of Russia's Black Sea Fleet assets from Sevastopol to Novorossiysk challenges classical maritime doctrine regarding the sanctuary of port defensive perimeters. Julian Corbett's concept of the fleet-in-being assumed that an inferior naval force could safely shelter in harbour until conditions favoured operational sortie. Ukraine's integration of land-based Neptune missiles and persistent uncrewed surface vehicle raids systematically eroded this harbour sanctuary without requiring a matching surface combatant fleet.

This loss of harbour sanctuary forces Russian commanders at Novorossiysk to redeploy shore-based Tor-M2KM systems and floating boom barriers to shield docked combatants. At Novorossiysk, stationary platforms like Project 11356M frigates remain exposed to low-observable surface vectors that exploit static port geometry. The vulnerability of Project 11356M frigates inside Novorossiysk demonstrates that static harbour infrastructure no longer provides operational immunity against persistent uncrewed strike vectors.

Strategic Question for Discussion

If static port geometry at facilities like Novorossiysk permanently exposes surface combatants to uncrewed strikes, how will naval forces revise the classic Corbettian concept of sheltering a fleet-in-being during prolonged attrition conflicts?

The available evidence points toward a fundamental transition from static harbour reliance to continuous operational dispersion and active perimeter screening. Rather than relying on traditional sheltered roadsteads, navies operating in high-threat littoral zones will likely be forced to keep capital combatants continuously under way or dispersed across secondary anchorages equipped with mobile point-defence nets.
