During the production of low-cost, high-precision strike systems (such as uncrewed surface vessels (USVs), coastal land-based anti-ship missiles, and strike uncrewed aerial vehicles (UAVs)) traditional large ships are becoming highly vulnerable targets.
On the night of August 12, Ukraine carried out a large-scale combined operation against the naval base in Novorossiysk
— the last major stronghold of Russia’s Black Sea Fleet after Russian warships had been pushed away from occupied Crimea.
For the first time in a single operation, Ukraine’s Defence Forces reportedly synchronised 15 different types of Ukrainian-made weapons, ranging from the Long Neptune missile and jet-powered drones to long-range strike UAVs and unmanned surface vessels.
According to official reports, the attack damaged four Russian warships, including Kalibr missile carriers, as well as air defence positions and port infrastructure.
The operation demonstrated the growing sophistication of Ukraine’s defence industry and its ability to compensate for limited resources through asymmetric, highly coordinated strikes rather than direct conventional confrontation with Russia. At the same time, it showed that even Novorossiysk — where Russia relocated much of its fleet as a supposedly safe haven — is no longer beyond the reach of Ukrainian weapons.
Combat operations in the Black Sea basin showed that the sea control no longer required a traditional fleet of missile cruisers or aircraft carriers.
In tandem with losing naval dominance in open waters, the Russian Federation executed a strategy of systematic economic strangulation, effectively cutting off Ukraine's traditional Black Sea exports. During the initial phase of the full-scale invasion, the Russian navy deployed a naval mine blockade and warship patrols, completely blocking maritime traffic from the ports of Greater Odesa and Mykolaiv.
After asymmetric strikes forced enemy warships to retreat from the Ukrainian coastline, the Kremlin shifted toolkits to long-range air and missile interdiction of export routes.
Unilaterally terminating the grain deal, Russia launched a massive campaign targeting the port infrastructure of the Odesa and Danube regions, conducting precision strikes with ballistic missiles and kamikaze drones against grain elevators and transshipment hubs.
Furthermore, systematic attacks on foreign civilian bulk carriers in international waters drove maritime insurance rates for shipping to critical highs, erecting artificial financial and logistical barriers for international firms.
Despite the effective operation of Ukraine’s alternative humanitarian sea corridor, air strikes against port facilities continue to prevent a full recovery to pre-war export volumes.
Prior to the full-scale invasion in February 2022, the Russian Federation massed an unprecedented naval force in the Black Sea. To establish such superiority, Moscow redeployed roughly 20 warships from other regional fleets via the Mediterranean Sea, including landing ships from the Northern and Baltic Fleets. This combined concentration of strike and amphibious landing assets posed a direct threat of large-scale landing operations along the Ukrainian coastline.
However, Turkey’s decision on February 27, 2022, to close the Bosphorus and Dardanelles Straits under the Montreux Convention effectively blocked the Russian Navy from reinforcing or rotating its Task Groups, sealing the Black Sea off from outside naval forces.
The Ukrainian Defense Forces used a multi-layered asymmetric strategy. By integrating land-based anti-ship missile complexes, long-range strike UAVs, and massed USVs, Ukrainian forces created a high-threat environment across the Black Sea Fleet's entire operational area.
Between February 2022 and April 2026, Ukrainian units conducted at least 62 successful strikes against Russian warships in the Black and Azov Seas, inside naval bases, and across open waters. That resulted in the destruction of roughly 40% of the Russian Black Sea Fleet’s major naval inventory, including flagship guided-missile cruisers, large landing craft, submarines, and escort vessels.
The primary consequence of these strikes was the forced evacuation of major surface combatants from occupied Sevastopol to Novorossiysk. Yet, Novorossiysk Bay provided only temporary sanctuary. Successful strikes against the frigate Admiral Makarov, the Sheskharis oil terminal, and the Grushovaya fuel depot demonstrated Ukraine's reach against combat units and critical port infrastructure at long ranges.
In response, Russian commanders resorted to field adaptations, such as land-based Tor-M2KM surface-to-air missile launchers directly onto the helicopter decks of Project 22160 patrol ships.
The foundational element of the Ukrainian model is a severe cost-exchange asymmetry. Traditional naval fleets are capital-intensive investments requiring years to design and build. Conversely, high-precision strike USVs cost an average of approximately $250,000 per unit.
Ukrainian sea drones evolved rapidly from kamikaze craft into multi-role combat platforms. Systems such as the Sea Baby now integrate RPV-16 thermobaric rocket launchers, laser-guided or autonomous anti-tank guided missile (ATGM) systems, and high-bandwidth satellite communications links.
Additionally, sea drones serve as mother ships for airborne FPV strike drones and relay UAVs. This in turn extends their operational reach well beyond visual line-of-sight boundaries.
Low-cost autonomous platforms force Russian surface ships to expend finite surface-to-air missiles and electronic warfare resources. This degrades shipboard defenses and creates windows for multi-domain follow-on strikes.
The degradation of Russian military capability in the Black Sea forced Moscow to rely on its "shadow fleet" of crude oil tankers to sustain export revenues. These unflagged or flag-of-convenience vessels maintain routes from Black Sea and Baltic ports toward transshipment zones in the Mediterranean and near European Union waters.
When European authorities intensified detentions of shadow fleet tankers in the Baltic Sea and North Atlantic, Moscow adapted by deploying naval combatants to escort these illegal shipments.
For example, the Project 20380 corvette Boiky, armed with Kh-35 Uran anti-ship missiles, was tracked escorting sanctioned tankers through the English Channel.
Similarly, the frigate Admiral Grigorovich escorted tanker convoys in UK waters, which only highlighted Russia's reliance on military escorts for illicit trade routes. Making combat ships to escort others turns them into targets far outside the Black Sea.
Ukraine's long-range strike doctrine has already expanded beyond the Black Sea. Operations include FPV drone strikes against the tanker Qandil, critical damage inflicted on the gas carrier Arctic Metagaz in the Mediterranean, and an attack on a Russian military icebreaker near Vyborg in the Baltic Sea (over 1,000 km from Ukraine's border).
The ability to target naval escorts in the English Channel or North Atlantic places Russia's maritime trade network at risk globally.
A direct transfer of Ukrainian combat experience to the Baltic is the joint initiative involving the German firm Stark to develop the Vanta maritime drone. The Vanta 6 USV measures 6 meters in length, reaches speeds exceeding 45 knots, features an operational range of up to 910 nautical miles, and carries a 200 kg modular payload.
Utilizing AI-driven processing and satellite data streams, the system identifies "dark vessels" (shadow fleet tankers operating with disabled AIS transponders) allowing NATO forces to monitor Baltic waters without deploying expensive destroyers or frigates.
The Black Sea campaign has drawn scrutiny from defense planners across the US, Japanese, and Taiwanese naval staffs. The Taiwan Strait is a shallow, restricted maritime environment where the People’s Liberation Army Navy (PLAN) maintains a numerical advantage in conventional warships and firepower.
Implementing the "Black Sea Blueprint" offers Taiwan a method to offset vulnerabilities, including short reaction times, early losses of traditional naval platforms, and geographic isolation.
While severe weather in the Taiwan Strait were historically viewed as obstacles for small mosquito fleets, those same conditions can be an advantage. On calm seas, a drone’s wake is easily detectable via satellite sensors and high-altitude UAVs. High seas and degraded visibility screen low-profile USVs, complicating detection by radars.
The primary objective for USVs in the Taiwan Strait is not the complete destruction of the PLAN fleet, but disrupting an assault force. Maritime drones can attack enemy craft at loading points inside mainland Chinese ports or staging anchorages before they transit outward.
Given the PLAN's multi-layered air defense networks, USV attrition during initial break-in phases will be high. However, mass deployments of low-cost uncrewed platforms force defensive networks to deplete high-cost interceptor missiles, opening vectors for shore-based anti-ship missile batteries.
Ukrainian drone manufacturers, including UFORCE, Skyeton, and General Cherry, are courting East Asian defense markets, offering systems and autonomous surface warfare doctrine to Japan and Taiwan.
The battle for the Black Sea shows the coming end of exclusively massive ship dominance. By exploiting severe cost-exchange asymmetries. Ukraine proved that sea denial no longer requires fleet parity, but cost-exchange asymmetry.
As naval service study the "Black Sea Blueprint," the main takeaway is that static naval presence is no longer a power projection tool, but a liability.
The doctrinal framework developed by the Ukrainian Defense Forces is emerging as a baseline strategy for littoral defense in restricted waters worldwide, stretching from the Baltic Sea to the Taiwan Strait, as concluded in Militarnyi's assessment of NATO tactical integration.
