Ukraine's maritime strategy targets the global infrastructure of Russian oil
In short: To bypass Western sanctions, Russia built a 'shadow fleet' of roughly 1,000 vessels to move energy. Now, Ukraine is systematically dismantling this network using advanced unmanned drones and underwater explosives, turning international waters into a high-stakes theater of unconventional maritime warfare.
By 2025, Ukraine's naval approach underwent a major transformation, pivoting from standard maritime methods to strike the 'shadow fleet.' This group comprises around 1,000 ships utilised for moving Russian petroleum while bypassing G7 price limits and global sanctions. By striking these assets, Ukraine aims to degrade Russia's petrodollar income. Key tools in this campaign include 'Sea Baby' unmanned surface vessels, which feature AI-assisted targeting and a range of 1,500 kilometers, and 'Sub Sea Baby' drones designed for underwater operations against submerged targets.
The geography of these strikes is expanding rapidly. While many operations occur in the Black Sea, Ukraine has extended its reach into the Mediterranean and the Sea of Azov. Notable incidents include the sinking of the 9500-ton freighter Ursa Major off Spain in December 2024 and the 164,000-ton super tanker Koala in February 2025. In late 2025, Ukraine launched 'Operation MoLoChKa,' a multi-day campaign in the Sea of Azov that hit over 100 vessels before expanding into the Black Sea.
The geopolitical implications are complex. While the Trump administration reportedly approved intelligence sharing for these strikes, viewing them as a tool to pressure the Kremlin, other nations have expressed concern. Turkey has condemned the attacks for threatening maritime safety and environmental protection within its exclusive economic zone. Russia has responded with threats to isolate Ukraine from the sea and has conducted retaliatory strikes on Turkish-owned cargo ships. These actions highlight a shift toward 'unconventional warfare' that hits economic infrastructure without necessarily triggering a direct open conflict with Western powers.
Technological innovation is central to this shift. Engineered for repeated deployment instead of one-off destruction, the Sea Baby system enables continuous activity via portable command hubs. These systems, partially funded through public fundraising, represent a distributed civil-military approach to modern warfare, where low-cost autonomous tech is used to challenge large-scale state maritime interests.
