Ukrainian naval forces are pioneering new forms of maritime warfare through the expanded use of remotely operated sea drones, reshaping naval combat in the ongoing conflict with Russia. Since Russia’s full-scale invasion, Ukraine has employed unmanned vessels equipped with explosive payloads and advanced weaponry to challenge Moscow’s dominance in the Black Sea, sinking approximately one-third of Russia’s Black Sea fleet.
These remotely controlled boats serve a variety of functions, from carrying surface-to-air missiles capable of downing enemy aircraft to deploying aerial attack drones. Last month, a Ukrainian drone reportedly engaged in a rare drone-on-drone water skirmish with a Russian counterpart, marking a new chapter in naval engagements. Another notable innovation included the deployment of a four-wheeled remote-controlled ground vehicle armed with a machine gun during an amphibious assault on a Russian-held peninsula, a first of its kind in modern warfare.
Though unmanned naval vessels are not exclusive to Ukraine—Yemen’s Houthi rebels deployed a similar drone boat against a Saudi frigate nearly a decade ago, and the United States recently used unmanned aircraft in rescue and attack operations—Ukraine’s extensive use and success of these systems against a much larger conventional navy have drawn international interest. Military analysts from regions as diverse as Taipei and Tallinn are studying Ukraine’s approach as a potential model for their own defenses.
Experts emphasize that while drone technology provides valuable capabilities, it does not replace traditional naval forces entirely. “Drones are tools in the tool kit,” said a professor at the U.S. Naval War College, underscoring their utility without fundamentally altering naval strategy.
The relative affordability and accessibility of Ukraine’s drone fleet have spurred a surge of innovation, with at least 27 Ukrainian companies actively developing new maritime platforms and technologies. According to the director of Ukraine’s Unmanned Naval Association, the cost-effectiveness of water drones offers a strategic advantage that can provide security at a fraction of traditional naval expenses.
Ukraine’s advancements have attracted foreign collaboration and investment. The Ukrainian company UFORCE, which produces the Magura sea drones—Ukraine’s first kamikaze maritime drones—recently entered into a joint venture with a U.S. firm to begin production stateside. Additionally, the Norwegian defense giant Kongsberg established a presence in Ukraine and has partnered with local manufacturers of the Sargan sea drones. Other countries in Northern Europe and Asia, along with Gulf states, have expressed interest in acquiring or developing similar capabilities.
Given Ukraine’s geographic position, where air defense benefits from layered protection inland, basing defensive systems at sea offers crucial early warning and interception opportunities against threats such as Iranian-designed Shahed drones. Experts note that the rapid development cycles and replaceable nature of these drones contribute to their appeal in modern maritime defense.
The development of Ukraine’s sea drone program has been marked by persistent trial and error. Initial models were adapted from civilian motorboats and underwent rigorous testing and frequent repairs, reflecting iterative progress on the front lines. Units operated by Ukraine’s military intelligence agency have combined maritime drones with aerial attack drones launched from the sea platforms, effectively functioning as miniature aircraft carriers to strike Russian coastal radar installations and disrupt enemy defenses.
These tactics were instrumental in Ukrainian operations against Russian seaports such as Taupse and Novorossiysk. Additionally, in April, Ukraine’s 412th Unmanned Systems Brigade successfully used sea-launched interceptor drones to shoot down two Russian Shahed drones, underscoring the expanding versatility of unmanned naval systems.
Ukrainian commanders emphasize the importance of adaptability and the human element in drone warfare. “Technology is not what matters most,” said Lt. Col. Yuriy Kochevenko, commander of the 412th brigade’s sea battalion. “People are.”
As Ukraine continues to refine its drone capabilities, the innovations emerging from its conflict with Russia are influencing naval strategies worldwide and illustrating a shift toward more cost-effective, technologically driven maritime defense options.
