The commander of sea-drone operations for Ukraine’s military intelligence agency says more complex strikes against Russian forces are expected next year, after Kyiv’s uncrewed fleet succeeded in curbing the movements of Russia’s once-dominant Black Sea navy.

In an interview with The Associated Press, the head of the specialized maritime drone unit, Group 13, said Ukraine’s attacks have forced Russia to adapt, limiting opportunities for major Black Sea strikes seen earlier in the war.

“Today, we’ve likely reached a plateau,” said the officer, who is identified only by the call sign “13th” under Ukrainian military protocol.

“We are effectively limiting the enemy’s movements, but those dramatic, high-profile strikes we saw earlier haven’t happened for quite some time. That’s because the enemy has adapted.”

Last month, Ukrainian officials said sea-attack drones were used in strikes against vessels in Russia’s sanctions-evading “shadow fleet” of oil tankers. The commander declined to comment on those operations.

The officer said Russian naval vessels “barely operate,” often venturing only up to 25 miles (40 kilometers) from port to fire missiles before retreating. “They constantly hide. And in a way, that’s also a result of our unit — because you can imagine the cost of maintaining a fleet that cannot operate at sea.”

The officer spoke in uniform, his face covered and eyes obscured by tinted glasses. For security reasons, the intelligence agency asked that the location and other details of the interview not be disclosed.

Drone technology has become vital to Ukraine’s military, offering inexpensive tools for reconnaissance and strikes in countering Russia’s invasion. Its two sea-drone programs are run separately by its military and domestic intelligence services.

Group 13 operates the Magura family of sea drones, which Ukraine credits with multiple strikes on Russian ships.

The unit currently deploys two variants — the V5, a smaller ramming drone, and the larger V7, a weapons platform. Both are controlled remotely using suitcase-sized consoles equipped with joysticks, screens and safety switches.

At a recent demonstration, operators showed a V7 fitted with modified U.S.-made Sidewinder air-to-air missiles. In May, the intelligence agency said a Magura drone shot down a Russian fighter jet — a development the commander called a “breakthrough” in maritime warfare.

He said the next stage of Ukraine’s drone evolution will rely on deeper integration of artificial intelligence, using a growing archive of operational video and sensor data to improve targeting and reduce operator workload.

“Right now, target search is a combined process — part operator, part AI,” he said. “In the future, you’ll launch the drone and it will independently search for a target, distinguish civilian vessels from military ones, and make more of the decisions.”

Ukraine’s military, he added, had a “huge amount” of operational data available to further train AI models.

Although he did not comment on specific development plans within the intelligence agency, 13th said countries exploring longer-range strike options, submersible drones and more complex mixed-fleet operations see such systems as a logical next step.

Ukraine is also seeking to expand co-production of drones with several NATO countries next year.

During a visit by President Volodymyr Zelenskyy to Athens last month, Kyiv and Greece announced plans for joint work on maritime uncrewed aerial vehicles (UAVs), expanded training and exercises, and information-sharing on maritime threats.

Despite Russia’s adjustments, the commander said Ukraine’s sea-drone program remains effective.

“We’re working on many fronts to change this situation and create a turning point,” he said. “For now, I can say this: We haven’t lost effectiveness. We’ve simply reached a point where we’re holding the enemy in check.”
