Russia flew hundreds of warplane sorties against a small group of Ukrainian sea drones, according to the ArmyInform. The drones belong to Group 13, a Ukrainian military-intelligence unit. The unit is running out of Russian warships to sink and now strikes land targets from the sea, its commander, known by his call sign Thirteenth, said.

Years ago, Russia entered its all-out war against Ukraine with a commanding navy and treated the Black Sea as its own. A country left with almost no warships has since answered with cheap robot boats, turning expendable machines into the tool that now contests that sea.

More than 500 sorties to hunt one small drone group

Group 13 hunts Russian warships with Magura sea drones—uncrewed attack boats. Russia flew more than 500 aircraft sorties against a group of eight to 10 Magura drones at the time, the commander said. Moscow spent more on locating the drones than the unit's entire mission cost, he added. Missions have grown longer, too. What once took a day now takes three, four, or five days.

Biggest Magura sea drone doesn’t ram ships. It carries other drones and stays out seven days

The commander split the unit's rise into three stages: victory at sea, an end to Russian air dominance over the water, and now strikes on land from the sea. The bar set in 2023 and 2024 is unrealistic to hold in the Black Sea today, he said, because there are no ship targets left, and what remains is harder to reach. A struck S-400 air-defense system does not pay off like a sunk warship, he added.

The bill for Russia

The damage runs past destroyed hardware. Each Russian sailor killed leaves a family pension to pay and training to write off, the commander said. He pointed to the Syrian Express, Russia's sea supply line to Syria. It once ran a short route and now goes through the Baltic Sea, and the whole bill runs into the millions, he said.

Ukraine’s new Magura W6P naval drone won’t kamikaze—but it can patrol 1000 km

The unit's capabilities came together in a strike on the Ivan Khurs, a Russian reconnaissance ship, its first target. The later sinking of the missile boat Ivanovets killed 40 Russian crew in minutes, the commander recalled. He expects the unit to be remembered as revolutionaries, likening its sea drones to the first tanks more than a century ago.

Ukraine has unveiled the largest robot boat in its Magura sea-drone family, and this one is built to carry and launch other drones instead of ramming enemy ships, the company UFORCE told Militarnyi. UFORCE showed the new V11 during Ukraine's Independence Day drone parade, signaling a move from single-use attack craft toward a floating base at sea.

Ukraine has fought its Black Sea war with throwaway robot boats—cheap, one-way, built to hit a ship and go down with it. Shifting toward reusable platforms that keep other machines running far from any coast marks a different bet.

A floating base, not a battering ram

The V11 is the biggest drone in its class. Earlier, Magura boats were made to hit warships. This one is a transport platform that carries other unmanned systems and gear. Its main feature is the ability to launch a larger number of unmanned systems straight from its deck, turning one boat into a mobile base for them. The company refers to the drone as both the V11 and the MV11.

What the V11 can do

UFORCE says the drone carries up to 2,200 kg (about 4,850 pounds) and can stay at sea for up to seven days. The company built it for reconnaissance, surveillance, support of landing operations, and resupplying fuel and equipment to other naval drones.

"It is a platform that provides multi-domain capability: one carrier that carries and launches other unmanned systems far from shore for operations across all domains," said Oleh Rogynskyy, CEO of UFORCE.

He said the investment the company attracts works for Ukraine's Defense Forces.

From strikes to a US production line

UFORCE's design and engineering office in Portugal developed the V11, drawing on international investment and aiming at the needs of Ukraine's Defense Forces. Its work there was first reported in September 2025.

Meet the Magura W6: Ukraine’s latest threat to Russian warships

In July, the company and the US firm ReconCraft signed a memorandum for the licensed production of Magura naval drones in the US. Ukraine's Magura boats have forced Russia's Black Sea Fleet back to safer ports, and some versions have even shot down Russian fighter jets.

An explosion aboard the Eco Wizard tanker in Russia's Ust-Luga port caused an ammonia leak and is under investigation, the Russian Transportation Ministry announced on July 6.

Explosions have damaged five tankers at Russian ports since the beginning of the year.

The Russian Transportation Ministry alleged that "a minor leak of liquid ammonia" occurred at the Ust-Luga seaport in Leningrad Oblast due to "an incident" while unloading and loading the Eco Wizard tanker.

According to the Russian Telegram news channel Baza, "an explosion of an unknown nature" preceded the leak.

The ship's 23-person crew was evacuated and port emergency services are working on site to eliminate the consequences. Loading operations were stopped and emergency rescue services put on high alert. Russian Transportation Minister Roman Starovoit held a meeting on the incident and a diving inspection of the vessel is planned.

No casualties have been reported.

The Eco Wizard tanker arrived in Ust-Luga from Antwerp, Belgium on July 3, according to ship-tracking data from VesselFinder. The vessel was built in 2024 to transport liquefied petroleum gas (LPG) and flies the flag of the Marshall Islands.

The vessel is suspected to belong to Russia's "shadow fleet," a group of tankers Moscow uses to circumvent sanctions.

A week prior to the Eco Wizard explosion, a blast occurred on the shadow fleet tanker Vilamoura shortly after it visited Russian ports. The ship was carrying 1 million barrels of oil at the time of the explosion.

The Eco Wizard is the sixth tanker linked to Russia to have suffered an explosion since the start of this year.
