Undercover reporters ordered 500 drone mesh modems from a Chinese firm, which billed them to Russia’s Alabuga drone plant, investigation by The Insider found. The outlet estimates the firm makes about half the high-power mesh modems that let Russia steer its drones deep into Ukraine. The firm’s director also named US company AMD as the source of a key chip, and AMD says it has not sold to the firm.

Geran drones and Banderol drone-missiles have become Russia’s main weapons against Ukraine’s energy grid. Russia began this winter’s strike campaign against that grid in late September, ISW assessed. Ukrainians’ survival this winter depends largely on how fast the West halts mesh modem sales to Russia, the outlet argued.

What a mesh modem does

A mesh modem links drones into one radio network. Each unit relays data for the others, so if one drone is shot down, traffic reroutes through the rest. Information keeps flowing even if nearly 80% of the drones are downed, Ukrainian defense adviser Serhii “Flash” Beskrestnov said in November 2025.

Range is the other half of the threat. One XK F-359 holds a line-of-sight link over 100–300 km, The Insider says. In theory, a couple of relay drones could keep a whole attack on Kyiv connected. Operators can then send new commands in flight and steer around air defenses. Russia’s Gerbera drones, first built as cheap decoys, increasingly carry these modems.

A modem from an upgraded Gerbera

To trace the part, The Insider’s correspondent in Ukraine examined an unmarked mesh modem from an upgraded Gerbera with a vertical tail fin, a version that appeared this summer. The outlet identified it as Xingkai’s XK F-359, the part Ukrainian intelligence and earlier reporting, Euromaidan Press included, had logged as the XK-F358. The Insider calls that label a misidentification.

Next, The Insider and the Nordsint investigative project contacted Xingkai on WeChat, posing as a Russian military supplier based in Alabuga. A company employee who introduced himself as “Jack Jiang” confirmed the firm is the model’s sole maker. The Insider identified him as Jiang Qin, Xingkai’s director and owner.

500 modems, three banks

The reporters then ordered 500 units for delivery to Alabuga, home to the plant that makes most of Russia’s long-range drones. Jiang invoiced 19.5 million yuan, which The Insider put at about $2.87 million. He offered two ways to pay: dollars to Xingkai’s DBS Bank account in Hong Kong, or yuan to his personal Ping An Bank account.

In the chat, the reporters said outright that the end user was a military production facility. Jiang raised no objection, The Insider reported.

Later, after the reporters asked to update the address, Xingkai sent a revised invoice with “Alabuga” spelled in Latin letters. This time, it routed payment to a China Merchants Bank account in the name of a former Xingkai manager. She left a management post at the company in 2025, according to Tesari corporate records cited by The Insider. None of the three banks answered The Insider’s requests for comment.

Jiang also claimed the modem’s programmable chip is made by AMD. Asked for an AMD license, he refused, saying Xingkai buys the chips through a middleman. AMD told The Insider that Xingkai “is not an AMD customer or authorized partner,” and said it had sold the company nothing. AMD added that it bars exports of its products to Russia that violate US export controls and sanctions.

A Russian drone strike sank the Comoros-flagged cargo ship Khoryv in the Black Sea near Romania’s port of Constanța on 23 October, killing a Ukrainian sailor and leaving three crew members missing. Nine others were rescued, Digi24 reported.

The sinking comes amid a surge in attacks on commercial shipping near Romania and Bulgaria, threatening civilian crews and routes used to transport Ukrainian agricultural exports. As Russia intensifies strikes on Ukrainian ports and shipping, the Danube corridor and nearby waters have become increasingly important to Ukraine’s maritime trade.

Romanian President Nicușor Dan blamed Russia for the attack, describing it as part of Moscow’s escalation of the war against Ukraine and its attacks on NATO’s eastern flank, Reuters reported. 

Ukraine’s Foreign Ministry confirmed to Radio Svoboda that a Ukrainian citizen was among those killed.

Ukrainian sailor killed, three crew members missing

The Khoryv sent a distress signal at around 10 a.m. local time, about 13 nautical miles (24 kilometers) east of Constanța, just outside Romania’s territorial waters, Digi24 reported. The vessel caught fire, sustained major damage, and capsized, with only a small part of its hull remaining visible above the water.

Romania’s naval authority said 13 crew members were aboard: 10 Ukrainians and three Azerbaijanis. Rescue teams recovered nine sailors alive and one body, while three crew members remained missing, Reuters reported.

Ukraine’s Foreign Ministry said the vessel had been traveling from a Turkish port and confirmed that the Ukrainian Embassy in Romania had received information from Romanian authorities about one Ukrainian sailor’s death. Four Ukrainian survivors, including the captain, were taken to a hospital, while two others did not require medical assistance.

Attacks threaten Black Sea shipping

The sinking comes amid a surge in attacks on commercial vessels off the coasts of Romania and Bulgaria. At least seven cargo ships have been hit over the past two weeks, with around 30 sailors reported dead or missing, according to Reuters.

The vessels targeted in recent incidents were either anchored near or heading toward the Sulina Canal, which connects the Danube River to the Black Sea. The canal has become a key export route for Ukraine, one of the world’s largest exporters of grain and vegetable oils.

Ukraine has increasingly relied on Danube ports and routes through Romanian territorial waters as Russia attacks its own Black Sea ports. Strikes on commercial vessels threaten crews and risk disrupting Ukrainian agricultural exports to international markets.

Russia has intensified attacks on Ukrainian ports and ships traveling to or from Ukraine. Moscow has described its strikes on vessels as retaliation for Ukrainian attacks on Russian or Russia-linked ships.

NATO plans stronger Black Sea surveillance

NATO said on 20 October it would send additional maritime patrol aircraft, radar systems, and drones to the Black Sea following the attacks on commercial shipping, according to Reuters. The alliance has not specified which capabilities it will deploy.

Romania, Ukraine, and Bulgaria have called on NATO to do more to protect commercial vessels. The latest sinking adds urgency to those calls as attacks increasingly affect shipping near NATO territory.

The latest incident highlights the growing risks to commercial shipping as Russia’s war against Ukraine increasingly affects maritime traffic beyond Ukraine’s own coastline.
