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.

Ukraine's defense minister raised the urgent need for Patriot interceptors with Sweden on 22 October, the Defense Ministry reported. The same day, President Volodymyr Zelenskyy warned of more Russian ballistic strikes and blamed US supply cuts.

Patriots are Ukraine's main defense against Russian ballistic missiles, and their deliveries keep shrinking. Figures Zelenskyy released in August showed Patriot interceptor deliveries falling from 675 in 2023 to 364 in 2025, with 264 projected for 2026. Europe holds enough PAC-2 and PAC-3 interceptors for Ukraine's minimum winter needs, Zelenskyy told journalists on 16 October, but he did not yet know how many Europe would hand over, Ukrainska Pravda reported.

Partners' stocks now, Ukraine's missiles later

Russia fired 21 ballistic missiles at Kyiv overnight on 22 October, Zelenskyy said. Defense Minister Yevhenii Khmara told his Swedish counterpart, Pål Jonson, that Ukraine must counter ballistic threats as fast as possible, in particular with Patriot interceptors.

1,000 Patriot missiles arrive too late for this winter, so Ukraine asked the Ramstein arms coalition to open its warehouses

The ministry's readout says Ukraine has Patriot missiles under contract. It also says Kyiv asks partners to transfer interceptors from their stocks in exchange for future deliveries allocated to Ukraine.

Khmara made the same request at the Ukraine Defense Contact Group meeting on 8 September. He said then that Ukraine was contracting about 1,000 Patriot missiles with partners' help and an EU loan, but they would arrive only in the coming years, LB reported. He asked allies for missiles from their stocks now, in exchange for future upgraded missiles under Ukraine's contracts.

"Only when the American side approves it"

Zelenskyy spoke to journalists before meeting Finnish Prime Minister Petteri Orpo, Ukrinform reported. He said the Americans had reduced supplies and Russia would step up ballistic attacks.

"Europeans can provide the missiles only when the American side approves it," Zelenskyy said.

He said the US had sent most of its interceptors to the Middle East.

On 19 October, Zelenskyy told US senators that US Defense Secretary Pete Hegseth was not signing off on Patriot deliveries allies had already paid for. Axios obtained the call transcript from Ukrainian officials. A US government official told the Kyiv Independent that Ukrainian officials' claims that Hegseth was holding up the missiles were "not true."

Washington says nothing has changed. "We have our own needs, too," Secretary of State Marco Rubio said on 20 October, but there is "nothing being deliberately denied to Ukraine." Hegseth told reporters in Eau Claire, Wisconsin, that the US had not changed its posture toward Ukraine, "but certainly with things like interceptors, we want to make sure our guys have the most possible as well."
