US negotiators have quietly kept a deal to let Ukraine help build Patriot interceptor missiles alive, even after US President Donald Trump publicly cast doubt on it, Reuters reported. Four people familiar with the talks said Washington never ordered them stopped. Ukraine, running low on air defenses, urgently wants the missiles to blunt Russia's growing ballistic strikes.

Russian daily drone attacks forced Kyiv to chase air defense from every direction at once, including home-grown interceptors. But this year, Moscow has increasingly turned to ballistic missiles, the hardest weapons for Ukraine to stop. US-supplied PAC-3 interceptors fired by Patriot systems are among the few weapons that can reliably shoot them down, and Ukraine has now run out.

The talks Trump seemed to kill

Last week, Trump appeared to reverse course, telling reporters the US had not agreed to let Ukraine build Patriots and must be "very careful about letting somebody build them." 

According to Reuters, two sources tied that to a tense White House meeting with Zelenskyy. Yet the negotiations pressed on. 

"No order was given to halt the discussions," one source said, adding that talks continued with US arms makers and military officials.

Matthew Whitaker, Washington's envoy to NATO, is leading the drive for a deal. He visited Kyiv last month to weigh options with Ukrainian officials and weapons executives. His spokesperson framed the trip around drone collaboration that would benefit US forces, without naming the Patriot plan. 

A senior administration official told Reuters that any agreement must protect US technology.

What Ukraine could build

The options include making Patriot components in Ukraine and shipping them to Germany for final assembly, the sources said. A US official called that the most feasible route. Germany already produces an older Patriot model, and the advanced PAC-3, the newest Patriot interceptor, is expected to follow.

Ukraine could instead join an existing US-European Patriot program, or build a cheaper version of the PAC-3. 

It might also tap Lockheed Martin's new lower-cost interceptor, the PAC-3 ACE, unveiled last month.

A promise made, then pulled back

During a meeting with Zelenskyy in Ankara last month, Trump said the US would license Ukraine to make PAC-3s. His later reversal caught many off guard, including Zelenskyy. In a follow-up call, US Vice President JD Vance assured him that deals between presidents would hold, one source said.

Ukraine's clock is running

Even with a deal, Ukraine would not receive newly built interceptors for a year or more. So Kyiv is urging allies to hand over some of theirs and exploring swaps to get missiles sooner. 

Earlier, Zelenskyy warned that Ukraine had run out of Patriots. That day, it intercepted just one of 27 ballistic missiles Russia fired. 

Global stocks of high-end interceptors have shrunk since the Iran war, with Patriots once bound for Ukraine diverted to US forces and Gulf allies.

German security services believe Russia was preparing to assassinate the head of a company that supplies drones to Ukraine, according to Die Zeit. Two suspected agents who surveilled him have been arrested, and officials warn the case marks a deadlier turn in Russian operations inside Germany.

Surveillance of a drone-maker

Investigators say the target is Stefan Thumann, head of the Bavarian startup Donaustahl, which makes reconnaissance and kamikaze drones for Ukraine. In December 2025, a recruit filmed his home and photographed the nameplate, focusing on the man rather than the company, security services believe. Thumann has been outspoken against Moscow, posting that "Russia doesn't want peace. It wants the destruction of the West."

Two arrests

A foreign intelligence service flagged Thumann as high-risk in December 2025. Bavarian police arrested Serhii N., a former bricklayer from Kharkiv with no intelligence training, then released him before analyzing his phones. The devices later showed contact with Russian intelligence and attempts to trail his father, investigators found. He fled to Spain, and a Romanian woman, Alla S., continued the surveillance. Both were arrested in March 2026, in Spain and North Rhine-Westphalia.

Fourth suspect arrested in arson attack on Czech factory that made drones and thermal optics for Ukraine

Russia recruits such disposable agents online, paying people from precarious backgrounds for surveillance, arson, and sabotage, and discarding them afterward. Ukraine's own SBU security service has reported dozens of cases in 2026 of Russia recruiting Ukrainians at home for arson and sabotage, often by forging Ukrainian security summonses to pose as their own government.

The BfV, Germany's domestic intelligence service, classifies the case as a suspected planned assassination. A federal investigating judge was not convinced, so the arrest warrant cites only suspected intelligence-agent activity. Lawyers for both suspects declined to comment.

A widening threat

A second German arms company is reportedly in Russian intelligence's sights, investigators say. On 11 June, Serbian officers stopped a truck of concealed explosives apparently bound for Bavaria, home to Donaustahl, Quantum Systems, and Helsing. 

The threat has precedent: agents had Rheinmetall chief Armin Papperger watched in 2024, and an FSB killing struck a Georgian exile in Berlin in 2019. It fits a broader Russian sabotage campaign across Europe. 

Thumann, now under guard, still taunts Moscow: 

"You won't break me."
