A Ukrainian jamming-systems maker went to a US Army base to do to candidate drones what Russia does to Ukraine's: flood them with electronic warfare (EW) and see which survives. Unwave company has tested four of its EW systems at Fort Carson in Colorado as part of the Pentagon's Drone Dominance program and has been asked to continue supporting it.

The Pentagon is using Drone Dominance to choose the drones it will buy at scale, more than 200,000 by 2027, and it needs to know they work under jamming, the condition that decides most drone fights in Ukraine.

So it brought in a Ukrainian electronic-warfare maker to supply that jamming, turning Ukraine's hard-won counter-drone experience into the test bench for American hardware. It follows a pattern in which US defense efforts adopt Ukrainian battlefield models.

Ukraine brings the jamming

From 24 August to 2 September, Unwave's team worked at the base, running scenarios that pitted its jammers against drones tasked with protecting fixed positions, moving vehicles, and infrastructure.

The crews operated from three separate positionsat short and long range to compare how drones from different manufacturers held up.

"Our mission was to create conditions as close to the real battlefield as possible," the company said, adding that it judged the tasks successfully completed but could not detail the scenarios for security reasons.

In all, 14 drone makers and three electronic-warfare firms took part.

Four systems on show

Unwave brought four:

• VIHA, which it calls Ukraine's first tactical-operational jammer for directed suppression of drones
• BOOMBOX, built to shield troops and positions from FPV and drop-drones
• SHATRO, for vehicles
• CHOVEN-2, a multi-frequency amplifier for cars.

Its participation was organized by Revenant Technologies, a US firm that specializes in bringing combat-proven defense tech to the American market, and helped design the scenarios using its ties to Ukraine and frontline experience.

A foothold in the US market

For Unwave, the value is a door into the alliance's security architecture. The event showed the importance of Ukrainian, American, and European specialists testing together, the company said, and "such interaction will help integrate Ukrainian technologies into the security architecture of our allies."

Ukrainian drone makers are getting another shot at a Pentagon contract, this time for bomber drones. Seventeen companies, including Ukrainian firms and Western partners fielding Ukrainian designs, will test bomber drones at Camp Grayling in Michigan in October, the next stage of the Pentagon's Drone Dominance program, Defender Media reported.

The Phase 2.5 Bomber Qualifier is the latest round of the Pentagon's drive to buy combat-tested drones at scale, and Ukrainian makers are again in the field, some through US-registered partners, because Pentagon rules bar direct sales from foreign firms.

This time, the target is bombers, the drones that drop munitions on what is below them.

Seventeen makers head to Michigan

The contest runs at Camp Grayling, a Michigan training range, and organizers call it the hardest and fastest-paced stage of the program yet. Each company must bring at least six fully built systems.

The testing splits into two parts: a Bomber Qualifier, which the makers conduct themselves, and a Bomber Gauntlet run by US soldiers. Organizers have not published details of a third mission. Winners of the wider program earn Pentagon supply contracts.

Ukrainian bombers make the list

The invited firms include UFORCE USA Services, Grim Tech, Gurzuf Defence, UA Defense Tech, Skycutter, and UDD Tech Corp. Which models they will bring is not yet clear.

UFORCE is known for its Nemesis bombers. Grim Tech showed a light bomber, the Grim-18, at the MSPO defense expo in Poland this month, and Gurzuf builds heavy bombers, including the Ayudag-6, which recently set a Ukrainian payload record for multirotor drones at 130 kilograms.

A second try after a US sweep

In the program's last phase, the Pentagon picked five winners in each of two categories, and all were American, though a Ukrainian firm had reached the second round and, by industry accounts, Ukrainian designs were incorporated into some Western entries. For Ukraine's makers, the bomber round is another chance to turn battlefield-proven hardware into a US contract.

Ukraine's battle-tested drone makers did not win a single top slot in the Pentagon's latest drone contest. But some Ukrainian technology won anyway, competing quietly under the names of Western partners, The Defender Media reports.

The Pentagon's $1.1 billion Drone Dominance program does not allow direct purchases from Ukrainian firms, which must set up a US legal entity to bid.

The Ukrainians who competed under their own names were hampered by export licenses, the hunt for non-Chinese components, and visa issues, and none of the four cracked the top five in either category.

American firms sweep the top slots

The Pentagon picked five winners each in two categories, long-range strikes out to 15 kilometers and close-in assault. Eric Schmidt's Perennial Autonomy topped the long-range field with its Hornet drone, on 80.1 points, and Neros led the close-in category with 88.1. Neros already supplies Ukraine with 6,000 of its Archer FPV drones.

The rest of the winners, from ORQA's US arm to XTEND and ModalAI, were American as well. All will receive Pentagon supply contracts, with order sizes to be set later.

Ukrainians win under other flags

The Ukrainian firms that announced their entries, F-Drones, General Chereshnya, Grim Tech, and Stellarion, all missed the cut, though General Chereshnya had reached the program's second round earlier in the year.

Bureaucracy tripped the open entrants

Stellarion laid out what went wrong. Getting export permits and moving hardware took so long that integrating American parts, including warheads, and adapting the finished system on schedule became "complicated," its representatives said.

Finding NDAA-compliant, non-Chinese components ate up more time, and visa delays kept its specialists from fixing technical problems on site.

Firms that missed the top five can enter later rounds: a Gauntlet 2.5 contest for bomber drones is set for October, and a third phase begins in February 2027, with missions built to test control of several drones at once.

U.S. President Donald Trump brushed off a reporter's question on July 3 about pausing weapons deliveries to Ukraine, claiming Washington is "giving weapons" to Kyiv.

The Pentagon previously confirmed that the U.S. has already halted some military aid shipments to Ukraine in order to conduct what it calls a "capability review" of its own stockpiles.

"Why did you pause weapons shipments to Ukraine?" a reporter asked Trump as the president prepared to board Air Force One.

"We haven't," Trump replied. "We're giving weapons."

Trump then offered a contradictory answer, saying the U.S. is "trying to help" Ukraine while also claiming that former U.S. President Joe Biden depleted the country's weapons stocks with military aid to Kyiv and that Washington must defend its own interests.

"But we've given so many weapons — but we are giving weapons, and we're working with (Ukraine), we're trying to help them," Trump said.

"But we haven't... You know, Biden emptied out our whole country giving them weapons and we have to make sure that we have enough for ourselves."

Trump then asked the reporter which media outlet he represented.

"The New York Times," the journalist said.

"Ah, no wonder," Trump replied.

Ukraine scrambles to clarify extent of US military aid pause and ‘whether everything will continue’

When the U.S. Department of Defense (DOD) halted the transfer of critical air defense missiles and other weapons to Ukraine, Kyiv and its partners were caught off-guard and are now left scrambling for clarity on the scope and length of the Trump administration’s decision. The White House confirmed the halt after a July 1 report by Politico said shipments were paused due to concerns over the size of domestic stockpiles. The decision “was made to put America’s interests first following a DOD rev

Reports that the U.S. had suddenly paused some weapons shipments — including deliveries of desperately needed air defense missiles — left officials in Kyiv scrambling for answers. Trump's response provides little clarity and even less reassurance to Ukrainians facing increasingly deadly Russian missile attacks night after night.

The decision to halt the shipments "was made to put America's interests first following a (U.S. Defense Department) review of our nation's military support and assistance to other countries across the globe," White House Deputy Press Secretary Anna Kelly said in a statement after Politico broke the story on July 1.

The Washington Post later reported that a shipment of U.S. weapons, including advanced air defense systems and precision missiles, was halted in Poland where it was awaiting delivery to Ukraine.

U.S. State Department Spokesperson Tammy Bruce, like Trump, insisted that the U.S. was not pulling support from Ukraine.

"This is not — I will reinforce this — this is not a cessation of us assisting Ukraine or of providing weapons," Bruce told reporters at a briefing.

"This is one event in one situation, and we'll discuss what else comes up in the future. But be wary of painting too broad a brush there."

Trump's remarks about the weapons shipments followed an update on his July 3 phone call with Russian President Vladimir Putin.

"We had a call. It was a pretty long call. We talked about a lot of things," he said.

Their conversation brought the Kremlin no closer to agreeing to a ceasefire, according to Trump.

"No, I didn't make any progress with (Putin) today at all," he said.

U.S. weapons already in Poland en route to Ukraine have been halted, including advanced air defense systems and precision missiles, the Wall Street Journal reported on July 2.

The Pentagon confirmed the halt in a July 2 briefing, citing an ongoing "capability review" aimed at ensuring U.S. military assistance "aligns with its strategic defense priorities."

The shipment in Poland includes over two dozen PAC-3 Patriot missiles, more than two dozen Stinger air-defense systems, Hellfire air-to-ground missiles, and over 90 AIM air-to-air missiles intended for use with Ukraine's F-16 fighter jets, according to U.S. administration and congressional officials cited by the Wall Street Journal.

"We see this as a common-sense, pragmatic step towards having a framework to evaluate what munitions are sent and where," Pentagon spokesperson Sean Parnell said.

The decision has sparked backlash from both sides of the political aisle in Washington. Republican Rep. Brian Fitzpatrick, co-chair of the Congressional Ukraine Caucus, called the pause "unacceptable," while Democratic Senator Richard Blumenthal labeled it "fallacious and maybe even disingenuous."

The pause comes at a critical moment for Ukraine, which faces intensified Russian missile and drone strikes. On June 29, Russia launched the largest aerial assault against Ukraine since the start of its full-scale invasion in February 2022, targeting civilian infrastructure and cities far beyond the frontline.

NATO Secretary General Mark Rutte, speaking on July 2, emphasized the urgency of continued Western support for Kyiv. "I totally understand that the U.S. always has to make sure its interests are covered," he said. "But in the short term, Ukraine cannot do without all the support it can get."

The Pentagon has not provided a timeline for when the held-back shipments might resume.

‘Major casualties among civilians’ — US freeze on air defense missiles is terrible news for Ukraine

The halting of deliveries of air defense missiles from the U.S. will lead to“major casualties among civilians,” a deputy commander in Ukraine’s air defense told the Kyiv Independent. Politico reported on July 1 that the U.S. Defense Department (DOD) had halted shipments of some weapons previously

Pentagon spokesperson Sean Parnell confirmed on July 2 that some military assistance to Ukraine has been halted as the U.S. Defense Department conducts a review of foreign aid deliveries.

"This capability review... is being conducted to ensure U.S. military aid aligns with our defense priorities... We see this as a common-sense, pragmatic step towards having a framework to evaluate what munitions are sent and where," Parnell said.

The White House earlier confirmed the pause in shipments, citing a broader reassessment of U.S. military stockpiles amid media reports of the halt in military assistance.

The weapons reportedly being held back include two dozen Patriot air defense missiles, over two dozen Stinger air-defense systems, precision artillery rounds, Hellfire missiles, drones, and more than 90 AIM air-to-air missiles launched from F-16 fighter jets.

New U.S. military aid packages have not been approved since U.S. President Donald Trump was inaugurated in January, raising concern among Ukraine's allies.

"Ultimately, our job here at the Department of Defense is to pursue the president's 'America First' agenda and make sure that we achieve peace through strength throughout the world," Parnell said at a Pentagon press briefing.

The U.S. Defense Department will not provide updates on the timeline and quantity or type of munitions provided to Ukraine, he added.

"What we've done here at the Department of Defense is create a framework to analyze what munitions we're sending (and) where," Parnell said.

A bipartisan group of U.S. lawmakers has voiced their opposition to the decision to halt military aid shipments to Ukraine.

"We must build up our own Defense Industrial Base here in the U.S. while simultaneously providing the needed assistance to our allies who are defending their freedom from brutal invading dictators. To not do both is unacceptable," Republican Rep. Brian Fitzpatrick, the co-chair of the Congressional Ukraine Caucus, said.

Democratic Senator Richard Blumenthal, a member of the Senate Armed Services Committee, described the military aid pause as "fallacious and maybe even disingenuous."

NATO Secretary General Mark Rutte said on July 2 that he understands the White House's need to safeguard its own defense capabilities, but underscored that Ukraine urgently requires sustained support.

"I totally understand that the U.S. always has to make sure its interests are covered... When it comes to Ukraine, in the short term, Ukraine cannot do without all the support it can get," Rutte said.

The Washington Post reported that the military aid was already in Poland, being prepared for delivery to Ukraine.

‘Major casualties among civilians’ — US freeze on air defense missiles is terrible news for Ukraine

The U.S. Defense Department (DOD) has halted shipments of some air defense missiles and other weapons previously promised to Kyiv out of concerns over the size of U.S. stockpiles, Politico reported on July 1, citing sources familiar with the matter.

The suspension comes as Ukraine faces a shortage of air defense munitions along with increasingly intense and deadly Russian bombardments. In June 2025, Russia launched 5,337 Shahed-type drones at Ukraine, shattering its previous monthly record.

Pentagon policy chief Elbridge Colby made the decision to pause the aid deliveries after conducting a review of U.S. munitions stocks, three sources told Politico. Colby was reportedly concerned about dwindling levels of artillery rounds, air defense missiles, and precision munitions.

Among the items being held back from Ukraine are Patriot air defense missiles, precision artillery rounds, Hellfire missiles, drones, and other missiles that Ukraine launches from F-16 fighter jets.

Colby made the decision in June, amid a surge in Russian mass aerial attacks against Ukraine. The White House later confirmed the pause.

The Pentagon's decision "was made to put America's interests first following a DOD review of our nation's military support and assistance to other countries across the globe," White House Deputy Press Secretary Anna Kelly said in a statement issued after Politico published the story.

"The strength of the United States Armed Forces remains unquestioned — just ask Iran," she said.

Since his inauguration in January, U.S. President Donald Trump has not approved any additional military aid packages for Ukraine. Defense Secretary Pete Hegseth also announced recently that the U.S. will reduce the total aid it sends to Ukraine in its upcoming defense budget.

At the NATO summit in The Hague in late June, Trump said he would "see" if the U.S. could supply Kyiv with additional missiles for its Patriot systems.

"They (Ukraine) do want to have the anti missiles, as they call them, the Patriots, and we're going to see if we can make some available," he said after meeting with President Volodymyr Zelensky.

"They are very hard to get. We need them too. We are supplying them for Israel, and they are very effective."

But according to a source who spoke to Politico, plans to reduce and redirect air defense munitions and other weapons for Ukraine have been in the works for months. The administration is looking to redirect artillery shells, tank shells, and air defense systems to Israel or back to Washington.

"They have proposed repeatedly since March to pause the shipments," the person said.

Colby, the reported architect of the decision, has previously advocated for reducing U.S. military assistance to Ukraine to prioritize deterrence efforts in Asia.

Russia on June 29 launched the largest missile and drone attack against Ukraine since the start of its full-scale war.
