Ukraine has loosened its reliance on Washington but still depends on the United States in three military areas that let US President Donald Trump keep pressuring Kyiv, The Telegraph wrote on 12 October. That pressure now centers on the energy ceasefire Trump declared on 11 October, with US officials reportedly warning Kyiv not to hit Russian energy during the truce. Kyiv backs a mutual truce, but Moscow has not confirmed it, and Russian strikes on Ukraine’s grid have continued.

The paper named three such ties: satellite intelligence, Patriot interceptors, and American weapons bought with European money. A pause in any of them would hit just as Russia’s winter campaign begins. Ukraine says an intercepted document reportedly lays out up to 1,000 Russian missiles, drones, and bombs for 60 critical sites this winter, so any pause in US intelligence, interceptors, or PURL deliveries would land as that campaign gets under way.

Satellite intelligence: the US still holds the key

The Central Intelligence Agency (CIA) and other US services still pass precise satellite data that help Ukrainian forces hit targets inside Russia, by the paper’s estimate. Trump briefly suspended that flow in March 2025 to pressure Zelenskyy. A Ukrainian official told Axios that Trump envoys Steve Witkoff and Jared Kushner threatened during 9 October talks in Miami to cut off US intelligence.

Patriot interceptors: no quick substitute

The Telegraph called interceptor missiles the second and probably sharpest dependency. Only American Patriot systems can down Russia’s most powerful missiles, which strike Ukrainian cities daily, the paper wrote. Kyiv’s PAC-3 stocks ran dry mainly because US reserves were diverted to the Middle East after America’s war against Iran, the paper added. Kyiv had warned in March that a long Middle East war would squeeze its PAC-3 supply.

Five European defense firms—Destinus, MBDA Deutschland, Safran, Airbus, and Thales—signed a letter of intent in July to develop a joint interceptor, but a testable prototype is not expected before next year, the paper wrote. Ukraine is also building its own interceptor with European allies under the FREYJA program.

US arms bought with European money

The third is buying American arms with European money through the Prioritized Ukraine Requirements List (PURL), a NATO-run purchasing scheme. US officials have reportedly warned Europe that Trump may halt those supplies if Ukraine keeps striking Russian oil refineries.

Russia is concentrating missiles on a smaller, more specific set of targets, and its jet-powered attack drones are part of the reason, the Institute for the Study of War (ISW) assessed. Its combined attack overnight on 7 October killed 22 people in Pryluky, the State Emergency Service (SES) said as of the morning of 8 October. Russian milbloggers noted the shift the same day.

Russia often uses concentrated drone and missile strikes to overwhelm localized Ukrainian air defenses and destroy urban centers, ISW noted. Pryluky, where the strike killed children, was one of the areas a Russian channel says drew a significant share of the Kh-101s that night. With winter close, ISW expects the same pattern against Ukraine's energy grid, with jet drones partly letting Russia keep its missiles for priority targets without firing many more.

Missile waves on a few areas, Russian channels claim

Russia launched 48 Kh-101, Iskander-K, and Kalibr cruise missiles overnight on 7 October, Ukraine's Air Force reported. It also fired ballistic missiles, Zircon and Oniks anti-ship missiles, and 130 strike and decoy drones, 46 of them jet-powered Shahed-type models.

22 killed in Russian missile strike on Pryluky, including five children

Russian milbloggers claimed the same day that Moscow had grouped a large part of its missile salvo into repeated waves on a few areas, while other weapons kept stretching Ukraine's air defenses elsewhere. The pro-war Russian Telegram channel Dva Mayora described the change as a switch from striking with splayed fingers to a series of hits with missile "fists." Defenders must then absorb a sharply rising load around one chosen site as one wave follows another, the channel claimed.

Citing Ukrainian monitoring channels, it claimed that roughly 30 or more Kh-101 cruise missiles flew toward Pryluky, Kremenchuk, Svitlovodsk, and Oleksandriia in Chernihiv, Poltava, and Kirovohrad oblasts. It put the Kremenchuk group at up to 15 missiles, Kh-101s and Kalibrs among them, aimed at the area of Kremenchuk and its hydroelectric plant.

Jet drones take some of the load off Russia's missiles

ISW said the jet-powered versions penetrate Ukrainian air defenses deeper and more reliably than propeller models. In ISW's assessment, that partly lets Russia concentrate cruise and ballistic missiles on priority targets without significantly raising missile use. Russia builds about 3,000 Geran-4 and Geran-5 jet drones a month, Ukraine's military intelligence agency (HUR) told Militarnyi in August.

Ukraine spent three years learning to catch Russian drones—so Russia made them fly faster

ISW expects Russia to apply the pattern in a likely brutal winter campaign against energy infrastructure. Russia likely intends to make city life untenable and force Ukraine to capitulate to its demands, ISW assessed. Such tactics have not worked before and are unlikely to work now, analysts added.

They called cheap countermeasures to jet drones and small cruise missiles vital, alongside Western air defense aid such as US-made Patriots, which can stop ballistic missiles. Ukraine has already paired a Soviet-era Kub launcher with American RIM-7 interceptors to catch jet drones.

German radar maker Hensoldt has signed a memorandum with Ukraine's Defense Ministry for more large-scale radar deliveries, the company said on 5 October. Ukrainian defense outlet Defense Express reads it as a step toward fitting Hensoldt's TRML-4D, already in Ukrainian service, into FREYJA, a planned shield against ballistic missiles.

Ballistic missiles remain the hardest threat in Russia's air war. After Russia's overnight barrage on 7 October, Ukrainian President Volodymyr Zelenskyy said Ukraine is still searching daily for Patriot missiles. The only other system Ukraine can use against them is the Franco-Italian SAMP/T, which fires Aster 30 interceptors made in small numbers. That gap is why Fire Point is reworking its FP-7 missile into a Patriot-like interceptor. Such an interceptor still needs radars to find its target first.

A memorandum signed during Merz's visit

Hensoldt CEO Oliver Dörre signed the document on the sidelines of German Chancellor Friedrich Merz's visit to Ukraine. Beyond deliveries, it covers further development of radar capabilities. The partners will also study options to deploy and jointly operate TRL-4D LR long-range radars. Hensoldt said this expands cooperation already agreed on in ballistic missile defense.

The TRL-4D LR is the land-based version of a long-range radar Hensoldt also builds for the German Navy, German outlet Sicherheit & Verteidigung reported. The outlet cited Germany's defense procurement office as giving the naval version a range of more than 400 km (250 miles) against air targets. That, it concluded, puts the range well beyond the TRML-4D's.

"The Ukrainian air defence forces urgently need our high-performance radars to help protect infrastructure such as bridges," Dörre said.

Defense Express, describing the same memorandum, tied both the mass deliveries and the joint-operation plan to the TRML-4D. Hensoldt's release names no model for the deliveries and links joint operation to the TRL-4D LR.

Eyes for FREYJA

Hensoldt and Fire Point signed a memorandum on FREYJA at the Eurosatory arms show in Paris in June, with the TRML-4D to play a key role, Hensoldt announced. Fire Point is set to act as prime contractor and hold design authority. Hensoldt is to produce, test, and deliver the radars.

Defense Express expects any study of deployment options to focus on how well the radar detects ballistic missiles and relays that data. Hensoldt has its own unit in Ukraine to work closely with operators, the outlet noted. Earlier, the company began setting up a local hub so Ukraine can service and repair the TRML-4D itself.

Already on duty

Ukraine's military uses the TRML-4D both standalone and as the built-in radar of the IRIS-T SLM medium-range air defense system, Defense Express noted. Hensoldt lists an instrumented range of 250 km (155 miles) at altitudes up to 30 km (19 miles). Defense Express, citing the manufacturer, gives track ranges of more than 120 km (75 miles) for fighter jets and more than 60 km (37 miles) for supersonic missiles.

More radars give earlier warning of ballistic strikes, but they cannot stop them. Until the FP-7.X makes its first ballistic intercept, planned for mid-2027, that job stays with Patriot and SAMP/T missiles. Partners delivered three times fewer air defense missiles in the first half of 2026 than a year earlier, Zelenskyy said on 5 August.
