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.

A Ukrainian defense company has shown a new way to knock FPV drones out of the sky, unveiling a net-firing interceptor at the IT Arena tech conference in Lviv, dev.ua reported. The system, called Mangal and developed by Phantom Defense, is still a prototype—the company says the first production units could reach the market in a few months.

Ukraine's counter-drone work has turned into a crowded contest, with firms racing to field jammers, interceptor drones, and net-throwers that can blunt Russia's growing use of cheap FPVs.

What Mangal does

Phantom Defense designed the modular launcher to defend positions, vehicles, and other targets against enemy drones. It fires a special net weighted with sinkers. The net opens the moment it fires, tangling the drone and dragging it down. One module holds six charges. Two cameras give the crew a clearer view, and the system can detect targets on its own, which speeds up how fast an operator spots a threat. Crews can fix Mangal in place to guard checkpoints, trenches, or infrastructure, or bolt it onto a vehicle.

Why a net

FPV drones—aircraft a pilot flies straight into a target—have become a routine danger along the front. A small, fast drone is hard to hit with a single round. A net spreads as it travels, so it is more forgiving to aim. Neither Phantom Defense nor the outlets covering the launch have said how far Mangal's net can reach.

Other net-based counters

Other developers are turning to nets too. The WINFLY Spider is an interceptor drone that snares a target in a net and returns to its launch point intact, at about $27 a shot. That lets one aircraft make repeated intercepts instead of being spent on a single kill. Scan Horizon comes from Postup Solutions, a firm registered in Wrocław, Poland, and pairs a net launcher from Ukrainian company Ptashka Drones. Its net reaches about 30 meters. Contra Drone, meanwhile, has shown interceptor missiles that can reportedly carry net warheads alongside other options.
