Passive radar aims a Skynex battery

Rheinmetall reported on 19 August that HENSOLDT's emitter-free Twinvis radar had cued a Skynex gun battery through its Skymaster command system at a German Air Force exercise.

Key takeaway

German air defence cued a gun battery from a radar that never transmitted.

Rheinmetall reported on 19 August that HENSOLDT's Twinvis, a radar that locates aircraft by reading reflections of existing broadcast signals rather than transmitting its own, had been fused into Rheinmetall's Skymaster command system and used to drive a Skynex gun battery at the German Air Force exercise Timber Express 2026 1. Link 16, NATO's tactical data link, carried the common air picture between them.

Passive radar sits silent while a conventional fire-control set advertises the battery's location the moment it sweeps, and that silence is the advantage Rheinmetall is buying. Against cheap attack drones the transmitting side loses that trade badly, because a battery which gives itself away invites the next salvo. Twinvis finds the target without revealing the gun, so the Skynex position stays unknown until it fires. The integration work, rather than either box on its own, is what produces that: two manufacturers' equipment speaking through one command layer over a standard link.

Britain and Turkey signed the second agreement of the fortnight. BAE Systems, which unveiled Brontanax, Britain's first sovereign combat drone, in July , and the Turkish radio-frequency specialist TUALCOM signed a memorandum of understanding on 12 August to assess resilient communications, assured navigation and electronic warfare for future autonomous platforms serving UK, Turkish and export customers 2. The work addresses the part of such an aircraft that fails first under contest. No money and no programme attach to the memorandum. What does attach is a shared judgement about where autonomous systems break under contest, and it is not the airframe.

Deep Analysis

In plain English

Rheinmetall and HENSOLDT, two German defence firms, connected a passive radar system (one that listens for reflections off existing radio signals instead of sending out its own, making it harder to detect) into the software that aims an anti-drone gun battery, tested at a German air force exercise. Separately, British firm BAE Systems and Turkish firm TUALCOM agreed to study working together on secure communications and jamming-resistant technology for future drones. Neither event is a finished weapons system yet; both are steps toward one.

Deep Analysis
Root Causes

Passive radar such as Twinvis detects drones by their reflection of existing radio and TV signals rather than emitting its own radar pulse, which makes it harder for an adversary to detect and jam; fusing it into Skymaster lets Rheinmetall's Skynex guns engage targets a conventional active radar might reveal itself trying to find.

The BAE-TUALCOM memorandum is a separate, earlier step: an agreement to assess technology, not a contract to build it, reflecting how far UK-Turkish autonomous-systems cooperation still has to travel before it produces fielded equipment.

What could happen next?
  • Meaning

    Fusing passive-radar sensing into a live gun-battery command system moves counter-drone defence toward harder-to-detect sensors, a response to jamming and radar-homing threats.

DAPA folded drone and roadside-bomb jammers into an 18-year, KRW 3.448 trillion K2 tank upgrade approved 11 August, rather than fund counter-drone kit as its own programme. Seoul is treating the threat as permanent enough to write into a platform's lifecycle, not urgent enough to buy ahead of it.

NSPA named five pre-qualified counter-drone suppliers under new framework contracts on 27 July, giving allies a purchasing route with no published budget attached. A framework without committed money is an instrument waiting for a spending decision, not a guarantee one is coming.

Ukraine's forces strike with more than 70 AI and computer-vision systems drawn from over 200 domestic producers, the ministry said on 18 August, a supplier base neither Washington's tariff fight nor Beijing's export licence touches. Kyiv is scaling capability faster than either government is writing rules for it.

A European manufacturer selling components into the United States faces the same 100 per cent tariff and 3 September deadline as any other foreign supplier, with the duty-free onshoring carve-out available only to firms building on American soil. That leaves it to absorb the cost, relocate assembly, or cede the US market rather than shop around a rival supply chain.

Exporters now need a case-by-case licence for each US-bound dual-use shipment after MOFCOM's 5 August order, with no published review clock. The same week Shenzhen logged nearly 200,000 domestic logistics-drone sorties and Hunan reported record spraying coverage, a home market large enough to absorb what the licence regime slows from leaving the country.
