German company Hensoldt AG says it has received an order worth € 340 million to supply Ukraine’s air defense forces with TRML-4D and SPEXER 2000 3D MkIII radar systems. These radar systems have already been in use in Ukraine since the beginning of the Russian invasion.

“Our high-performance radars are urgently needed by Ukrainian air defence,” says Hensoldt CEO Oliver Dörre, emphasizing that the company is proud to supply systems that are “critically important for protecting civilians.”

What is TRML-4D?

TRML-4D radars are based on advanced Active Electronically Scanned Array technology. They can simultaneously detect and track up to 1,500 targets within a radius of up to 250 km, including drones, aircraft, helicopters, and cruise missiles.

Their fast response time and ability to operate under complex conditions make TRML-4D systems essential in providing precise countermeasures against Russian aerial attacks.

SPEXER 2000 is the “eyes” of Skyranger guns

SPEXER 2000 3D MkIII systems are designed for the automatic detection and classification of ground, maritime, and low-flying aerial targets. They are integrated into the Rheinmetall Skyranger 30 air defense gun system, which provides close-range and very short-range protection.

The system is based on the wheeled armored Boxer vehicle, equipped with a combat module featuring a 30mm Swiss Oerlikon KCA gun firing 1,200 rounds per minute. Optionally, it can be fitted with a launcher for two FIM-92 Stinger or Mistral missiles, according to Militarnyi. 

The gun’s ammunition includes a wide range of shells, including airburst rounds with radio fuses. The total ammunition load consists of 252 30mm shells. The vehicle is equipped with five antennas, providing full 360-degree coverage.

It also features the Rheinmetall FIRST passive target acquisition system, which excels at detecting small targets. Since it emits no radar signal, the system can operate without being detected by enemy electronic intelligence.

The system is a part of Germany’s NNbS program, a new short-range air defense “umbrella” for the Bundeswehr, meaning Ukraine is receiving the best from NATO’s arsenal.

German defence contractor HENSOLDT has secured a contract worth over 340 million euros ($399 mn) to supply radar systems for Ukraine’s air defence capabilities, the company reported on 24 July.

The order includes TRML-4D high-performance radars and SPEXER 2000 3D MkIII short-range radars as part of the Near and Very Short Range Air Defence System commissioned by the German Armed Forces.

“Our high-performance radars are urgently needed by Ukrainian air defence,” HENSOLDT CEO Oliver Dörre said. “A number of radars have been protecting Ukraine since the start of Russia’s war of aggression. We are proud to be supplying further systems. The radars are extremely important for protecting citizens.”

Ukraine first received the TRML-4D radar in October 2022, with an initial delivery of four units integrated into their IRIS-T air defense systems. Additional deliveries followed, including another four TRML-4D radars in June 2023, and six more units are scheduled to be delivered by the end of 2024 as part of a major contract with HENSOLDT. 

The TRML-4D radar operates on AESA (Active Electronically Scanned Array) technology and can detect and track approximately 1,500 targets within a 250-kilometre radius. The system identifies and classifies cruise missiles, drones, aircraft and helicopters.

SPEXER radars provide surveillance across various ranges for automatic detection and classification of ground, sea and low-flying air targets. The SPEXER 2000 forms part of Rheinmetall’s Skyranger 30 cannon-based air defence system and is deployed in German artillery installations and qualified air defence systems.

According to HENSOLDT, several of their radar systems have been operational in Ukraine since the beginning of the war. The company maintains decades of experience in air defence radar systems and continues developing technologies in this sector.

The radar delivery represents part of Germany’s broader military support package for Ukraine’s defence against Russian forces.
