Hensoldt recently received a major order to supply radars to strengthen Ukraine’s air defense. As part of a comprehensive order package worth more than 340 million euros, TRML-4D high-performance radars and SPEXER 2000 3D MkIII shortrange radars will be delivered.

The TRML-4D is based on the latest Active Electronically Scanned Array (AESA) radar technology. It ensures the rapid detection and tracking of around 1,500 targets within a radius of up to 250 km. It is capable of quickly and reliably detecting, tracking and classifying all types of air targets – cruise missiles, drones, aircraft and helicopters.

The SPEXER radar family offers surveillance radars for various ranges for the automatic detection and classification of ground, sea and low-flying air targets. The SPEXER 2000 is part of the new Skyranger 30 cannon-based air defense vehicle from Rheinmetall. It is also used in the German c-UAS Feldlager (ASUL), qualified air defense, and high-energy laser for drone defense (HoWiSM).

Hensoldt has decades of experience with radar systems for air defense and is actively driving forward the further development of key technologies in this field. In addition to the TRML-4D and SPEXER, the company’s portfolio includes the Twinvis passive radar and radars for securing ship and air traffic. Both the TRML-4D and the SPEXER are part of the ‘Near and Very Short Range Air Defense System’ (NNbS) ordered by the German Armed Forces.
