German company Hensoldt to supply TRML-4D radars to Latvia and Slovenia.

On July 4, 2024, the German company Hensoldt secured contracts to support the air defense capabilities of Latvia and Slovenia under the German-led 'European Sky Shield Initiative' (ESSI). As part of an order from Diehl Defence worth over 100 million euros, Hensoldt will supply its TRML-4D radars, including maintenance and training packages, to these two countries. These radars will be deployed as part of the IRIS-T SLM air defense system.

Hensoldt CEO Oliver Dörre highlighted the substantial demand for enhanced air defense systems in Europe and noted the company's progress in expanding production capacity to meet this demand, as Hensoldt now has over 80 air defense radars under contract within the ESSI initiative. The TRML-4D radar has demonstrated effective detection capabilities in Ukraine and performed well during live tests in Latvia. Utilizing AESA (Active Electronically Scanned Array) radar technology, the TRML-4D can detect and track up to 1,500 targets within a 250-kilometer radius. It is designed to identify various air targets, including cruise missiles, rockets, drones, and aircraft.

Hensoldt has extensive experience with radar systems for air defense and continues to develop technologies in this field. Its portfolio includes the Spexer short-range radar, the Twinvis passive radar, and radars for securing ship and air traffic. Both the TRML-4D and the Spexer radars are part of the German Armed Forces' NNbS air defense system for close and short-range protection, initiated in January. Additionally, Hensoldt supplies radars for the German Navy’s new frigates and corvettes, airspace surveillance, and approach control at military airfields.

The TRML-4D, part of Hensoldt's C-band (NATO G-band) radar family, is designed for remote-controlled, ground-based air defense. It is a software-defined sensor system, allowing for future operational flexibility. Its features include high accuracy in the C-band, robust track ranges, and an AESA look-back feature for rapid track initiation and robust weapon support. The system can be deployed and redeployed within 10 minutes, offering survivability in congested combat environments, especially when used with Hensoldt's Twinvis Passive Radar. It also includes dedicated ECCM features and integrated Identification Friend or Foe (IFF) systems.

Technically, the TRML-4D radar operates in the C-band (IEEE designation) and G-band (NATO), using Pulse Doppler and GaN Solid State AESA technologies. It has a range of up to 250 kilometers, a height detection capability of 40 kilometers, and can track targets with radar cross sections as small as 0.01 square meters. The minimum range is less than 200 meters, with elevation coverage from -2° to 70°, extendable to -10° electronically. It supports 3D tracking for over 1,500 targets, with confirmed track ranges of over 120 kilometers for fighter aircraft and over 60 kilometers for supersonic missiles. The radar’s track accuracy includes less than 0.2° in azimuth, less than 0.3° in elevation, and less than 15 meters in range. Scanning capabilities include mechanical azimuth scanning with 360° continuous rotation and electronic elevation scanning with AESA stacked beam and electronic stabilization. Operational functions encompass target categorization, cued search and tracking, own weapon tracking, kill indication, and overflight tracking.
