Given the multitude of threats and conflicts in constant evolution, building a reliable, accurate, up-to-date Recognized Air Picture (RAP) is becoming a challenge. To maintain airspace sovereignty, Forces need to rely on assets that provide superior situational awareness at all times.
The resurgence in geostrategic confrontations has significantly increased demand for airspace protection solutions. In addition to conventional aircraft and missiles, unmanned air vehicles (UAVs) now also constitute a threat to airspace sovereignty. Easy-to-deploy Ground Master (GM) radars have become highly survivable assets for detecting all kinds of threats at long range and at low altitude.
Leveraging on years of successful field experience, GaN technology and a digital architecture, the new GM400 Alpha provides 5 times more processing power, an increase in instrumented range of 10% (515km) and is ready for advanced artificial intelligence capabilities.
Estonia is historically a long-standing user of the GM400 radar since its first acquisition of 2 GM400 in 2009 for MRR2010 and mid-life upgrades in 2022. This new contract demonstrates the Estonian Center for Defence Investments (ECDI) satisfaction with Thales radar solutions. In particular, the mobility of GM400 Alpha, rather unique for a radar of this class, is well tuned for operational survivability.
Designed to offer unprecedented mobility, GM400 Alpha fits into a compact 20ft container with built-in lifting systems, and offer excellent redeployment times.
Today more than 200 Ground Master radars have been sold around the world, proof that this radar family is widely recognized for its high reliability and unparalleled performance.
“We highly value the long-term collaboration with Thales,” said Priit Soosaar, Strategic Category Manager (C4I, Cyber & Radars) at the Estonian Centre for Defence Investments. „In the current market situation, we found this to be an economically advantageous solution with timely deliveries, ensuring a high-quality air picture on NATO’s eastern flank.”
“The latest contract strengthens Thales position as defense technology provider in the Baltic region and doubles the number of GM400 radars installed in Estonia. We are very proud to provide both civil air traffic safety solutions as well as surveillance radars for the Estonian Air Force. This is another milestone in developing a long-term defence partnership with Estonia and neighboring countries” Magdalena Nizik, CEO Thales Poland & Baltic Countries.
Note to editors
Ground Master 400 was the first radar of the Ground Master product family, The Ground Master family deploys the same architecture and building blocks leveraging synergies in terms of innovation and support. Today more than 200 Ground Master radars are sold around the world.
