Based on multi-channel AESA technology and a high-performance processor, the ECRS Mk1 will significantly enhance the capabilities of the Eurofighter, which Airbus manufactures for the German and Spanish air forces. The ECRS Mk1 architecture is designed to enhance the fighter's full range of missions, including advanced air-to-air and high-resolution air-to-ground capabilities, as well as both passive and active electronic warfare. The contract was signed in 2020.
In April 2024, the German and Spanish military customers decided to introduce advanced subsystems for the Processor and APSC into the ECRS Mk1 Step 1.

“In less than 13 months, we have completed production of the first radars with this new hardware, and a comprehensive evaluation phase is already well underway. The new APSC and Processor provide the Mk1 with a significant performance improvement, including ultra-fast mode switching, real-time mission flexibility, and future autonomous, task-based operations with AI support,” explains Dr. William Gautier, Technical Director at HENSOLDT. “This new hardware is integrated with completely redesigned software that allows us to fully exploit the multi-channel AESA technology. Furthermore, thanks to its modern architecture and design, the ECRS Mk1 is sustainable for customers in the long term.”

Borja Miño, technical director of Indra's Eurofighter Program, stated: “The new processor architecture also brings significant improvements, including increased computational performance, enhanced parallel processing capabilities, and support for advanced signal processing algorithms. These improvements not only boost current performance but also provide the necessary headroom for future software upgrades and sensor fusion capabilities.”

The first radar prototypes will be used for extensive qualification and flight testing. The Mk1 Step 1 will demonstrate its performance during test flights aboard Germany's ATRA air testbed.

Following evaluations and tests carried out during the first half of 2025, HENSOLDT and Indra plan to begin serial production of the Mk1 Step 1 in the summer of 2025. The ECRS Mk1 will be integrated into Eurofighter Quadriga aircraft at Airbus Defence and Space in Manching, Germany.

The Mk1 Step 1 will provide a robust air-to-air capability to the air forces of Germany and Spain. Future software upgrades will transform the Mk1 radar into a fully multirole radar, including air-to-ground and electronic warfare roles. These upgrades will also enable task-based operations to reduce pilot workload and improve system performance.
