CROWN - European active electronically scanned array with Combined Radar, cOmmunications, and electronic Warfare fuNctions for military applications

CROWN project will address research and technological development activities to go a step further in the development of European next-generation multifunction radiofrequency (RF) system mainly for airborne surveillance platforms based on Active Electronically Scanned Arrays (AESA) technology capable of integrating radar, electronic defence and communications functions into a single compact and lightweight item of equipment. The project makes a significant contribution towards building European industrial defence capability and ensuring industrial independence.

CROWN is a Research Action targeting for TRL 4 that mostly focuses on the proposed technology (system and separate components) development until possible testing in the laboratory environment. Work and results obtained during CROWN will help to show the way forward giving an idea of the investment, milestones and research activities needed to develop a prototype (TRL7) by 2027 reinforcing European technologies. 

CROWN activities include R&D assessment and recommendations on critical technologies key for the development of future European multifunction RF AESA systems establishing roadmaps and priorities for EU suppliers. Project’s R&T activities on system and component level will be based on the requirements identified from the main stakeholders and on the architecture study fulfilled. In addition, a small-scale prototype will be also designed, manufactured, and tested in a laboratory environment.
