Eurofighter Typhoon is built upon the strength of four nations – UK, Italy, Germany and Spain. This philosophy and the collective world-leading aerospace and defence technology is realised in the EuroDASS Consortium, led by Leonardo (UK) and comprising Elettronica (Italy), Indra (Spain) and Hensoldt (Germany). This partnership has and continues to design, develop, produce and support the Praetorian Defensive Aids Sub-System for the Eurofighter Typhoon.
