29th April 2021 – Leonardo, on behalf of the EuroDASS Consortium, has signed a contract to supply the Praetorian
Defensive Aids Sub‐System (DASS) for the new Eurofighter Typhoon aircraft being supplied under the German
Quadriga programme. This will see 38 of the latest standard Eurofighter Typhoon aircraft delivered to the German
Luftwaffe to replace their Tranche 1 Typhoon aircraft.
The Typhoon’s Praetorian DASS equips the aircraft with advanced protection from threats including Infra‐Red (IR or
heat‐seeking) and radar‐guided missiles. The system is well‐regarded by users and has been battle‐tested on peacekeeping
operations in Libya and Syria. It integrates sensors and electronic warfare jamming to provide exceptional
situational awareness, platform protection and advanced electronic deception techniques.
Critically, Praetorian is an open and programmable electronic warfare system. This means that Germany is in complete
control of its mission data and can boost the survivability of its Typhoons by fine‐tuning the system to the actual
situation on the battlefield on a mission‐by‐mission basis. Mission data can be fed into the Praetorian system in an
extremely short time, often just hours. In comparison, some other aircraft are equipped with defensive aids systems
that include a generic mission data set and that feedback loop can take several months.
Quadriga is a vote of confidence in the Eurofighter Typhoon that says that the platform will be the backbone of the
Luftwaffe out to the 2060s. This sends a strong message to potential future partners, in the near term Finland and
Switzerland, who will be able to rely on long‐term commitment to Typhoon. Further opportunities for Typhoon and
Praetorian include additional orders from Spain and Germany as well as future export orders.
Looking towards the future, EuroDASS are keen to support technology de‐risk for the next generation of fighters.
Praetorian presents a stable platform to spiral develop future technology, which will not only provide future capability
gain for Typhoon, but also provide valuable knowledge and technology transfer into the next generation of future
combat air systems.
Through the Eurofighter Long Term Evolution (LTE) study, EuroDASS are working with the Eurofighter Partner
Companies and Nations to consider national requirements and how they can be delivered in an agile, cost effective
manner, providing capability longevity to the Typhoon’s out of service date, whilst remaining supportive to future air
combat development work.
