Praetorian Defensive Aids Suite background information
http://www.selex-sas.com/EN/Common/file ... torian.pdf
Praetorian is an integral part of the Eurofighter Typhoon’s fighting equipment, providing
comprehensive protection and an important contribution to the platform’s situational
awareness capability. Created specifically for use aboard the four-nation Eurofighter
Typhoon multirole combat aircraft, the Praetorian Electonic Warfare (EW) suite is designed
to provide its host platform with protection against air-to-air and surface-to-air threats. 360°
cover is provided, with the system carrying out threat detection and evaluation before
automatically activating a countermeasure response.
SELEX Galileo leads the EuroDASS consortium which is responsible for the design,
development and supply of Praetorian as the Typhoon’s combat effective defensive aids
suite. The consortium also includes Elettronica of Italy, INDRA of Spain and EADS of
Germany.
A Proven Product
Praetorian is fitted internally to the Typhoon aircraft, providing spherical threat warning and
protection against air to air and surface to air threats without the need to carry flight profilelimiting pods. Enhanced survivability is achieved through a comprehensive set of self
defence sensors and countermeasures which detect and evaluate potential threats at
maximum range and automatically deploy the most effective countermeasures.
The Electronic Support Measures (ESM) and Laser Warner together with the active Missile
Approach Warner (MAW) work together with the Eurofighter Typhoon’s on board sensing
systems to give timely warning and identification of threats to the user.
The Electronic Countermeasures System (ECM) works automatically by activating the most
suitable on or off board counter to the threat while the information is displayed graphically on
the cockpit multi function displays. This allows the pilot a further option of manoeuvre or
manual override.
The ECM incorporates Digital Radio Frequency Memory (DRFM) technology and provides a
comprehensive range coherent and non coherent jamming techniques.
Praetorian features innovative active off board countermeasures, a system which includes
two Towed Decoys and provides a unique ability for decoys to be deployed and operate over
any part of the platform’s flight envelope, including manoeuvres under full power and high ‘g’.
Passive countermeasures include a range of ‘Chaff’ and ‘Flare’ payloads.
Praetorian’s system Mission Dependent Data is fully user programmable to ensure complete
national control of the Electronic Warfare (EW) software library content.
The system is designed to support future growth modification thus ensuring protection for
Eurofighter through the 21st Century.
