What is Praetorian DASS? The Eurofighter’s Integrated Electronic Defence System
Modern air combat is won as much in the electromagnetic spectrum as in the physical sky. The Praetorian DASS (Defensive Aids Sub-System) is the Eurofighter Typhoon’s integrated electronic self-protection system — combining radar warning, laser warning, missile approach warning, active jamming, and chaff/flare dispensing in a single architecture.
