The AN/ALQ-135 is a fully automatic, dual mode electronic combat system that manages and defeats multiple threats simultaneously, prioritizing and neutralizing the most imminent dangers. The Band 3 System provides high-band coverage; with the addition of Band 1.5, the ALQ-135 provides full spectrum threat protection. The systems simultaneously defeats multiple simultaneous pulse, pulse Doppler and continuous wave threats.
Designated "mission essential" for every F-15 going into combat, the ALQ-135 logged more than 6,600 hours of combat during Operation Desert Storm without losing a single aircraft to a covered threat. During the lifetime of the ALQ-135 system, Northrop Grumman has continually provided upgrades in order to meet the ever-evolving threat.
