Eagle Passive Active Warning Survivability System (EPAWSS)

BAE Systems’ AN/ALQ-250 Eagle Passive Active Warning Survivability System (EPAWSS) protects U.S. Air Force F-15s with digital electronic warfare technology to maximize mission effectiveness and survivability in highly contested environments.

Fighter aviation

The cutting edge. Eagle EPAWSS

Advanced EW capabilities and extended lifecycles

The advanced all-digital Eagle Passive Active Warning Survivability System (EPAWSS) provides the F-15 with fully-integrated radar warning, geolocation, situational awareness, and self-protection solutions to detect and defeat surface and airborne legacy, current, and future threats in highly contested, dense signal environments. EPAWSS is equipped with advanced radio frequency (RF) electronic countermeasures (ECM), enabling deeper penetration against modern integrated air defense systems and providing rapid response capabilities designed to protect the aircrew.

The all-digital EPAWSS is notably smaller and lighter than previous EW systems for the F-15. EPAWSS is provisioned for new capabilities and future upgradability. EPAWSS improves reliability and maintainability, as well as drastically extending service life. These benefits reduce lifecycle costs, keeping the Eagle relevant now and in the future.

How it works

BAE Systems’ advanced EPAWSS technology provides pilots with maximum situational awareness, helping them detect, identify, and rapidly respond to potential threats by collecting and processing electromagnetic energy, instantaneously creating a comprehensive, 360-degree picture of the battlespace. EPAWSS has broad instantaneous bandwidth and a high-speed scan capability to detect all RF threat classes, including low probability of intercept and modern agile threats. To defeat threats, its ECM toolbox leverages many years of proven countermeasures techniques and can be programmed to defeat both current and future threats.
