EPAWSS offers full-spectrum EW capabilities, together with radar warning, geolocation, situational consciousness and self-protection, to the F-15E Strike Eagle and F-15EX Eagle II.

The U.S. Air Pressure not too long ago accomplished the Preliminary Operational Take a look at & Analysis (IOT&E) of the Eagle Passive Lively Warning Survivability System (EPAWSS) for the F-15E Strike Eagle and F-15EX Eagle II. The AN/ALQ-250 EPAWSS, put in from the manufacturing facility on the F-15EX and at the moment being retrofitted on various F-15Es, offers full-spectrum EW capabilities, together with radar warning, geolocation, situational consciousness, and self-protection to the F-15.

EPAWSS is absolutely built-in with radar warning, geo-location and elevated chaff and flare functionality to detect and defeat floor and airborne threats in signal-dense and highly contested environments. Due to this, the system allows freedom of maneuver and deeper penetration into battlespaces protected by trendy built-in air protection programs.

“EPAWSS is a leap in know-how, bettering the lethality and fight capabilities of the F-15E and F-15EX in contested, degraded environments in opposition to superior threats,” mentioned Maj Bryant “Jager” Baum, EPAWSS Take a look at Director for the Air Pressure Operational Take a look at & Analysis Middle (AFOTEC). “EPAWSS has set the baseline for EW inside the fighter group.”

BAE Programs, the manufacturer of the system, notes EPAWSS is notably smaller and lighter than earlier EW programs for the F-15. “EPAWSS was designed for upgradeability and speedy functionality insertion,” added Amy Nesbitt, EPAWSS program supervisor at BAE Programs. “We’re utilizing agile software program growth to offer iterative upgrades to fielded EW programs—permitting our prospects to defeat future electromagnetic threats.”

EPAWSS is absolutely built-in with radar warning, geo-location and elevated chaff and flare functionality to detects and defeat floor and airborne threats in signal-dense and extremely contested environments, in line with BAE Programs. The system is at the moment not built-in with the AN/AAR-57A(V) Widespread Missile Warning System (CMWS) designed to detect infrared threats, even when the F-15EX features the same mounting points used for these sensors on the F-15QA and F-15SA.

Chaff and flares capability has been increased by 50%, with 4 extra dispensers added within the EPAWSS fairings behind the tail fins (two for every fairing), for a complete of 12 dispenser housing 360 cartridges. This enchancment is essential as in trendy situations chaff and flares are sometimes launched preemptively to counter MANPADS (Man Transportable Air Protection System), which means that now the Eagle can have extra countermeasures accessible for a greater safety.

EPAWSS additionally integrates cognitive digital warfare to raised discriminate the alerts obtained by the system. This functionality was demonstrated throughout the Northern Edge 2023 large force exercise test event, which examined EPAWSS’ potential to quickly reply to beforehand unencountered electromagnetic threats. The assessments challenged the system’s potential to course of in-mission sensor knowledge, create beautiful methods, and optimize waveforms in actual time.

“Our shut collaboration with the U.S. Air Pressure permits us to mature EPAWSS cognitive processing capabilities,” mentioned Chip Mosle, program director at BAE Programs. “By incrementally testing and fielding cognitive EW options to confirmed programs equivalent to EPAWSS, we’re enabling tactical spectrum overmatch in opposition to superior threats which might be unpredictable, evolving, and adaptable.”

Within the newest Director, Operational Take a look at & Analysis report, it’s talked about that EPAWSS replaces three functionally out of date F-15 legacy Tactical Digital Warfare System parts: the AN/ALR-56C Radar Warning Receiver, the AN/ALQ-135 Inner Countermeasures Set, and the AN/ALE-45 Countermeasures Dispenser Set. The system additionally integrates with the F-15 AN/APG-82(V)1 radar and Superior Show Core Processor II mission laptop.

The primary modifications for the F-15E, particularly an plane from the 48th Fighter Wing primarily based at RAF Lakenheath, UK, started in Could 2023 and the plane is predicted to return to its unit by 2QFY24. In whole, the Air Pressure plans to retrofit 99 F-15Es and equip all F-15EXs with EPAWSS.
