The Air Force Life Cycle Management Center formally launched the Eagle Passive Active Warning Survivability System (EPAWSS) Speedline at the Warner Robins Air Logistics Complex in Georgia on May 26, 2026, according to DefenseScoop. The dedicated depot line allows F-15E Strike Eagles to receive the AN/ALQ-250 advanced electronic warfare suite outside their standard Programmed Depot Maintenance cycle — resolving a critical scheduling constraint that had prevented jets from getting the upgrade until their routine depot visit, which for many aircraft was five to seven years away.
Why the Speedline Matters
The standard approach to major aircraft modifications is to bundle them with scheduled depot visits, when the aircraft is already disassembled for maintenance and modification work can be done without taking additional operational time away from the fleet. That model works when the modification timeline aligns with the maintenance cycle, but it becomes a problem when urgency demands faster fielding. For EPAWSS, the Air Force concluded that waiting for normal depot windows would leave too many Strike Eagles without modern electronic warfare protection for too long.
The Speedline resolves that problem by operating as an independent depot line. F-15Es that are not scheduled for Programmed Depot Maintenance for years can be routed to the Speedline specifically for the EPAWSS installation and then returned to operational service. The first aircraft is expected to arrive at the Speedline in June 2026, just weeks after the facility's formal launch.
Lt. Col. Matthew Heil described the system's importance in remarks reported by DefenseScoop, stating that EPAWSS "ensures the F-15E will not just survive, but actively disrupt and dismantle adversary kill chains" in electromagnetically contested environments. That framing reflects the Air Force's broader assessment of electronic warfare as a decisive domain in potential peer-on-peer conflict, where an adversary's integrated air defense system depends on radar and communications links that can be jammed, spoofed, or degraded by an aircraft with capable electronic attack systems.
What EPAWSS Replaces
EPAWSS, designated the AN/ALQ-250, replaces three Cold War-era Tactical Electronic Warfare System components that have been on the F-15E since the aircraft entered service: the AN/ALR-56C Radar Warning Receiver, the AN/ALQ-135 Internal Countermeasures Set, and the AN/ALE-45 Countermeasures Dispenser Set. Each of those legacy systems was designed for a threat environment that no longer reflects the capability of advanced integrated air defense systems operated by near-peer adversaries.
The consolidated EPAWSS system detects, identifies, locates, and responds to air and surface-to-air threats across a significantly wider frequency range than its predecessors, with faster processing that reduces the time between threat detection and countermeasure employment. As reported by The Aviationist, the upgrade also increases chaff and flare decoy capacity by 50 percent — meaningful protection against radar-guided and infrared-guided missiles in a high-threat environment.
A total of 99 F-15E Strike Eagles are slated to receive the retrofit through the Speedline and standard depot pathways. F-15EX Eagle II aircraft, the newer production variant, receive EPAWSS already integrated from the factory — the Speedline addresses exclusively the legacy F-15E fleet that needs the system retrofitted onto an existing airframe.
Program History and Industrial Partners
BAE Systems is the prime manufacturer of the EPAWSS system, with Boeing holding the installation contract valued at approximately $615.8 million. The program entered full-rate production in early 2025. The modification program has been progressing for several years: initial modifications to the first aircraft began in May 2023, and the first two EPAWSS-equipped F-15Es were delivered to the 48th Fighter Wing at RAF Lakenheath in England in January 2025. The 48th Wing, known as the Liberty Wing, operates F-15Es in the European theater and was among the first units to receive the system in an operational configuration.
The Speedline at Warner Robins represents a deliberate acceleration of the installation rate. Without it, the pace of EPAWSS fielding would be constrained by the availability of standard depot maintenance slots, which are scheduled years in advance based on aircraft flight hours and inspection requirements. The dedicated line adds throughput capacity specifically for the electronic warfare modification, decoupling it from the broader depot scheduling queue.
Implications for Electronic Warfare Modernization
The EPAWSS Speedline is part of a broader Air Force push to modernize legacy platforms for electromagnetic spectrum competition. Peer adversaries — particularly China and Russia — have invested heavily in advanced radar systems, electronic attack capabilities, and integrated air defense networks that specifically target the vulnerabilities of legacy U.S. aircraft electronic warfare suites. Bringing the F-15E fleet to a more capable electronic warfare standard reduces that vulnerability without waiting for a new aircraft to replace it.
The approach also carries an industrial policy dimension. Establishing a dedicated modification line at Warner Robins rather than contracting the work to an off-base facility keeps the modification work within the organic government depot system, which has workforce capacity and security infrastructure already in place for classified defense electronics work. It also creates a replicable model for future acceleration programs — if the Air Force needs to rapidly field another modification across a large fleet, the Speedline concept provides a proven template for standing up a dedicated installation capability quickly.
What It Means for Contractors
BAE Systems (Falls Church, Virginia) is the prime manufacturer of the EPAWSS AN/ALQ-250 system. The Speedline's launch expands the fielding rate beyond what standard depot scheduling allows, creating additional throughput demand for BAE Systems' production line. Because 99 aircraft are slated to receive the retrofit and deliveries are now decoupled from routine maintenance cycles, BAE Systems faces a compressed but more predictable delivery schedule — higher near-term volume than a depot-paced plan would have required.
Boeing Defense, Space & Security (Arlington, Virginia) holds the EPAWSS installation contract, valued at approximately $615.8 million, with the program at full-rate production since early 2025. The Speedline creates a dedicated workflow at Warner Robins that keeps Boeing's installation teams continuously occupied rather than absorbing aircraft on an ad hoc basis between scheduled depot inputs. That continuity supports workforce planning and sustains the institutional knowledge that complex electronic system integrations require.
