Briefing

What Hype is tracking

The EPAWSS deal directly advances South Korea’s F-15K survivability upgrade, adding 360-degree threat warning and electronic countermeasures for 59 jets under the ALQ-250 modernization path.
Scale and timeline matter: the upgrade program runs through 2037 (roughly $3.1 billion), shaping sustainment, obsolescence management, and combat-ready force planning for the Slam Eagle fleet.
For suppliers and primes, the contract reinforces BAE Systems’ role in next-generation fighter self-protection—an area increasingly tied to air-defense proliferation and threat-sensing requirements.
