Beyond Stealth: How EPAWSS Is Rebuilding the F-15K for the Electromagnetic Battlespace

Inside South Korea’s Shift Toward a Software-Defined Survivability Architecture for Long-Range Strike

The F-15K is not becoming a stealth fighter.

It is being redesigned to survive without becoming one.

South Korea’s F-15K modernization is often described as a radar and electronic warfare upgrade. But the deeper transformation lies in how AESA radar, mission computers, electronic warfare, threat warning, and networked targeting are being brought together into a new survivability architecture.

This DKI Defense Analysis Brief examines what the transition from 2024 FMS approval to actual component contracting means for the future combat role of the ROK Air Force’s F-15K fleet.

The central question is not simply whether EPAWSS improves the aircraft.

It is whether a non-stealth, heavy long-range strike platform can remain combat-relevant in an increasingly lethal electromagnetic and integrated air-defense environment—and what technical, operational, and sustainment conditions must be met for that transformation to succeed.

For officers, NCOs, military academy cadets, graduate students, defense researchers, and professionals studying airpower modernization, electronic warfare, force integration, and future strike architecture.

The future of the F-15K will not be decided by payload and range alone.

It will be decided by how well it can see the threat, understand the threat, survive the threat—and remain ready to fight.
