Briefing

What Hype is tracking

The EPAWSS award covers survival-focused electronic warfare for 59 ROKAF F-15K jets, directly shaping how Seoul modernizes its air-delivered threat response against modern air defenses.
The timeline—up to 2037, with first F-15K+ jets targeted for late 2028—provides a measurable schedule for capability fielding and sustainment planning.
The contracting chain (BAE’s procurement tied to Boeing’s F-15K upgrade work) is a useful signal for how prime-OEM and EW integrator roles are being structured in South Korea’s fast-evolving fighter modernization program.
