Saudi Arabia weighing F-15SA upgrades to F-15EX standard as Boeing pitches retrofit and new-build EX options

Saudi Arabia is weighing upgrades to its large F-15SA fleet to bring aircraft to the F-15EX standard, and Boeing is actively proposing both retrofit packages and new-build EX options. Company officials say there is strong potential for a broad upgrade programme or an EX purchase.

Briefing

What Hype is tracking

Upgrading F-15SA to F-15EX would follow a growing trend of modernising legacy fleets and create significant sustainment, integration and industrial-workshare opportunities; the USAF recently awarded Boeing up to $2.8B to modernize South Korea’s F-15K toward EX standard (see precedent) (source:d748fffb-b667-4996-977e-bf77c96ebb6d)
A Saudi decision to pursue wide-scale EX upgrades or purchases would deepen U.S.–Saudi defence ties and intersect with other U.S. efforts to localize advanced capabilities and sustainment in the kingdom (see related shift toward in‑country software and sustainment activity) (source:cc86d5a1-6e6e-4161-bb3a-76d09dedba14)
Any major fighter upgrade or purchase will have regional force‑balance implications and sits alongside ongoing debate over U.S. fighter sales to Saudi Arabia, which has drawn close scrutiny in prior assessments (source:f12247c0-df25-46bd-9fbe-98c475556d0d)
