Strategic Note (2026)

The presence of foreign forces in Saudi Arabia remains a cornerstone of the Kingdom's multi-layered defense strategy. While the U.S. continues to provide the primary high-altitude missile defense and tactical air support, European and Greek contributions are specifically tailored toward point-defense and domain awareness. These foreign assets are increasingly integrated into a local logistical framework managed by Saudi Arabian Military Industries (SAMI), which seeks to prioritize the localization of 50% of defense spending under Vision 2030. This includes the localization of maintenance for advanced targeting systems and rotary-wing engines to ensure the readiness of both domestic and joint allied operations.
