Israel
Introducing the F-15IA: Israel’s advanced F-15
Israel has long relied on the superiority of the F-15 series for air supremacy. In 2023, the Israeli Air Force made a significant move by ordering 25 F-15EXs, which will carry an F-15IA designation (Israel Advanced). In 2024, Israel increased the order to 50 F-15IAs. Furthermore, plans are in place to upgrade 25 existing F-15Is to the F-15IA standard. This move enhances Israel’s tactical edge, underscores its commitment to maintaining regional air superiority, and strengthens its defense partnership with the United States. An official statement from the U.S. Defense Security Cooperation Agency (USDCA) lauded these developments.
“The United States is committed to the security of Israel, and it is vital to U.S. national interests to assist Israel to develop and maintain a strong and ready self-defense capability. This proposed sale is consistent with those objectives.”- USDSCA

South Korea
Turning South Korea’s Slam Eagles into Eagle IIs
Boeing and South Korea’s Ministry of Defense are finalizing an F-15K modernization plan incorporating elements from the next-gen F-15EX “Eagle II.” Approved in late 2023, this $2.6 billion project will run from 2024 to 2034 to upgrade the Republic of Korea Air Force’s F-15K fleet.
Key upgrades include:
- Replacing the AN/APG-63(V)1 radar with the advanced AN/APG-82 for better detection and multi-target capability.
- Installing BAE Systems’ AN/ALQ-250 EPAWSS for enhanced situational awareness and threat protection.
- Modernizing the cockpit with a Large Area Display for improved visibility.
An analysis by the Korea Institute for Defense Analyses suggested replacing the aircraft’s entire front fuselage rather than just parts, maintaining the rear structure due to its good condition. Post-upgrade, over 50 F-15K Slam Eagles will boast capabilities akin to the F-15EX, ensuring they remain at the cutting edge of military aviation technology.

Saudi Arabia
Can the F-15EX beat out the Rafale and Typhoon?
Saudi Arabia’s interest in the F-15EX marks a continuation of its longstanding relationship with Boeing, dating back to the procurement of 84 F-15SAs (Saudi Advanced) in 2011. During the 2024 World Defense Show in Riyadh, discussions centered on the possible purchase of 54 F-15EXs. Since the Royal Saudi Air Force (RSAF) already operates advanced F-15SAs and upgraded F-15SRs, Boeing emphasizes the F-15EX’s compatibility with Saudi Arabia’s current F-15 fleet, boasting 95% commonality in infrastructure, training, and pilot skills. If the deal is finalized, it will involve upgrading Saudi Arabia’s existing fleet of F-15SAs to match the latest EX standard.
Saudi Arabia is evaluating multiple fighter options for the first time, considering not only the F-15EX but also the Rafale and Typhoon. While the Rafale and Typhoon negotiations are ongoing, the F-15EX stands out for its proven capability in Saudi service, long endurance, and heavy payload, which are crucial for counter-air patrols and intercept missions. Saudi Arabia’s choice between the F-15EX, Typhoon, and Rafale comes amid regional tensions and the ongoing need to modernize its military forces.
