U.S. Secretary of State Marco Rubio is scheduled to visit Athens on Wednesday, October 6, 2026, with defense matters taking center stage in discussions. The primary focus will be on weapons systems procurement for Greece's current and future fighter fleet. Talks are expected to address armament options for the 20 F-35 fighter jets planned for delivery beginning in 2028, as well as for existing F-16V (Viper) aircraft and F-16 Block 50 platforms slated for Viper configuration upgrades.

Among the weapon systems attracting Greek interest is the AGM-158B JASSM-ER cruise missile. However, sources indicate uncertainty surrounding the procurement timeline for this system. The JASSM-ER delivery schedule is notably lengthy, with U.S. domestic demand and inventory constraints potentially extending delivery timelines to 48 months. Despite media reports, no final procurement decision has been made regarding the missile. Sources note that while the topic is likely to be raised in bilateral discussions, this does not necessarily indicate an imminent sale.

The Hellenic Air Force is also demonstrating strong interest in the AIM-120D, the latest variant of the AMRAAM missile family. Currently, both Greece and Turkey operate various versions of the AIM-120C family. Looking further ahead, Greek air force officials are closely monitoring developments around the AIM-260 JATM, a next-generation air-to-air missile intended to gradually replace the AIM-120 AMRAAM. This program is regarded as one of the most advanced options for future air combat. However, near-term U.S. approval for this sale appears unlikely, as the project has been developed with much of its technical and operational characteristics classified.

The scope of Greco-American defense cooperation is reflected in financial figures. According to U.S. State Department data, Greece maintains 11.29 billion dollars in active Foreign Military Sales (FMS) agreements. Major programs include the upgrade of 84 F-16s to Viper configuration, the acquisition of 7 MH-60R Seahawk helicopters, and the modernization program for 11 S-70B Aegean Hawk helicopters. This comprehensive procurement framework aims to strengthen Greece's air defense capabilities to NATO standards.

From a Turkish defense industry perspective, Greece's missile procurement efforts represent a development with potential regional implications. The acquisition of long-range cruise missiles such as JASSM-ER could influence military balance in the Aegean Sea. Turkey's own missile programs—including ATMACA, SOM, BORA, and HİSAR systems—continue to monitor regional developments closely. As a NATO ally, Greece's weapons acquisitions indirectly influence Turkey's defense strategy and procurement decisions, shaping the broader security dynamics of the Eastern Mediterranean.
