Iniochos 2025: Strengthening Multinational Air Power and Strategic Alliances

Iniochos 2025, the Hellenic Air Force’s (HAF) premier multinational air exercise, unfolded from March 24 to April 13, 2025, at Andravida Air Base in the northwest Peloponnese. This year’s iteration marked the most extensive participation in the exercise’s history, underscoring its growing significance in fostering interoperability and strategic cooperation among allied and partner nations.

Exercise Overview and Objectives

Originating in the late 1980s as a national tactical-level exercise, Iniochos has evolved into a comprehensive training event that simulates complex air warfare scenarios. The 2025 exercise was structured into three phases: deployment of participating forces (March 24–30), execution of operations (March 31–April 11), and redeployment (April 11–13). A notable feature was the “Spotters Day” on April 7, allowing aviation enthusiasts to observe the operations firsthand.

The exercise aimed to provide realistic training by creating a dynamic battle environment. Missions covered a broad spectrum of air operations, including Offensive and Defensive Counter Air Operations (OCA/DCA), Strategic Air Operations, Air Power Contribution to Counter-Land and Maritime Operations (APCLO/APCMO), Reconnaissance Missions (RECCE), Combat Search and Rescue (CSAR), Time-Sensitive Targeting (TST), and protection of High-Value Airborne Assets (HVAA).

Participating Nations and Assets

Iniochos 2025 saw participation from a diverse array of countries, reflecting a commitment to collective security and operational readiness. The participating nations and their contributions included:

France: Mirage 2000 aircraft
India: Su-30 fighters
Israel: Gulfstream G550 surveillance aircraft
Italy: Tornado aircraft
Montenegro: Bell 412 helicopters

Strategic Significance and Interoperability

The exercise emphasized the importance of interoperability among allied forces. By integrating various aircraft and systems, participating nations enhanced their ability to conduct joint operations effectively. The inclusion of advanced platforms, such as the Israeli G550 and the U.S. KC-46, provided valuable opportunities for cross-training and knowledge exchange.

Notably, Iniochos 2025 marked the first known instance of Israel and Qatar participating in the same military exercise, highlighting a unique moment of indirect cooperation amid complex regional dynamics.

Training Environment and Scenarios

The Hellenic Air Force’s Air Tactics Center designed the exercise scenarios to reflect contemporary threats and operational challenges. The training environment included varied terrains and simulated contested airspace, providing participants with realistic conditions to test their capabilities. Scenarios ranged from localized crises escalating into full-scale conflicts, requiring coordination across air, land, and maritime domains.

The use of the HAF’s Synthetic Training Squadron’s F-16 Tactical Simulators expanded the exercise into the virtual domain, allowing for complex mission planning and execution without the constraints of physical flight operations.

Iniochos 2025 reinforced the Hellenic Air Force’s role as a central player in promoting regional stability and defense cooperation. The exercise’s expanding scale and participation reflect its value as a platform for enhancing tactical proficiency, fostering interoperability, and strengthening strategic alliances. As global security challenges evolve, exercises like Iniochos remain vital for preparing allied forces to operate cohesively in complex operational environments.
