EFES 2026: Turkey’s Largest NATO Exercise with 50 Countries — TB3, Iron Dome, and Domestic Weapon Showcase

According to sources from the Presidency of Defense Industries (SSB) and Daily Sabah, the EFES-2026, the largest joint exercise conducted by the Turkish Armed Forces (TSK), took place between April and May 2026 at the live-fire range in Doğanbey, Seferihisar, İzmir. The peak of the live-fire phase, “Distinguished Observer Day,” occurred on May 20-21, 2026. Defense Minister Yaşar Güler, along with defense ministers and chiefs of staff from NATO allies and partner countries, observed the exercise on-site.

Background: From Dependency to Freedom in a Decade

EFES-2026 was the most comprehensive showcase of the transformation recorded in Turkey’s defense industry over more than a decade. According to Quwa Defence News, the exercise “directly reflected a defense industry that has transitioned from dependency to freedom within a decade and is now competing for export contracts in Central Asia, Africa, and Europe.” The total of export agreements signed at the SAHA 2026 Defense and Aerospace Fair, which took place before EFES-2026, exceeded $8 billion; the TSK exercise served as a ground proving the operational depth of this success.

Critical Axes of the Exercise

EFES-2026 was conducted with a multidomain joint operation scenario that encompassed land, air, sea, and cyberspace at a level of complexity far exceeding previous years. During the exercise, fifty new domestic systems were deployed.

Naval dimension: The TCG Anadolu light aircraft carrier enabled the Bayraktar TB3 UAVs to operate from the sea without the need for land takeoff — this is Turkey’s most critical operational capability in a competitive global defense industry. In addition to MİLGEM-class corvettes, FNSS ZAHA amphibious assault vehicles and YLCT landing ships (C-159, C-160) have realized amphibious operation scenarios.

Aerial defense dimension: The integrated air defense architecture developed by STM, defined by Quwa as “Steel Dome”; provided layered defense through the simultaneous operation of the SİPER long-range, HİSAR-A/O short-medium range, and SUNGUR very short-range systems. This architecture was previously only included in planning documents.

Diplomatic Dimension: Syria and Libya

According to Defence Turkey, the most striking diplomatic aspect of EFES-2026 was the materialization of Turkey-Syria security rapprochement following the collapse of Bashar al-Assad’s regime: Syrian forces participated in the EFES exercise for the first time since 2011. On the other hand, the conflicting eastern and western forces of Libya were present together in the same area — a reflection of the long-standing Turkish mediation in the field.

What Does It Mean for Turkey?

EFES-2026 is critical for the validation of Turkey’s maturity in the defense sector in front of NATO allies. Turkey, now recognized not just as a supplier but as an integrator of systems, exporter, and shaper of doctrine, sent several concrete messages with this exercise:

• The TB3 + TCG Anadolu combination makes Turkish naval aviation one of NATO’s most flexible unmanned platforms. Very few countries have this capability.
• The KARGU autonomous swarm is a concept that NATO partners are closely monitoring for its capacity to create high mass at low cost.
• The Iron Dome represents the most advanced step towards reducing dependence on imported systems (Patriot, NASAMS) by transitioning air defense to domestic procurement.
• The $8 billion export volume of SAHA 2026 coincides with the exercise: recipient countries were able to observe the performance of the systems they purchased in action.

Frequently Asked Questions

When and where was EFES-2026 held? The exercise took place at the Doğanbey live-fire range in Seferihisar, İzmir, from April 11 to May 22, 2026. The live-fire peak occurred on May 20-21.

How many countries participated in the exercise? A total of 10,388 personnel from 50 countries participated. Of this personnel, 1,305 are members of allied and partner countries.

Why is the Bayraktar TB3 important? The TB3 is the first Turkish UAV with foldable wings that can take off from the TCG Anadolu light aircraft carrier. This provides the Turkish Armed Forces and recipient countries with the capability for land-independent maritime drone operations.

How does the KARGU swarm system work? Developed by STM, KARGU allows a single operator to simultaneously manage 20 autonomous drones. The system features an AI-based target detection and identification module.

Why did Syria participate in EFES? The participation reflects the exercise dimension of the security dialogue initiated by the new Syrian administration with Turkey after Assad. Joining EFES is considered one of the concrete steps in Turkey’s normalization process with Damascus.

Conclusion

EFES-2026 was an event that confirmed the transformation recorded in Turkey’s defense industry over the past decade, not only on paper but also in a joint exercise involving 10,000 personnel. The TB3s taking off from TCG Anadolu, the KARGUs operating in swarms, and the integrated fire of the Iron Dome demonstrated that Turkey is now a defense power that both develops systems and proves them in real environments.
