Turkey's massive Ay Yıldız Müşterek Karargâhı (Crescent and Star Joint Headquarters) officially began its symbolic operations this week, marking a significant milestone in the country's defense infrastructure. The complex, which President Recep Tayyip Erdoğan described as a structure that will 'instill fear in enemies and confidence in allies', is set to host two high-profile events within a span of seven days: the Ministry of National Defense's weekly press briefing and a reception for visiting NATO defense ministers and their delegations ahead of the NATO summit.
Symbolic Openings
The first event, scheduled for tomorrow, will see the Ministry of National Defense's weekly press briefing held at the headquarters for the first time. This move symbolizes the gradual activation of the facility, which is still under construction. The second event, on July 7, will host a reception in the Yıldız (Star) section of the complex for defense ministers attending the NATO summit. These events are designed to showcase Turkey's commitment to modernizing its command and control capabilities.
Massive Scale and Design
Located in Ankara's Etimesgut district on a sprawling 12.6 million square meters of land, the Ay Yıldız complex is one of the largest military headquarters in the world. The covered area spans 890,000 square meters, making it larger than the Pentagon, the headquarters of the United States Department of Defense. The design incorporates two main sections: the Ay (Crescent) and the Yıldız (Star). The Star section is largely completed, while work on the Crescent section continues.
The central feature of the complex is a crescent-shaped building that houses shared facilities, including conference halls with capacities of 1,680, 502, and 251 people. Surrounding this central structure is a 23,000-square-meter ceremonial area in a circular form. At the front of the site, a star-shaped welcome and exhibition building greets visitors. The facility is designed to accommodate 15,000 personnel, bringing together the Ministry of National Defense, the General Staff, and all three service commands—Land Forces, Naval Forces, and Air Forces—under one roof.
Advanced Security and Technology
The Ay Yıldız complex is not just about size; it incorporates cutting-edge construction technology. From cybersecurity measures to ballistic protection and defense against chemical, biological, radiological, and nuclear (CBRN) threats, every aspect of the design reflects modern military requirements. The use of reinforced concrete and advanced structural engineering ensures resilience against attacks. This level of integration is expected to enhance operational efficiency and coordination among Turkey's military branches.
Comparison with the Pentagon
President Erdoğan has stated that the Ay Yıldız complex will be larger than the Pentagon. While the Pentagon has approximately 600,000 square meters of office space on 116 acres (about 0.47 million square meters), the Ay Yıldız complex covers 890,000 square meters of enclosed space on a much larger land area. This comparison underscores Turkey's ambition to project power and streamline military decision-making. The facility is designed to serve as the nerve center of Turkey's defense, Centralizing command and control functions that previously operated from multiple locations.
Historical Context and Future Plans
The move to Ay Yıldız will end an era for Turkey's historic military headquarters. The current General Staff building, located in Ankara's Bakanlıklar district, was designed by Austrian architect Clemens Holzmeister and completed in 1931. It originally served as the Erkân-ı Harbiye-i Umumiye Riyaseti (General Staff Presidency) after moving from a former agricultural school in Keçiören. The building, with its distinctive 'E' and 'H' shapes, has housed the General Staff and later the Ministry of National Defense. After the relocation, this historic structure will be converted into a museum, preserving its architectural and historical significance.
The Ministry of National Defense also plans to assess the future use of other existing buildings, including the Naval Forces Command headquarters. There is speculation that this building could be repurposed as an annex for the Turkish Grand National Assembly (TBMM). Meanwhile, the Ministry of National Defense and General Staff buildings will be transformed into a museum, allowing the public to explore the history of Turkey's military command.
Phased Move and Integration
The full relocation of personnel and operations to Ay Yıldız is planned for 2028. The move will be coordinated across all commands to ensure uninterrupted operations. Once completed, the complex will drastically improve inter-service cooperation by colocating leadership and staff. This is expected to reduce response times and strengthen strategic planning. The project also includes amenities such as dining facilities, recreation areas, and medical services to support the thousands of personnel who will work there.
The symbolic openings this week are a prelude to the gradual activation of the headquarters. As construction progresses, more functions will be transferred. The Ay Yıldız complex represents a generational investment in Turkey's defense infrastructure, reflecting the country's growing geopolitical ambitions and its commitment to modernizing its military capabilities. The integration of multiple commands into a single high-security campus will likely set new standards for military headquarters in the region.
The reception for NATO defense ministers on July 7 is particularly significant as it will highlight Turkey's role as a key NATO ally. The event will showcase the advanced facilities to international partners, reinforcing Turkey's position within the alliance. With the completion of the star section and ongoing work on the moon section, the headquarters is taking shape as a symbol of national strength and technological progress.
