Türkiye’s domestically developed long-range air defense missile system, Siper, has successfully passed its serial production acceptance tests, marking a decisive leap in the country’s bid for a self-sufficient and layered national air shield.
The breakthrough was announced Wednesday by Defense Industry Agency (SSB) President Haluk Görgün, who hailed the development on the NeXT Sosyal platform as a key moment in strengthening the nation’s airspace security, widely known as the “Sky Homeland.”
Developed by leading Turkish defense firms ASELSAN, ROKETSAN, and TÜBİTAK SAGE under SSB’s coordination, the Siper system is designed to intercept high-altitude threats, including fighter jets, ballistic missiles, cruise missiles, and drones, at ranges reportedly reaching up to 150 kilometers.
The missile’s successful completion of acceptance tests confirms it is ready for serial production and integration into the Turkish Armed Forces' inventory.
Siper is the crown jewel of Türkiye’s multi-layered air defense project known as the Steel Dome, which combines short, medium, and long-range systems into a seamless, networked structure.
The system’s precision radar and guidance technologies allow it to track and engage multiple targets simultaneously, even under complex threat scenarios.
Designed to operate in tandem with other indigenous systems such as HİSAR-A and HİSAR-O, Siper closes the high-altitude gap and completes Türkiye’s national air defense grid.
The Steel Dome itself is a layered framework that integrates various systems to protect against low-, medium-, and high-altitude aerial threats. HİSAR-A counters close-range dangers like helicopters and drones, while HİSAR-O handles medium-range threats.
Together with Siper, these components are linked through advanced command-and-control infrastructure and early warning radars, including the EIRS, to enable real-time responses to evolving air threats.
Siper’s journey began in 2018 as part of Türkiye’s strategic drive to reduce reliance on foreign defense systems.
In the years that followed, Turkish engineers worked to develop a system that could rival global equivalents such as the American Patriot and Russian S-400. By 2021, prototype testing was underway, validating the missile’s guidance, radar, and propulsion systems.
The announcement on Wednesday, confirming successful serial production tests, now paves the way for full-scale deployment.
The system’s emergence carries broader geopolitical and industrial significance.
Strategically, it bolsters Türkiye’s deterrent posture amid regional instability and growing aerial threats.
Economically, it underscores the capabilities of Türkiye’s defense sector, enhancing its potential to attract international buyers and increasing the country's footprint in the global arms market.
Technologically, it demonstrates the growing sophistication of Türkiye’s engineering base and its ability to deliver complex defense platforms independently.
In his statement, Görgün emphasized the collaborative spirit and national vision driving the program: “Siper, which undertakes high-altitude air defense missions, has further solidified its place in the inventory with successful tests. This development represents a critical milestone in Türkiye's layered air defense architecture. We are resolutely advancing on this path with the efforts of our engineers, the cooperation of our institutions, and the support of our nation.”
Looking ahead, the SSB and its partners are expected to continue refining the system.
Future variants may feature longer range, enhanced countermeasures, or integration with artificial intelligence.
The success of Siper also lays the groundwork for next-generation programs, including potential hypersonic missile defenses or space-based early warning platforms, as Türkiye seeks to keep pace with global threats and lead innovation in air defense technologies.
