ROKETSAN Advances Türkiye’s Space Ambitions with ŞİMŞEK Projects
Türkiye is taking a significant step toward independent space access as ROKETSAN continues development on its domestic satellite launch systems, known as the ŞİMŞEK 1 and ŞİMŞEK 2 projects. ROKETSAN General Manager Murat İkinci confirmed that both programs are progressing according to their established schedules, aiming to grant Türkiye the capability to launch its own satellites from domestic soil. By integrating advanced propulsion, navigation, and material technologies, these projects strive to position Türkiye among the elite group of nations capable of conducting independent space launches, moving beyond simple satellite manufacturing to creating a robust, sovereign launch infrastructure.
- The ŞİMŞEK 1 system is designed to place a 400-kilogram payload into a 500-kilometer orbit.
- The ŞİMŞEK 2 project aims to carry a 1.5-ton payload into orbits up to 700 kilometers for both national and commercial missions.
- ROKETSAN is developing these platforms as a strategic foundation to eventually incorporate reusable rocket technologies to reduce operational costs.

ŞİMŞEK 1 Targets Medium-Scale Orbital Capabilities
The first phase of the initiative, ŞİMŞEK 1, focuses on delivering a 400-kilogram payload to an altitude of approximately 500 kilometers. This system is designed to serve as a versatile carrier for various types of spacecraft and mission equipment. Beyond the technical specs, the project emphasizes the importance of launching from Turkish territory, which would grant the nation complete operational control over its orbital assets. This transition represents a major technological threshold, requiring the simultaneous development of subsystems like thermal management, avionics, and flight control systems.
ŞİMŞEK 2 Expands Commercial Launch Potential
Building on the initial platform, the ŞİMŞEK 2 project aims to scale up capacity significantly. Designed to transport a 1.5-ton payload into 700-kilometer orbits, this system is intended to function as a commercial launch platform. ROKETSAN plans to leverage international collaborations to provide satellite launch services to other nations, potentially turning the project into a revenue-generating asset for the Turkish economy. By entering the global launch market, Türkiye aims to solidify its position within the broader, multi-billion-dollar space ecosystem. {{WP_IMAGE_2}}
Reusable Technology Shapes Future Design Strategies
While the initial iterations of the ŞİMŞEK series will not feature reusable stages, ROKETSAN is already laying the groundwork for such technology. The development team is qualifying subsystems in the current projects that will eventually support reusable rocket architectures. By minimizing the need to manufacture new launch vehicles for every mission, the company hopes to drastically lower the cost per kilogram for space access. This forward-looking approach ensures that the expertise gained today will directly inform the next generation of cost-effective, sustainable launch vehicles.
Engineering Ecosystem Supports Space Independence
The success of the ŞİMŞEK program relies on a vast network of engineering expertise. ROKETSAN is collaborating with universities, government bodies, and over 2,500 industrial partners to refine critical technologies, including high-performance engines and navigation systems. This effort integrates the existing defense industry supply chain into the space sector, creating a synergetic environment where high-end engineering skills are shared across different aerospace platforms. 
Strategic Goals Align with National Space Vision
The ŞİMŞEK projects are integral to Türkiye’s broader National Space Program and its ambitious goals, including lunar missions. These launch platforms serve as essential stepping stones, providing the necessary infrastructure to test and validate the components required for deep space exploration. While a specific date for the inaugural launch has not been disclosed, the ongoing progress remains a cornerstone of the nation’s technological roadmap, marking a pivotal shift toward achieving full autonomy in space missions.
