J-600T Yıldırım (Thunderbolt) is a short-range ballistic missile developed by Roketsan based on the Chinese B-611,[1][2] it is designed to attack high-value targets such as enemy air defence installations, C3I centers, logistics and infrastructure facilities as well as providing fire support to friendly artillery by expanding the area of effect.
Turkey decided to seek for other alternatives, mainly focusing on full sovereignty over critical technologies in order to establish a self-sufficient national infrastructure for the design and development of guided missiles.
The same vehicle is also used for the Turkish-built T-122 Sakarya and T-300 Kasırga MBRL (Multi Barrel Rocket Launcher, or MLRS) systems, providing advantage in logistics.
The missile's flight is controlled by an INS (Inertial Navigation System) which feeds trajectory correction command inputs to the four moving wings at the nozzle section.
