Developed with our own technology, the K9 Thunder is the world’s most advanced self-propelled howitzer. The K9 boasts excellent performance with a long shooting range for fire combat and a fast firing speed for real-time, quick-focused fire power. It is a unit capable of quick displacement after shooting, and has excellent maneuverability and survivability. In addition, we have developed customized self-propelled howitzer that meets the requirements of various countries as well as NATO standards. Its operational capability is excellent in a range of environments, from deserts to snowy fields, and it is being exported to overseas countries.

K9 Thunder can fire its first round within 30 seconds from the moment it first receives firing information from the Fire Direction Center (FDC) while in emplaced situation. While moving, it can fire after 60 seconds. After firing, K9 Thunder can quickly move away from its last position in anticipation of the enemy’s counter fire, before firing its next shot.
