Agency for Defense Development was established in August 1970 under the banner of the self-reliable defense. ADD is the only South Korean national agency for research and development in defense technology funded by Defense Acquisition Program Administration. Its purpose is contributing to enforcing the national defense, to improving the national R&D capacity, and to fostering the domestic defense industry. Wikipedia.
