The China Aerospace Studies Institute (CASI) is a United States Department of the Air Force think tank which examines all facets of the People's Republic of China and Chinese Communist Party's efforts to project power in the air and space domains.

CASI provides expert research and analysis supporting decision and policy makers in the Department of Defense and across the U.S. government.

CASI accomplishes its mission through conducting the following activities: CASI supports the U.S. Defense Department and the China research community writ-large by providing unclassified research on Chinese aerospace developments in the context of U.S. strategic imperatives in the Asia-Pacific region.

Primarily focused on China’s Military Air, Space, and Missile Forces, CASI capitalizes on publicly available native language resources to gain insights as to how the Chinese speak to and among one another on these topics.
