In recent years, China has made great strides in its space program. Growing Chinese counterspace capabilities are beginning to threaten U.S. space superiority and therefore the ability of the U.S. to support its friends and allies and to deter aggression. To deal with the challenge, the U.S. should maintain and expand robust space capabilities, develop alternatives to space-based systems to reduce American vulnerability, and increase U.S. knowledge and understanding of Chinese space capabilities.
