"China and Russia, in particular, are developing a variety of means to exploit perceived US reliance on space-based systems and challenge the US position in space," the Defence Intelligence Agency report said on Monday.
The report titled, "Challenges to Security in Space", examines Russian, Chinese, Iranian and North Korean space capabilities, CNN reported.
US satellites play a critical role in everything from navigation, weapons targeting and intelligence gathering, including keeping tabs on North Korea's nuclear weapons programme and monitoring Russian and Chinese military activity.
They also house sensors involved in detecting enemy missile launches.
"China likely will field a ground-based laser weapon that can counter low-orbit space-based sensors by 2020, and by the mid-to-late 2020s, it may field higher power systems that extend the threat to the structures of non-optical satellites," the report said.
The report warned that China also has an operational missile capable of hitting satellites in low-Earth orbit while Russia is in the process of developing one.
