"These missiles can destroy US and allied space systems in low Earth orbit, making intelligence, surveillance, reconnaissance and communications satellites vulnerable," the report states, adding that both Russia and China are looking into counterspace directed-energy weapons that are "designed to produce reversible or non-reversible effects against space systems by emitting highly focused radiofrequency or laser energy."
The NASIC report lists a range of potential space attacks, which includes jamming global navigation and communication satellites used for military operations; using anti-satellite missiles to shoot down low Earth orbit satellites; and physical attacks against ground sites and infrastructure that support space operations.
In an effort to realize the possibility of "foreign competitors" actually using anti-satellite missiles to strike down US satellites, the report cites an incident from 2007 in which China used said technology to destroy Fengyun-1C, an aging Chinese weather satellite that had been orbiting Earth since May 1999.
At the time, Harvard astronomer Jonathan McDowell told the New York Times that China's actions marked the "first real escalation in the weaponization of space that we've seen in 20 years."
The NASIC report comes days after the Defense Intelligence Agency (DIA) released a review last week on the core capabilities of China's military. "The Military Power series of unclassified overviews is designed to help the public achieve a deeper understanding of key challenges and threats to US national security," a releaseon the DIA report reads.
In December of 2018, the US Government Accountability Office released its own take on the topic, revealing that there are no countermeasures or effective defenses that exist that could tackle hypersonic weapons created by Russia and China.
