The following excerpt from the report summarizes U.S. counterspace capabilities.
The United States has conducted multiple tests of technologies for rendezvous and proximity operations (RPO) in both low Earth orbit (LEO) and geosynchronous Earth orbit (GEO), along with tracking, targeting, and intercept technologies that could lead to a co-orbital anti-satellite (ASAT) capability.
These tests and demonstrations were conducted for other non-offensive missions, such as missile defense, on-orbit inspections, and satellite servicing, and the United States does not have an acknowledged program to develop co-orbital capabilities. However, the United States possesses the technological capability to develop a co-orbital capability in a short period of time if it chooses to.
The following excerpt from the report summarizes Russia’s counterspace capabilities.
There is strong evidence that Russia has embarked on a set of programs over the last decade to regain many of its Cold War-era counterspace capabilities. Since 2010, Russia has been testing technologies for rendezvous and proximity operations (RPO) in both low Earth orbit 9LEO) and geosynchronous Earth orbit (GEO) that could lead to or support a co-orbital anti-satellite (ASAT) capability. Evidence suggests at least two active programs: a new co-orbital ASAT program called Burevestnik that is potentially supported by a surveillance and tracking program called Nivelir.
