Anti-Satellite Weapons (ASAT's) are developed with the purpose of destroying satellites. The United States, China, and the Russian Federation have successfully tested anti-satellite missiles. Anti-satellite weapons are an emerging technology in response to the ever increasing militarization of space.

On October 23, 2007, China launched its first orbiter around the moon. Chinese submarines tested a remote navigation system, that allowed the orbiter to change course based on signals sent from earth. The test sparked U.S. fears that China was attempting to develop a space weapon capable of destroying satellites.

On February 12, 2008, Russia and China reported that they will present a treaty to The United Nations hoping to restrict the use of space weapons. The United States, which presumably leads the way in space technology, has maintained a stance against international regulation of space weapons.
