Anti-Satellite Weapons
(ASAT)
ASAT: things to consider
Deployment of weapons in space as oppose to military use
of space;
Blurry line between anti-missile and anti-satellite
technologies;
Various methods of destroying satellites with ground-based
and orbital platforms theoretically possible;
Numerous projects under consideration during the Cold
War but deployment is limited;
Multi-component nature of ASAT systems (tracking, nav
and launch);
Huge difference in range of ASAT weapons;
Military benefits of ASAT systems remain controversial.
