Despite some missile defense advocates’ claims that 24 satellites could form the basis of a boost-phase space-based missile interceptor (SBI) system, many physicists do not agree. A better question is how could a satellite constellation of this size best contribute to U.S. missile defense?
The deployment of a space-based missile intercept layer would require launching hundreds or thousands of weapons into space – an expensive, inefficient, and provocative proposition.
The idea of space-based missile interceptors is not new nor prohibited, but it is a bad idea. This piece looks beyond the policy arguments and explores the inefficiencies and vulnerabilities of space-based missiles.
