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?
As it stands, the planned strategy of forsaking arms control in the name of coercive diplomacy is bound to backfire. The Pentagon should tread carefully, lest it invites Russia to develop strategic weapons it has no method or intention of countering.
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.
