1) Improve the Navy’s Aegis-based missile defense system. Here we’d be building on working technology -- technology that has already proven itself in the field on the Navy’s Aegis ships. The system has been modified so that it can shoot down short-range to intermediate-range ballistic missiles and detect and track ballistic missiles of all ranges. The next step is to adjust it so it can shoot down long-range ballistic missiles in the late “midcourse” stage of flight.
2) Build a layered missile defense. We need a network with land, sea, air and space capabilities. That means locating sensors throughout the world and in space. It also means we have to increase the number of interceptors we have to counter long-range missiles. With a layered system, our chances of destroying an incoming missile are greatly increased.
3. Develop space-based interceptors. “All but the very shortest-range ballistic missiles travel through space,” Spring and Bendikova write. “Thus, the most capable missile defense system would locate interceptors where the missiles would fly -- in space.”
There’s no excuse to delay or shortchange our ability to defend ourselves as fully as possible. We need an immediate and comprehensive missile defense. With it, we can deprive our enemies of a powerful weapon. What are we waiting for?
