The Bush plan might also call for the development of sea-based interceptors, which are likely to be modified versions of the land-based interceptors.
The capabilities will include ground-based interceptors, sea-based interceptors, additional Patriot units and sensors on land, sea and space.
The Pentagon plans to develop sea-based interceptors, fit lasers to planes, and to explore the use of firing rockets from space.
But deploying such interceptors would not eliminate the desire for forward-deployed radars.
The planned burnout speed of the ground-based interceptors is reported to be 7 to 8 km/s.
