Sea-Based Radar to Watch North Korea
From Wiki
SBX-1 is part of the Ground-Based Midcourse Defense (GMD) system being deployed by the MDA. Being sea-based allows the vessel(s) to be moved to areas where they are needed for enhanced missile defense. Fixed radars provide coverage for a very limited area due to the curvature of the Earth. The primary task SBX will carry out is discrimination (identification) of enemy warheads from decoys, followed by precision tracking of the identified warheads.
Washington (CNN) — The U.S. Navy is moving a warship and a sea-based radar platform closer to the North Korean coast in order to monitor that country’s military moves, including possible new missile launches, a Defense Department official said Monday.
The decision to move at least one ship and the oil rig-like SBX-1 are the first of what may be other naval deployments, CNN has learned.
