U.S. deploys Sea based X-Band Radar (SBX) to detect potential North Korean Missile Launch
 
The United States has deployed its Sea-based X-Band radar to the ocean east of Japan to detect any potential North Korean ballistic missile launches. The SBX is a combination of the world's largest phased-array X-band radar carried aboard a mobile, ocean-going semi-submersible oil platform.

U.S. deploys Sea based X-Band Radar (SBX) to detect potential North Korean Missile Launch
 
The United States has deployed its Sea-based X-Band radar to the ocean east of Japan to detect any potential North Korean ballistic missile launches. The SBX is a combination of the world's largest phased-array X-band radar carried aboard a mobile, ocean-going semi-submersible oil platform.

In case of a ballistic missile launch, it would be able to detect the missile and track its trajectory. This data would then be used by other platform (such as US Navy Destroyers in the area) to shoot the missile down.

A Pentagon official said the move was a “routine deployment” that is “not in relation to current events.” The same official said however that the deployement of destroyer USS John McCain was linked to the current crisis.

The SBX is a floating, self-propelled, mobile radar station designed to operate in high winds and heavy seas. It is part of the U.S. Defense Department Ballistic Missile Defense System. The Sea-Based X-Band Radar is mounted on a fifth generation CS-50 twin-hulled semi-submersible drilling rig. SBX-1 is part of the Ground-Based Midcourse Defense (GMD) system being deployed by the Missile Defense Agency. Being sea-based allows the vessel to be moved to areas where they are needed for enhanced missile defense.
