Star Advertiser: The Sea-Based X-Band Radar (SBX)a floating, self-propelled mobile radar stationhas been spending a lot of time in Hawaii. Although nominally based at Adak Island in Alaska, it roams the Pacific Ocean to detect incoming ballistic missiles. According to the Missile Defense Agency, the SBX has been habitually returning to Pearl Harbor because it has the “correct mix of labor and supplies to accomplish needed maintenance and repairs.” The SBX’s unusual appearance, a multi-legged platform topped by what looks like a giant golf ball, is becoming a tourist attraction at Ford Island, where it has moored 11 times and spent a combined total of more than a year and a half in port.
