    SBX-1 92k SBX-1 being carried by the heavy lift vessel Blue Marlin, entering Pearl Harbor, HI., 9 January 2006. Blue Marlin transported SBX-1 from her builders yard at Corpus Christi, TX. to Pearl Harbor where the platform was placed in service.  
    SBX-1 208k The heavy lift vessel MV Blue Marlin sits moored in Pearl Harbor, Hawaii, with the Sea Based X-Band Radar SBX-1 aboard after completing a 15,000-mile journey from Corpus Christi, Texas. SBX-1 is a combination of the world's largest phased array X-band radar carried aboard a mobile, ocean-going semi-submersible oil platform. It will provide the nation with highly advanced ballistic missile detection and will be able to discriminate a hostile warhead from decoys and countermeasures. SBX-1 will undergo minor modifications, post-transit maintenance and routine inspections in Pearl Harbor before completing its voyage to its homeport of Adak, Alaska in the Aleutian Islands.
