The Sea-Based X-Band Radar (SBX-1) is a floating, self-propelled, mobile active electronically scanned array early-warning radar station designed to operate in high winds and heavy seas. It was developed as part of the Missile Defense Agency's Ballistic Missile Defense System. The radar is mounted on a fifth generation CS-50 twin-hulled semi-submersible drilling rig. Conversion of the vessel was carried out at the AmFELS yard in Brownsville, Texas; the radar mount was built and mounted on the vessel at the Kiewit yard in Ingleside, Texas. It is nominally based at Adak Island in Alaska (though, has never put into port at Adak). It has spent most of its time at Pearl Harbor in test status, having never become operational, and has received criticism for falling short of program expectations.〔 == Specifications == *Vessel length: *Vessel height: from keel to top of radome *Vessel draft: approximately when in motion or not on station; approximately when on station *Vessel stability: remains within 10 degrees of horizontal on station (fully passive stabilization) *Cost: *Crew: Approximately 75-85 members, mostly civilian contractors *Radar range: *Displacement: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sea-based X-band Radar」の詳細全文を読む スポンサード リンク
