The Boeing Company announced that the Sea-Based X-Band Radar (SBX) mooring system has been installed at SBX's homeport in Alaska, completing a key piece of infrastructure for the missile defense sensor. Manson Construction, a Boeing subcontractor, used tugs, barges and cranes to place the mooring system's eight anchors on the bottom of Kuluk Bay. Heavy machinery aboard a barge then dragged the 75-metric-ton anchors, embedding them into the sea bed. The construction team completed the installation three weeks ahead of schedule. When SBX visits its homeport of Adak, Alaska, a small island in the Aleutian Islands, it will be chained to the anchors to keep it stationary in Kuluk Bay. SBX is a new sensor developed by Boeing for the U.S.
