Welcome to the website for the Sea-Based X-Band Radar Environmental Assessment
This website has been established to provide you with a source for
information about the preparation of the EA.
The Missile Defense Agency (MDA) needs to perform maintenance work on the SBX Radar Vessel. The vessel’s thrusters, which help move it through the water, require periodic maintenance to retain American Bureau of Shipping/U.S. Coast Guard certification, which is required for the vessel to operate. Thruster maintenance is needed to maintain a full suite of radars for anti-ballistic missile testing and defense.
MDA also needs to perform additional maintenance and repair on the vessel. Work includes repainting needed areas, inspecting and repairing other vessel components, and upgrading some internal systems. MDA will not operate the X-Band Radar while in port.
The required maintenance will be performed at the deepwater shipyard facility at
Vigor Shipyards (Formerly Todd Pacific Shipyards), in Seattle, Washington. In the event that
Vigor Shipyards is not available to perform required maintenance activities, a contingency location would be selected. The potential environmental effects of the maintenance and repair activities at two contingency locations are analyzed in the Sea-Based X-Band Radar Environmental Assessment.
The required maintenance can be accomplished only at a deepwater port. The two contingency locations on the West Coast that could meet the specific deep-water maintenance requirements are:
- Naval Air Station North Island – San Diego, California
- Naval Station Everett – Everett, Washington
Maintenance and repair work may begin in the spring of 2011, and will take approximately three months to complete.
