Unalaska, AK – The Missile Defense Agency's Sea-Based X-Band Radar has returned to Hawaii from the Aleutians and isn't expected back in Alaskan waters until the end of this year.

The Honolulu Advertiser reports today that the SBX is in Pearl Harbor now, where it's scheduled for $27 million worth of repairs and upgrades. The giant radar is eventually supposed to be stationed offshore from Adak Island, although its originally scheduled departure from Hawaii last year was delayed because of ballasting problems.

The SBX was in waters near the Aleutians in February for at-sea trials, and participated in tests of the MDA's ballistic missile defense system in March.
