"The Sea Based X-Band Radar is the world's largest floating phased array X-band radar. It is operated by the US Department of Defense (Missile Defense Agency) and its movement and location is classified. In 2005 it was engaged in a 52-day deployment in the Gulf where it completed more than 100 major test activities. The 52-day deployment started in late August and ended on Oct. 14, 2005.

"Air Force Lt. Gen. Henry 'Trey' Obering, director of the MDA, said it had demonstrated the ability to achieve most of its major operational and sustainment capabilities.

"SBX was in the Gulf at the same time as Hurricane Katrina formed on August 23, 2005. On Saturday, August 27, 2005 the storm reached Category 3 intensity on the Saffir-Simpson Hurricane Scale, becoming the third major hurricane of the season.
