US Missile Defense Agency (MDA) towed a Sea-Based X-Band Radar (SBX) to Vigor Shipyard on Harbor Island of Seatle for three months of work. So local newspapers print photos of it (radar).
A Brief History of Sea-Based X-Band Radar-1. MDA History Office, May 1, 2008.

("The SBX-1 serves as the largest and most sophisticated phased array electro-mechanically steered X-band radar in the world. * * * the radar can track objects as they fly toward, over, and away from the vessel. * * * which is capable of seeing an object the size of a baseball at a distance of 2,500 miles")
It appears US has only one.

(It is nomimaly based at Adak Island in Alaska (though, as of early 2011, has never put into port at Adak) but can roam over the Pacific Ocean to detect incoming ballistic missiles)
