According to the official version is SBX-1 i a mobile underwater radar installation and missile defence programme intended to be placed in the open sea and withstand the harshest weather conditions.

SBX-1 is part of the Ground-Based Midcourse Defence (GMD) system developed by the Missile Defense Agency (MDA). The decision to place the system on a mobile platform at sea was to allow the vessel to be moved to areas where it is needed for better missile defence.

The radar antenna is 384 m2 in size and has 45,000 solid-state transmitting and receiving modules on an octagonal flat base that can move ±270 degrees in azimuth and 0 to 85 degrees elevation and a total of 22,000 modules. Maximum azimuth and elevation speeds are about 5-8 degrees per second. In addition to the physical movement of the base, the beam can be electronically controlled beyond the drill sight (details are secret). This configuration allows the radar to distinguish and track targets over a very long distance.

The radar beam can see a baseball-sized object at a distance of 2,500 miles. Some 69,632 multisection circuits are used in the radar to transmit, receive and amplify signals.

The platform can store supplies and fuel for a period of 60 days. Besides the energy consumed by the radar, the thrusters that propel the ship are electric and require considerable power. To support all other electrical equipment, the ship currently has six 3.6-megawatt generators (12-cylinder Caterpillar diesels). The generators are located in two compartments, one to port and one to starboard.

Derived from the radar used in the THAAD theatre ballistic missile defence system, it is part of the US Missile Defense Agency's (MDA) layered ballistic missile defence system (BMDS). A key difference from Aegis is the use of the X-band in the SBX. Aegis uses the S-band and Patriot uses the higher C-band. The frequency of the X-band is even higher, so the shorter wavelength allows for finer resolution of tracked objects.

The system was developed by Boeing between 2002 and 2005 and long kept secret from the general public. The cost is $900 million. The platform was first seen on 09 January 2006 when the ship entered Pearl Harbor for repairs.

The Co2 pollution caused by this platform idling is equivalent to the annual emissions of 500,000 diesel vehicles. However, this is not a concern for the Americans. any more less than the disruption of earth frequencies, fauna and flora.

Nominally, the SBX-1 is assigned to the Port of Adak in Alaska, but to date it has never appeared in that port.

Reportedly, the SBX-1 is the only one of its kind. Since July 2011, though, other smaller US radars have been circulating in the Pacific picking up the slack not covered by SBX-1.

Some say SBX-1 is much more than a missile defence and radar observation system, would be part of HAARP and used for climate manipulation in, among others, Europe. The video below shows a covert recording of the system in operation.
