Floatin’ Smokey: The USA’s SBX Radar
August 16/21: Hercules Great Eastern won a $9.1 modification to exercise and fund the second 12-month option on a firm-fixed-price contract with reimbursable elements for the offshore support vessel Hercules. This vessel will be utilized to support refueling and resupply of the Sea-Based X-Band Radar (SBX-1). The contract includes a 12-month base period, three 12-month option periods, and one 11-month option period. Work will take place in the US Pacific Command’s area of responsibility. Estimated completion date is July 15, 2024.
As rogue state proliferation by the likes of North Korea made missile defense a growing priority for nations including the USA, Japan, and Israel, the USA began to look at the linchpin of any defense: powerful radars that could both track ballistic missiles, and guide interceptors. The USA has its BMEWS tracking system, but that would not serve. America’s Safeguard ABM system was dismantled long ago – though Russia still maintains its counterpart System A-135 network around Moscow. Something new would be needed.
Enter Raytheon’s new XBR radar, based on an SBX-1 platform that looks a lot like a mobile oil drilling rig. Basing the radar at sea offers numerous advantages. One is the obvious ability to move the radar as threats materialize, allowing much greater coverage with fewer radars. Another is the ability to protect allies, without having to invest in expensive systems whose regional capabilities and value to the USA could be put at risk by the decisions of a single foreign government. In exchange for this freedom from political interference, of course, the designers must contend with nature’s interference in the stormy Pacific.
Boeing SBX system is linked to its land-based GMD (Ground-based Mid-course Defense) missile system but can also operate with other naval and land elements.
