The Navy is contracting TOTE Services to support SBX-1. The company is being awarded with a firm-fixed-price contract
valued at $11.1 million. The company will be responsible for operating and maintaining the Sea-Based X-Band Radar vessel. The X-band radar, also known as the SBX
, was originally planned as a land-based system but a sea-based system became possible when the Bush administration withdrew from the 1972 Anti-Ballistic Missile Treaty. It constitutes a mid-course fire control radar based on a seagoing semi-submersible vessel. The $815 million, mechanically-slewed, X-band phased array assembly is 280 feet tall, and weighs 2,400 tons. The radome alone weighs 18,000 pounds, stands over 103 feet high, and is 120 feet in diameter. Made entirely of a high-tech synthetic fabric, the radome is supported by air pressure alone, and is designed to withstand 130+ mph winds and a “100-year storm” at sea. The radar performs
cued search, precision tracking, object discrimination and missile kill assessment. The in-flight interceptor communication system data terminal transfers commands from the GMD fire control system to the interceptor missile
during its engagement with the target missile. This contract is scheduled for completion by September 2019, but does include several options which could extend the contract until end of March, 2024. The total cumulative value of this contract would rise to $65.3 million, if all options are exercised.
