Sea Based X-Band Radar (SBX)
Abstract
The SBX is an advanced X-Band radar that provides the capability for mid-course acquisition, tracking, discrimination and hit-assessment of ballistic missiles. The SBX radar is mounted on a mobile, ocean-going, semi-submersible platform, enabling it to cover any region of the globe. The SBX supports the Ballistic Missile Defense System (BMDS) Homeland defense mission by tracking and discriminating sophisticated Intercontinental Ballistic Missile (ICBM) threats. SBX Multiple Operations and Test Support status includes 230-days at sea per year for BMDS flight and ground test participation while remaining recallable to an active, operational status when indications and warnings signal the need for enhanced discrimination. The SBX is located in a Pacific port when not required at sea. The SBX maintains vessel certifications for operations at sea as well as software compatibility with the BMDS. FY 2017 Amended Budget Request Justification: $+24.500M is required to address emergency warfighting readiness requirements to ensure readiness of the BMDS. $+9.400M Project MX46-SBX Radar Dev Support/XBR Operations and Support to 1) extend SBX Operations to support NORTHCOM readiness requirements, 2) address emerging DoD Execution Order requiring implementation of a DoD Regional Clock for the BMDS to improve warfighter readiness by ensuring integrity and availability of positioning data, and 3) update X-Band Radar and GMD Fire Control (GFC) interfaces to the x86 architecture to resolve incompatibility and increase radar availability. $+15.100M Project MX46-SBX Radar Dev Support/Vessel Operations and Support to 1) upgrade and obtain military certification for flight deck use for helicopters up to 16 tons, day or night without maintenance facilities (NAVAIR Level 2 Class 3) to support passenger transfer, resupply and increase radar availability.
