Pentagon budget 2021: MDA seeks funding to keep SBX missile defence radar at sea longer

SBX – a powerful radar atop a re-purposed oil rig displacing more than 50,000 tonnes in the Pacific – is slated to spend 305 days at sea and 60 days in port for maintenance, and then 330 days at sea annually from FY 2022–25, according to MDA budget documents.
