US plans $4bn boost to UK airbases, files suggest nuclear storage

newsJun 30, 2026961

Pentagon files reported by the Guardian detail a roughly $4 billion package to upgrade US airbases in the United Kingdom, and indicate some new facilities may be designed to store US nuclear weapons. The documents also show $163 million earmarked for Menwith Hill, a long-running secretive spy site in North Yorkshire. The files and related commentary single out other US-occupied RAF sites, including Lakenheath, as part of the wider upgrade program. Reporting has prompted immediate questions about whether the planned facilities would place US nuclear warheads on UK soil and about who would have legal and investigative authority if incidents occurred on those bases. The disclosure is likely to increase political scrutiny in Westminster and among local communities near the bases, and could complicate UK-US defence and basing arrangements as details are clarified and parliamentary oversight resumes.
