UK authorises US use of bases to strike Iran
Change
The UK authorised the United States to use British military bases to carry out strikes on Iranian missile sites attacking ships in the Strait of Hormuz.
Why it matters
British ministers authorised on 20 March 2026 U.S. use of U.K. bases under a collective self‑defence framework. The authorisation explicitly includes U.S. defensive operations to degrade missile sites and capabilities used to attack ships in the Strait of Hormuz. UK bases are made available to host and support U.S. strike operations against those identified missile assets. Prime Minister Keir Starmer said Britain would not be drawn into a war and had initially rejected a U.S. request.
Implications
- · U.S. strike operations to degrade Iranian missile sites can be staged and supported from UK military bases.
- · UK defence and base operators will provide basing, logistics, and support functions for those operations.
Who is affected
- · U.S. military forces conducting strike operations
- · UK defence and base operators
- · Maritime shipping operators
What to watch
- · Authorisation effective 20 March 2026.
