§ Lord Kennetasked Her Majesty's Government:
Whether it is their intention to allow United States forces in the United Kingdom or in the United Kingdom's dependencies to deploy ballistic missile defences intended to protect United States forces while not protecting the adjacent civil population or property; and, if so, what control they would exercise. [HL1720]
§ Baroness Symons of Vernham DeanThe Anti-Ballistic Missile Treaty prevents the deployment by the US of systems to counter strategic ballistic missiles outside its national territory.
There are no systems to counter theatre ballistic missiles deployed in the UK or our Overseas Territories. We would consider a request from the US to deploy such a system when and if it was made.
