MHAC is a group of committed people working to bring public awareness and scrutiny to the issue of the presence and roles of the US Visiting Forces and their Agencies at Menwith Hill.  We recognise that Menwith Hill is part of a US global network of military activity and intelligence that now reaches into space. 

We hold regular demonstrations and support research into the impact of the base. We are totally committed to non-violence.

The Menwith Hill Accountability Campaign seeks to build on the work previously undertaken by the Campaign for the Accountability of American Bases (CAAB).
