The Ministry of Defence (MOD) protects the security, independence and interests of our country at home and abroad.
We work with our allies and partners whenever possible. Our aim is to ensure that the armed forces have the training, equipment and support necessary for their work.
The MOD works with the United States on joint overseas operations and contingency planning, bilateral defence co-operation, interoperability and engages on defence trade.
Our team in the United States assists this work and communicates the broader transatlantic defence relationship, elevates the UK’s interests and reputation and provides high-quality advice and reporting to the UK on all aspects of defence business.
The MOD is responsible for: defending the UK and its overseas territories, providing strategic intelligence, providing nuclear deterrence, supporting civil emergency organisations in times of crisis, defending our interests by projecting power strategically and through expeditionary interventions, providing a defence contribution to UK influence and providing security for stabilisation.
The British Defence Staff in the United States comprises some 750 military and civilian MOD personnel based in over 30 states across the US. Their mission is to protect and advance the UK and its interests by reinforcing the transatlantic defence and security relationship.
