- What is the UK Ministry of Defence?
- The UK Ministry of Defence (MoD) is the government department responsible for British defence policy, commanding the Royal Navy, British Army, and Royal Air Force, and maintaining the Trident nuclear deterrent. It was founded in 1964 through a merger of the War Office, Admiralty, and Air Ministry.Source: MoD
- Was Diego Garcia attacked in 2026?
- Yes. Iran launched two intermediate-range Ballistic Missiles at the joint UK-US base on Diego Garcia on 19 March 2026. One malfunctioned in flight; the other was intercepted. The MoD condemned the strikes as a threat to British interests and British allies.Source: UK MoD
- How much does the UK spend on defence?
- The UK defence budget for 2024-25 is approximately £59.6 billion, equivalent to around 2.3% of GDP. This meets the NATO 2% threshold but is widely considered inadequate given simultaneous active commitments in 2026.Source: MoD / HM Treasury
- Is Diego Garcia British territory?
- Yes. Diego Garcia is part of the British Indian Ocean Territory (BIOT), a British Overseas Territory. The UK leases the island to the United States under a defence agreement. The 2026 Iranian missile strike was therefore an attack on British sovereign territory.Source: UK MoD
- How does UK defence spending compare to France and Germany?
- The UK spends approximately 2.3% of GDP on defence (2024-25), broadly comparable to France (~2.1%) and well above Germany (~2.0% following years of under-investment). Both the UK and France maintain independent nuclear deterrents; Germany does not.Source: NATO / IISS
Background
The UK Ministry of Defence (MoD) is responsible for defence policy, commanding the Royal Navy, Royal Air Force, and British Army, and maintaining the Trident nuclear deterrent. Founded in 1964 through a merger of the War Office, Admiralty, and Air Ministry, it operates a global network of overseas bases, including the joint UK-US facility on Diego Garcia in the British Indian Ocean Territory.
In March 2026, Iran launched two intermediate-range Ballistic Missiles at Diego Garcia; one was intercepted. The MoD condemned the strikes as ‘a threat to British interests’, placing UK sovereign territory in an active war theatre for the first time since the Falklands. The attack also confirmed Iran’s true missile range at 4,000 km, double Tehran’s publicly stated ceiling.
The MoD is managing simultaneous exposure in two active theatres: the Iran conflict via Diego Garcia’s role as a forward strike base, and ongoing military support to Ukraine since 2022. Defence spending at approximately 2.3% of GDP faces sustained pressure; critics argue the threat environment has outpaced the budget cycle. A mid-sized power with first-tier commitments, the MoD must now answer whether its resources match its reach.
