MOD Supply Base

Our Supply Base

The Strategic Defence and Security Review (SDSR) 2015 committed the UK to spend a minimum 2% of GDP on defence over the next decade.  This commitment represents spending some £178Bn on defence equipment and support over that period.  In 2015/16 MOD spent nearly £20Bn with industry, accounting for over 40% of all UK government procurement spend and representing the fifth biggest defence budget in the world.

The size and complexity of many of our projects mean that we need to work closely with our most important suppliers to ensure delivery of the Defence programme.  These are currently Boeing, BAe Systems, Rolls-Royce, Airbus, Lockheed Martin, Thales, QinetiQ, Leonardo, MBDA, Babcock, Serco, Capita, AWE and HP.

We advocate the use of competition wherever appropriate both in our direct contact opportunities and throughout the supply chain.  Opportunities, therefore, exist for suppliers of all sizes, from largely established defence contractors through to innovative smaller businesses, to get involved in our procurement activity both as a prime supplier and as a sub-contractor.

The programmes we support are detailed in the Defence Equipment Plan; the top three equipment programmes in terms of spend include Typhoon, Future Strategic Tanker Aircraft and Astute Attack Submarine.  In addition, we spend over £3Bn annually on infrastructure and defence estates.
