The National Security Strategy and Strategic Defence and Security Review 2015 was published by the British government during the second Cameron ministry on 23 November 2015 to outline the United Kingdom's defence strategy up to 2025. It identified key threats to the UK and the capabilities it required to address them. [1]
The National Security Risk Assessment 2015 found the threats faced by the UK, including its Overseas Territories and overseas interests, have "increased in scale, diversity and complexity" since 2010. It highlighted four particular threats that are likely to be priorities for UK security in the coming decade: [2] : 15
The commitments in the paper for equipment and support for the three services amounted to £178 billion up to 2025. This is roughly 20% of the 10 year budget period. [3]
The government reaffirmed its commitment to spending 2% of national GDP on defence. [2] : 27
The government outlined a range of foreign policy initiatives. These included:
The Royal Air Force (RAF) is the air and space force of the United Kingdom, British Overseas Territories and Crown Dependencies. It was formed towards the end of the First World War on 1 April 1918, becoming the second independent air force in the world after the Finnish Air Force merging the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has played a significant role in British military history. In particular, during the Second World War, the RAF established air superiority over Hermann Göring's Luftwaffe during the Battle of Britain, and led the Allied strategic bombing effort.
The Royal Navy (RN) is the naval warfare force of the United Kingdom, British Overseas Territories and Crown Dependencies, and a component of His Majesty's Naval Service. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.
The Eurofighter Typhoon is a European multinational twin-engine, supersonic, canard delta wing, multirole fighter. The Typhoon was designed originally as an air-superiority fighter and is manufactured by a consortium of Airbus, BAE Systems and Leonardo that conducts the majority of the project through a joint holding company, Eurofighter Jagdflugzeug GmbH. The NATO Eurofighter and Tornado Management Agency, representing the UK, Germany, Italy and Spain, manages the project and is the prime customer.
The Raytheon Sentinel is a retired airborne battlefield and ground surveillance aircraft formerly operated by the Royal Air Force (RAF). While based on the Bombardier Global Express ultra long-range business jet, the prime contractor for the Sentinel was the American defence firm Raytheon, which supplied most of the mission systems and performed the integration work.
Future planning of the Royal Navy's capabilities is set through periodic Defence Reviews carried out by the British Government.
The Strategic Defence Review (SDR) was a British policy document produced in July 1998 by the Labour Government that had gained power a year previously. Then Secretary of State for Defence, George Robertson, set out the initial defence policy of the new government, with a series of key decisions designed to enhance the United Kingdom's armed forces.
The 2003 Defence White Paper, titled Delivering Security in a Changing World, set out the future structure of the British military, and was preceded by the 1998 Strategic Defence Review (SDR) and the 2002 SDR New Chapter, which responded to the immediate challenges to security in the aftermath of the September 11 attacks in 2001. Published under the then Secretary of State for Defence, Geoff Hoon, the report effectively introduced a series of cutbacks to core equipment and manpower and the scaling back of a series of future capital procurement projects. This was justified due to the implementation of a policy termed Network Enabled Capability. The review also outlined a major restructuring and consolidation of British Army Infantry regiments.
The Eurofighter Typhoon is in service with nine nations: United Kingdom, Germany, Italy, Spain, Saudi Arabia, Oman, Qatar, Kuwait, and Austria, with orders for all nine customers still pending as of September 2017. The aircraft has, as of 2016, been provided in a basic air-defense form and has been upgraded to newer production standards which include internal IRST, air-to-ground precision strike capability, and HMSS helmets. Most of the major systems including the CAPTOR radar and the Defence Aids Sub-System (DASS) are expected to be improved and updated over time, with the radar being updated to an AESA, being the CAPTOR-E/CAESAR, of which the Kuwait Air Force will be the inaugural operator, with first deliveries of their 28 new-built aircraft to commence in 2019.
The Joint Combat Aircraft (JCA) is the official designation of the United Kingdom Ministry of Defence used for the F-35 Lightning II. The F-35, developed from the X-35, is the result of the Joint Strike Fighter program.
The Japan Maritime Self-Defense Force, abbreviated JMSDF, also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships, 346 aircraft and 50,800 personnel.
The history of the Royal Air Force, the air force of the United Kingdom, spans a century of British military aviation.
The Royal Australian Navy, although a significant force in the Asia-Pacific region, is nonetheless classed as a medium-sized navy. Its fleet is based around two main types of surface combatant, with limited global deployment and air power capability. However, in 2009, a white paper, Defending Australia in the Asia Pacific Century: Force 2030, was produced by the Australian government which set out a programme of defence spending that will see significant improvements to the RAN's fleet and capabilities. In recent times, Australia released its Surface Fleet Review in 2024, which analyses the future of the RAN and shows what the Government will procure.
Defence Equipment and Support (DE&S) is a trading entity and joint-defence organisation within the UK Ministry of Defence. It began operating on 2 April 2007, following the merger of the MoD's Defence Procurement Agency and the Defence Logistics Organisation, under the Chief Executive Officer of Defence Equipment and Support.
The planning for the future of the Royal Air Force involves supporting ongoing British military operations and the introduction of new aircraft types including unmanned aerial vehicles and the BAE Systems Tempest sixth-generation fighter in the 2030s. Priorities include greater focus on network enabled capability and mixing crewed fighter jets with UAVs and swarming drones. The new initiative will focus on increasing interoperability with members of NATO and becoming carbon net-zero, with strategies such as using sustainable aviation fuels in aircraft.
Army 2020 Refine was the name given to the restructuring of the British Army in the mid-to-late 2010s, in light of the Strategic Defence and Security Review 2015. As its name suggests, it was a "refinement" of Army 2020, an early 2010s reorganisation of the Army to be completed by 2020, originally conducted in light of the Strategic Defence and Security Review 2010.
The Strategic Defence and Security Review 2010 was announced by the formed Conservative-Liberal Democrat coalition government of the United Kingdom in May 2010, and published on 19 October 2010. The previous major review of UK defence strategy was the Strategic Defence Review, published in 1998, and updated in 2003 by the Delivering Security in a Changing World white paper.
The 1981 Defence White Paper was a major review of the United Kingdom's defence policy brought about by the Conservative government under the Prime Minister Margaret Thatcher. The main author was the then Secretary of State for Defence, John Nott. The aim of the review was to reduce expenditure during the early 1980s recession and to focus on supporting NATO rather than out of area operations. It was ultimately judged however to have been extremely detrimental to the United Kingdom's defence posture, being one of the contributing factors that led to the outbreak of the Falklands War.
The Integrated Review of Security, Defence, Development and Foreign Policy, often known as the Integrated Review, and titled as Global Britain in a Competitive Age, was a review carried out by the British government led by Boris Johnson into the foreign, defence, security and international development policies of the United Kingdom. Described by Johnson as "the largest review of its kind since the Cold War", the review was published on 16 March 2021.
Defence in a Competitive Age is a Ministry of Defence command paper which was released on 22 March 2021. It provided details on changes to the armed forces to meet the requirements of the Integrated Review which was published before it on 16 March 2021.
