The EU command and control structures are much smaller than the North Atlantic Treaty Organization's (NATO) Command Structure (NCS), which has been established for territorial defence. It has been agreed that NATO's Allied Command Operations (ACO) may be used for the conduct of the EU's missions. The MPCC, established in 2017 and to be strengthened in 2020, is the EU's first permanent military OHQ. In parallel, the newly established European Defence Fund (EDF) marks the first time the EU budget is used to finance multinational defence projects.
Decisions relating to the CSDP are proposed by the High Representative, adopted by the Foreign Affairs Council, generally requiring unanimity, to be then implemented by the High Representative.
Organigramme for the European Defence Community (EDC), which – if ratified – would have created a unified defence arm for the later to be established European Political Community (EPC). This force would represent an autonomous European pillar within NATO, under the authority of the Supreme Commander.
Time illustration of divisions planned for the EDC, which in 1954 failed to acquire French ratification.
In 1970 the European Political Cooperation (EPC) brought about the European Communities' (EC) initial foreign policy coordination. Opposition to the addition of security and defence matters to the EPC led to the reactivation of the WEU in 1984 by its member states, which were also EC member states.
European defence integration gained momentum soon after the end of the Cold War, partly as a result of the EC's failure to prevent the Yugoslav Wars. In 1992, the WEU was given new tasks, and the following year the Treaty of Maastricht founded the EU and replaced the EPC with the Common Foreign and Security Policy (CFSP) pillar. In 1996 NATO agreed to let the WEU develop a so-called European Security and Defence Identity (ESDI).[7] The 1998 St. Malo declaration signalled that the traditionally hesitant United Kingdom was prepared to provide the EU with autonomous defence structures.[8] This facilitated the transformation of the ESDI into the European Security and Defence Policy (ESDP) in 1999, when it was transferred to the EU. In 2003 the EU deployed its first CSDP missions, and adopted the European Security Strategy identifying common threats and objectives. In 2009, the Treaty of Lisbon introduced the present name, CSDP, while establishing the EEAS, the mutual defence clause and enabling a subset of member states to pursue defence integration within PESCO. In 2011 the WEU, whose tasks had been transferred to the EU, was dissolved. In 2016 a new security strategy was introduced, which along with the Russian annexation of Crimea, the British withdrawal from the EU and the election of Trump as US president have given the CSDP a new impetus.
Since the end of World War II, sovereignEuropean countries have entered into treaties and thereby co-operated and harmonised policies (or pooled sovereignty) in an increasing number of areas, in the European integration project or the construction of Europe (French: la construction européenne). The following timeline outlines the legal inception of the European Union (EU)—the principal framework for this unification. The EU inherited many of its present responsibilities from the European Communities (EC), which were founded in the 1950s in the spirit of the Schuman Declaration.
Legend: S: signing F: entry into force T: termination E: expiry de facto supersession Rel. w/ EC/EU framework: de facto inside outside
^ abcdeAlthough not EU treaties per se, these treaties affected the development of the EU defence arm, a main part of the CFSP. The Franco-British alliance established by the Dunkirk Treaty was de facto superseded by WU. The CFSP pillar was bolstered by some of the security structures that had been established within the remit of the 1955 Modified Brussels Treaty (MBT). The Brussels Treaty was terminated in 2011, consequently dissolving the WEU, as the mutual defence clause that the Lisbon Treaty provided for EU was considered to render the WEU superfluous. The EU thus de facto superseded the WEU.
^Between the EU's founding in 1993 and consolidation in 2009, the union consisted of three pillars, the first of which were the European Communities. The other two pillars consisted of additional areas of cooperation that had been added to the EU's remit.
Since 2002, the European Union has intervened abroad thirty-five times in three different continents.
The first deployment of European troops under the ESDP, following the 1999 declaration of intent, was in March 2003 in the former Yugoslav Republic of Macedonia (FYROM, today: North Macedonia). Operation Concordia used NATO assets and was considered a success and replaced by a smaller police mission, EUPOL Proxima, later that year. Since then, there have been other small police, justice and monitoring missions. As well as in the FYROM, the EU has maintained its deployment of peacekeepers in Bosnia and Herzegovina, as part of Operation Althea.[9]
Between May and September 2003 EU troops were deployed to the Democratic Republic of the Congo (DRC) during "Operation Artemis" under a mandate given by UN Security Council Resolution 1484 which aimed to prevent further atrocities and violence in the Ituri Conflict and put the DRC's peace process back on track. This laid out the "framework nation" system to be used in future deployments. The EU returned to the DRC during July–November 2006 with EUFOR RD Congo, which supported the UN mission there during the country's elections.
Geographically, EU missions outside the Balkans and the DRC have taken place in Georgia, Indonesia, Sudan, Palestine, and Ukraine–Moldova. There is also a judicial mission in Iraq (EUJUST Lex). On 28 January 2008, the EU deployed its largest and most multi-national mission to Africa, EUFOR Tchad/RCA.[10] The UN-mandated mission involves troops from 25 EU states (19 in the field) deployed in areas of eastern Chad and the north-eastern Central African Republic in order to improve security in those regions. EUFOR Tchad/RCA reached full operation capability in mid-September 2008, and handed over security duties to the UN (MINURCAT mission) in mid-March 2009.[11]
The EU launched its first maritime CSDP operation on 12 December 2008 (Operation Atalanta). The concept of the European Union Naval Force (EU NAVFOR) was created on the back of this operation, which is still successfully combatting piracy off the coast of Somalia almost a decade later. A second such intervention was launched in 2015 to tackle migration problems in the southern Mediterranean (EUNAVFOR Med), working under the name Operation SOPHIA.
Most of the CSDP missions deployed so far are mandated to support security sector reforms (SSR) in host-states. One of the core principles of CSDP support to SSR is local ownership. The EU Council defines ownership as "the appropriation by the local authorities of the commonly agreed objectives and principles".[12] Despite EU's strong rhetorical attachment to the local ownership principle, research shows that CSDP missions continue to be an externally driven, top-down and supply-driven endeavour, resulting often in the low degree of local participation.[13]
While the EU has a command and control (C2) structure, it has no standing permanent military structure along the lines of the North Atlantic Treaty Organization's (NATO) Allied Command Operations (ACO), although it has been agreed that ACO resources may be used for the conduct of the EU's CSDP missions. The MPCC, established in 2017 and to be strengthened in 2020, does however represent the EU's first step in developing a permanent military headquarters. In parallel, the newly established European Defence Fund (EDF) marks the first time the EU budget is used to finance multinational defence projects. The CSDP structure is sometimes referred to as the European Defence Union (EDU), especially in relation to its prospective development as the EU's defence arm.[4][5][6][c]
Decisions relating to the CSDP are proposed by the HR/VP, adopted by the FAC, generally requiring unanimity, and then implemented by the HR/VP.
The EU command and control (C2) structure is directed by political bodies composed of member states' representatives, and generally requires unanimous decisions. As of April 2019:[14]
Liaison: Advice and recommendations Support and monitoring Preparatory work
1 In the event of a CSDP Civilian Mission also being in the field, the relations with the Civilian Planning and Conduct Capability (CPCC) and its Civilian Operation Commander (Civ OpCdr), as well as the subordinate Head of Mission (HoM), are coordinated as shown.
2 Other Component Commanders (CCs) and service branches which may be established.
3 The MPCC is part of the EUMS and Dir MPCC is double-hatted as DGEUMS. Unless the MPCC is used as Operation Headquarters (OHQ), either a national OHQ offered by member states or the NATO Command Structure (NCS) would serve this purpose. In the latter instance, Deputy Supreme Allied Commander Europe (DSACEUR), rather than Dir MPCC, would serve as Operation Commander (OpCdr).
4 Unless the MPCC is used as Operation Headquarters (OHQ), the MFCdr would be known as a Force Commander (FCdr), and direct a Force Headquarters (FHQ) rather than a MFHQ. Whereas the MFHQ would act both on the operational and tactical level, the FHQ would act purely on the operational level.
5 The political strategic level is not part of the C2 structure per se, but represents the political bodies, with associated support facilities, that determine the missions' general direction. The Council determines the role of the High Representative (HR/VP), who serves as Vice-President of the European Commission, attends European Council meetings, chairs the Foreign Affairs Council (FAC) and may chair the Political and Security Committee (PSC) in times of crisis. The HR/VP proposes and implements CSDP decisions.
The European Union Global Strategy (EUGS) is the updated doctrine of the EU to improve the effectiveness of the CSDP, including the defence and security of the members states, the protection of civilians, cooperation between the member states' armed forces, management of immigration, crises etc. Adopted on 28 June 2016,[15] it replaces the European Security Strategy of 2003. The EUGS is complemented by a document titled "Implementation Plan on Security and Defense" (IPSD).[16]
Five EU states host nuclear weapons: France has its own nuclear programmes, while Belgium, Germany, Italy and the Netherlands host US nuclear weapons as part of NATO's nuclear sharing policy. Combined, the EU possesses 300 warheads, and hosts between 90 and 130 US warheads. Italy hosts 70-90 B61 nuclear bombs, while Germany, Belgium, and the Netherlands 10-20 each one.[19] The EU has the third largest arsenal of nuclear weapons, after the United States and Russia.
The following table presents the military expenditures of the members of the European Union in euros (€). The combined military expenditure of the member states amounted to €223.4 billion in 2018.[2] This represents 1.4% of European Union GDP. European military expenditure includes spending on joint projects such as the Eurofighter Typhoon and joint procurement of equipment. The European Union's combined active military forces in 2016 totaled 1,410,626 personnel.[1]
In a speech in 2012, Swedish General Håkan Syrén criticised the spending levels of European Union countries, saying that in the future those countries' military capability will decrease, creating "critical shortfalls".[20]

Charles de Gaulle aircraft carrier is one of the largest commissioned warships in the European Union.
The combined component strength of the naval forces of member states is some 514 commissioned warships. Of those in service, 4 are fleet carriers. The EU also has 4 amphibious assault ships and 20 amphibious support ships in service. Of the EU's 49 submarines, 10 are nuclear-powered submarines while 39 are conventional attack submarines.
Operation Atalanta (formally European Union Naval Force Somalia) is the first ever (and still ongoing) naval operation of the European Union. It is part of a larger global action by the EU in the Horn of Africa to deal with the Somali crisis. As of January 2011 twenty-three EU nations participate in the operation.
Combined, the member states of the European Union maintain large numbers of various land-based military vehicles and weaponry.

The air forces of EU member states operate a wide range of military systems and hardware. This is primarily due to the independent requirements of each member state and also the national defence industries of some member states. However such programmes like the Eurofighter Typhoon and Eurocopter Tiger have seen many European nations design, build and operate a single weapons platform. 60% of overall combat fleet was developed and manufactured by member states, 32% are US-origin, but some of these were assembled in Europe, while remaining 8% are soviet-made aircraft. As of 2014, it is estimated that the European Union had around 2,000 serviceable combat aircraft (fighter aircraft and ground-attack aircraft).[45]
The EUs air-lift capabilities are evolving with the future introduction of the Airbus A400M (another example of EU defence cooperation). The A400M is a tactical airlifter with strategic capabilities.[46] Around 140 are initially expected to be operated by 5 member states (Luxembourg, France, Germany, Spain and Belgium).
Guide to tables:
The tables are sourced from figures provided by Flight International for the year 2020.
Aircraft are grouped into three main types (indicated by colours): red for combat aircraft, green for aerial refueling aircraft, and grey for strategic and tactical transport aircraft.
The two "other" columns include additional aircraft according to their type sorted by colour (i.e. the "other" category in red includes combat aircraft, while the "other" category in grey includes both aerial refueling and transport aircraft). This was done because it was not feasible allocate every aircraft type its own column.
Other aircraft such as trainers, helicopters, UAVs and reconnaissance or surveillance aircraft are not included in the below tables or figures.
The Helsinki Headline Goal Catalogue is a listing of rapid reaction forces composed of 60,000 troops managed by the European Union, but under control of the countries who deliver troops for it.
Forces introduced at Union level include:
The battle groups (BG) adhere to the CSDP, and are based on contributions from a coalition of member states. Each of the eighteen Battlegroups consists of a battalion-sized force (1,500 troops) reinforced with combat support elements.[50][51] The groups rotate actively, so that two are ready for deployment at all times. The forces are under the direct control of the Council of the European Union. The Battlegroups reached full operational capacity on 1 January 2007, although, as of January 2013 they are yet to see any military action.[52] They are based on existing ad hoc missions that the European Union (EU) has undertaken and has been described by some as a new "standing army" for Europe.[51] The troops and equipment are drawn from the EU member states under a "lead nation". In 2004, United Nations Secretary-General Kofi Annan welcomed the plans and emphasised the value and importance of the Battlegroups in helping the UN deal with troublespots.[53]
The Medical Command (EMC) is a planned medical command centre in support of EU missions, formed as part of the Permanent Structured Cooperation (PESCO).[54] The EMC will provide the EU with a permanent medical capability to support operations abroad, including medical resources and a rapidly deployable medical task force. The EMC will also provide medical evacuation facilities, triage and resuscitation, treatment and holding of patients until they can be returned to duty, and emergency dental treatment. It will also contribute to harmonising medical standards, certification and legal (civil) framework conditions.[55]
The Force Crisis Response Operation Core (EUFOR CROC) is a flagship defence project under development as part of Permanent Structured Cooperation (PESCO). EURFOR CROC will contribute to the creation of a "full spectrum force package" to speed up provision of military forces and the EU's crisis management capabilities.[56] Rather than creating a standing force, the project involves creating a concrete catalogue of military force elements that would speed up the establishment of a force when the EU decides to launch an operation. It is land-focused and aims to generate a force of 60,000 troops from the contributing states alone. While it does not establish any form of "European army", it foresees an deployable, interoperable force under a single command.[57] Germany is the lead country for the project, but the French are heavily involved and it is tied to President Emmanuel Macron's proposal to create a standing intervention force. The French see it as an example of what PESCO is about.[58]

This section presents an incomplete list of forces and bodies established intergovernmentally amongst a subset of member states. These organisations will deploy forces based on the collective agreement of their member states. They are typically technically listed as being able to be deployed under the auspices of NATO, the United Nations, the European Union (EU) through Article 42.3 of TEU, the Organization for Security and Co-operation in Europe, or any other international entity.
However, with the exception of the Eurocorps, very few have actually been deployed for any real military operation, and none under the CSDP at any point in its history.
The European Gendarmerie Force, an intervention force with militarised police functions which specializes in crisis management.[60]
Aerial:
The European Air Transport Command exercises operational control of the majority of the aerial refueling capabilities and military transport fleets of its participating nations. Located at Eindhoven Airbase in the Netherlands, the command also bears a limited responsibility for exercises, aircrew training and the harmonisation of relevant national air transport regulations.[61][62] The command was established in 2010 to provide a more efficient management of the participating nations' assets and resources in this field.
Out of the 27 EU member states, 22 are also members of NATO. Another four NATO members are EU applicants—Albania, Montenegro, North Macedonia and Turkey. Two others—Iceland and Norway—have opted to remain outside of the EU, however participate in the EU's single market. The memberships of the EU and NATO are distinct, and some EU member states are traditionally neutral on defence issues. Several EU member states were formerly members of the Warsaw Pact. Denmark had an opt-out from the CSDP,[1] however voted in a referendum in 2022 to begin to participate in the policy area.

"If a Member State is the victim of armed aggression on its territory, the other Member States shall have towards it an obligation of aid and assistance by all the means in their power, in accordance with Article 51 of the United Nations Charter. This shall not prejudice the specific character of the security and defence policy of certain Member States. [...]"
"The Parties agree that an armed attack against one or more of them [on their territory] shall be considered an attack against them all and consequently they agree that, if such an armed attack occurs, each of them, in exercise of the right of individual or collective self-defence recognised by Article 51 of the Charter of the United Nations, will assist the Party or Parties so attacked by taking forthwith, individually and in concert with the other Parties, such action as it deems necessary, including the use of armed force, to restore and maintain the security of the North Atlantic area. [...]"
The Berlin Plus agreement is the short title of a comprehensive package of agreements made between NATO and the EU on 16 December 2002.[66] These agreements were based on conclusions of NATO's 1999 Washington summit, sometimes referred to as the CJTF mechanism,[67] and allowed the EU to draw on some of NATO's military assets in its own peacekeeping operations.

Organisation for Joint Armament Cooperation (OCCAR), an organisation that facilitates and manages collaborative armament programmes through their lifecycle between its participating nations.
European Air Group (EAG), an organisation that promotes cooperation and interoperability between the air forces of its participating nations.
Movement Coordination Centre Europe (MCCE), an organisation aiming to coordinate the use of airlift, sealift and land movement assets owned or leased by participating nations.
Notes
^ abThe responsibility of collective self-defence within the CSDP is based on Article 42.7 of TEU, which states that this responsibility does not prejudice the specific character of the security and defence policy of certain member states, referring to policies of neutrality. See Neutral country§European Union for discussion on this subject.According to the Article 42.7 "If a Member State is the victim of armed aggression on its territory, the other Member States shall have towards it an obligation of aid and assistance by all the means in their power, in accordance with Article 51 of the United Nations Charter. This shall not prejudice the specific character of the security and defence policy of certain Member States."
Article 42.2 furthermore specifies that NATO shall be the main forum for the implementation of collective self-defence for EU member states that are also NATO members.
