This page provides the background and the political and organisational context from which OPLAN DEU emerged – from the wider context to the legal basis, commentary and original sources.
Context
Operation Plan Germany (OPLAN DEU)does not stand in isolation; it is the result of profound security policy and structural developments in recent years. Here you will find the wider framework for understanding its significance:
NATO’s change of strategy: back to collective defence
After years of crisis intervention in distant areas of operation, NATO made a clear change of course following Russia’s annexation of Crimea in 2014 and its attack on Ukraine in 2022: the focus is once again on the collective defence of Alliance territory. Germany plays a central role as a logistics hub in Central Europe. OPLAN DEU is the national implementation document for these multinational plans.
Zeitenwende & whole-of-government realignment
Since thegovernment statementof 27 February 2022 (“Zeitenwende”), Germany has been building a robust security architecture: a €100 billion special fund for the Bundeswehr, raising the defence budget above 2% of GDP and a return to territorial defence planning. OPLAN DEU emerged directly from this political change of course.
Bundeswehr structure and planning authority
OPLAN DEU is planned and coordinated by the Bundeswehr Joint Operations Command (OpFüKdoBw). It is responsible for planning, command and coordination with other ministries, the federal states and civilian partners.
Whole-of-government defence in Germany
Germany’s defence architecture is designed on a whole-of-government basis: in addition to military forces, federal ministries, state authorities, local authorities and private actors are involved – especially from logistics, energy and critical infrastructure. Challenges arise from federal responsibilities, a lack of exercise culture and information asymmetries. OPLAN DEU serves to make these fragmented structures able to act through clear processes and responsibilities.
The role of OPLAN DEU as a national link
OPLAN DEU connects NATO planning, Bundeswehr command and civilian support. It sets out how and where troops are deployed, which infrastructure is used and which civilian actors are involved, for example for Host Nation Support and the transport of allied forces to NATO’s eastern flank. It thus puts Germany’s whole-of-government approach to defence into practice.
Germany’s importance as a NATO hub
NATO regards Germany strategically as a central hub for transporting and supporting troops. OPLAN DEU specifies Germany’s role as Host Nation – including provisions on transport routes, protection of critical infrastructure and logistical capacity at home.
Legal basis
The state of defence in the Basic Law: legal framework, effect and limits
The Basic Law (Grundgesetz) explicitly provides for the state of defence as the most extreme level of state emergency. It is governed by Articles 115a to 115l and is regarded as the “emergency generator” for preserving the free democratic basic order in the event of an attack on federal territory from outside.
Definition and triggering
A state of defence is determined if federal territoryis attacked by armed force or such an attack is imminent. The determination requires a qualified majority in the Bundestag (two-thirds majority) and, if the Bundestag cannot decide quickly, theJoint Committeecan act in the meantime.
Strengthening the executive, protecting democracy
When a state of defence is declared, the balance of power shifts: the executive receives extended powers so that it can act quickly under conditions of great urgency.
A central mechanism is that, when the state of defence is promulgated, supreme power of command over the armed forces automatically passes to the Federal Chancellor (Art. 115b).
Legislative and administrative tasks are also concentrated at federal level in order to streamline administrative processes (Art. 115c).
Despite this shift in power, democratic control structures remain in place: the Bundestag retains important rights of information and scrutiny, can end the state of defence and must be informed “without delay” of all special measures (Art. 115f). The Federal Constitutional Court also remains competent and can review acts of the executive.
Restrictions and limits
Even in a state of defence, restrictions apply to interference with fundamental rights: modifications are only permitted where they are proportionate (e.g. provisional arrests, compensation for expropriation).
The state of defence is not intended to be declared for every terrorist or digital attack, but only if the existence of the state or its order were threatened.
What happens if no two-thirds majority for the state of defence is found in the Bundestag?
What happens if no two-thirds majority for the state of defence is found in the Bundestag?
If the Bundestag cannot meet in time in a crisis, or a two-thirds majority fails because of political deadlock,Article 115a(4) of the Basic Lawapplies: if Germany is actually attacked from outside, the provisions on the state of defence enter into force automatically – even without prior formal determination by the Bundestag and Bundesrat. The Basic Law thus ensures that the state’s ability to act is maintained even in the event of political deadlock.
Criticism and relevance today
While Article 115a originated in an East–West context, there is debate about whether its criteria still fit today’s threat picture of cyberattacks, hybrid threats and asymmetric violence. Some therefore regard the provision as outdated. Attempts to modernise emergency powers have so far been limited, partly because of political concerns about shifts in power or public resistance.
Commentary
Commentary & opinions on OPLAN
BAKS working paper
In the BAKS working paper “Noch nicht Krieg, aber auch nicht Frieden” (“Not yet war, but not peace either”), Philipp Lange calls for Germany to significantly strengthen its national capacity for defence and its resilience – because hybrid attacks and subtle influence campaigns already have the effect of war, even before firearms are used.
Commentary by the Reservists’ Association
The logistical implementation of OPLAN DEU is currently hampered by a lack of standards, unclear responsibilities and insufficient civilian involvement. There are gaps particularly in infrastructure, staff, transhipment hubs and contractual arrangements that could jeopardise Germany’s ability to function as a logistics hub in an emergency.

The Bundeswehr’s OPLAN
This document from the Joint Operations Command provides an official introduction to Operation Plan Germany (OPLAN DEU), describes its origins, objectives and the link between military and civilian support tasks, and shows how procedures, processes and responsibilities are brought together in an operationally executable plan.

Bundeswehr Joint Operations Command
The official website of the Joint Operations Command explains the scope, objectives and tasks of OPLAN DEU, including the operational integration of military and civilian components, the coordination of support services and the command’s leading role in crisis and defence scenarios.
Framework Guidelines for Total Defence
The Framework Guidelines for Total Defence (RRGV) of 5 June 2024 set out the cross-ministry principles for how Germany remains able to act in a state of tension or defence. They coordinate military and civilian measures and thus form the strategic basis for OPLAN DEU in the civilian sphere.
The aim of the RRGV is to ensure Germany’s ability to function and act under crisis conditions, through both military and civilian means. They emphasise close interlinking between the Bundeswehr, federal and state authorities, business and the population. The RRGV replace the 1989 version and have been adapted to current threats (e.g. hybrid attacks, critical infrastructure, cyber operations).
State of defence in the Basic Law
In Articles 115a to 115l , the Basic Law governs the state of defence as the most extreme emergency: if Germany is attacked by armed force or such an attack is imminent, special constitutional mechanisms come into force. When the state of defence is declared, power of command passes to the Federal Chancellor (Art. 115b), legislative and administrative powers can be concentrated at federal level (Art. 115c), but parliament and the Constitutional Court retain rights of scrutiny and participation (Art. 115f, 115g).
