On 2 and 3 November 2026, Germany and the United Kingdom reaffirmed their intention to significantly deepen bilateral military and security cooperation. A joint ministerial declaration and work programme provides for systematic progress on joint projects in capability development, stronger cooperation on cyber and sabotage defence, and coordinated research projects, including on artificial intelligence in defence systems. The announcements build on previous agreements and cooperation frameworks, notably the Trinity House Agreement signed in October 2024 and the action plan agreed in July 2025 to implement the treaty of friendship and cooperation between the two countries. (Valid publication dates: 2 November 2026; references to visits and agreements from 8 October 2026 and earlier.)
According to the governments, the current agreements focus on closing capability gaps within Europe and strengthening deterrence on NATOflanks. Specific measures mentioned include joint trials, coordinated procurement initiatives and a planned German-British round table in spring 2027, which is intended to bring together government, industry and research. Bilateral cooperation on countering hybrid threats, particularly acts of sabotage and cyberattacks, is also to be intensified. The two countries say they are responding in this way to the growing complexity of security risks in Europe.
The decisions follow government-level talks: the British Prime Minister’s visit to Berlin on 8 October 2026 had already included a series of strategic declarations of intent, including the expansion of cooperation in space, defence technology and migration. Defence Minister and senior military representatives from both sides stressed that the new steps are intended to make the two armed forces more interoperable while strengthening Europe’s role within NATO.
Implications and open questions: The agreements are shifting cooperation further into technological fields such as AI and cyber defence, which is likely to reignite debate about export controls, parliamentary oversight and the boundaries between civilian and military use. The published statements have so far given only general information on funding issues and specific timelines for procurement projects; details are to be worked out in subsequent ministerial forums and bilateral working groups. Differences within Europe, for example with partners pursuing their own procurement programmes, could prove challenging in practice.
The reports were checked against official statements from the of the Federal Government, published on the same day. They show both increased participation in the and the British Ministry of Defence; both sides have announced further detailed dates for upcoming working sessions.
