UK Germany Defence Ministerial Council Joint Statement

At their second Defence Ministerial Council, the United Kingdom and Germany agreed to keep expanding joint defence work. Their shared aim is to strengthen Europe’s contribution to NATO, improve deterrence and help provide the forces needed for collective defence. They also reaffirmed unwavering support for Ukraine and its Armed Forces.

The agreement covers several practical projects. The countries are developing Deep Precision Strike capabilities with ranges over 2,000 kilometres. They are improving land-force readiness, maritime cooperation and air-force coordination. Germany’s P-8A Poseidon aircraft have already operated from the UK during exercises. Defence officials also agreed to add artificial intelligence to the Cyber Lighthouse Project and explore cooperation in space.

The partnership is moving from promises toward delivery. The UK and Germany signed an arrangement on Sting Ray procurement and began work on defence-space cooperation. Their teams must maintain momentum through 2027, focusing on tangible outcomes, stronger interoperability and support for Ukraine’s security.

The Trinity House Agreement is a framework for organising defence cooperation between the United Kingdom and Germany. It links their governments, armed forces, capability teams and industries around a common security purpose. The agreement supports a stronger European contribution to NATO, greater deterrence and improved collective defence. The Kensington Treaty reinforces this framework.

The agreement works through ministerial direction and practical cooperation. Projects cover land forces, maritime procurement, air operations, cyber and artificial intelligence, space and long-range strike. For example, the two countries are developing Deep Precision Strike capabilities and expanding the Cyber Lighthouse Project. Their forces also train together, while German P-8A aircraft use UK facilities on an episodic basis.

The arrangement is designed to keep evolving. The second council directed teams to maintain momentum through 2027, with an emphasis on delivery and tangible results. Its value is therefore not only political: it connects strategy with exercises, procurement, research, industry and operational readiness.

The article identifies Deep Precision Strike as the largest quantified military project. The capability is being developed jointly by the United Kingdom and Germany, with ranges over 2,000 kilometres. The governments describe it as a landmark project because it would give them a long-range precision capability while strengthening their industrial cooperation.

The project is not presented as a finished weapon. It is under development, with delivery planned within the decade. The programme also involves supply chains in UK and German industry, so its effect extends beyond armed forces. Other projects are substantial but have no stated size in the article. They include Sting Ray procurement, P-8A maritime cooperation, future uncrewed systems and expanded cyber, artificial-intelligence and space work.

The current reality is significant progress rather than completion. The statement gives no unit numbers, cost or exact delivery date. It does show a broad portfolio, with Deep Precision Strike providing the clearest scale marker and the two governments directing teams to produce tangible outcomes through 2027.

The Ukraine Defence Contact Group is supported by the United Kingdom, Germany, Ukraine and their international partners. The UK and Germany are its co-chairs. The group’s purpose is to help ensure that Ukraine’s Armed Forces receive the support required while resisting Russia’s illegal invasion. It also provides a structure for partners to work together.

Its key mechanism is matching requirements with capabilities. The countries agreed to keep developing the group so that Ukraine’s needs are more directly linked to what partners can supply. This makes coordination the central task. The statement does not list every participating country or every type of equipment, so those details cannot be identified from the text.

The group remains part of a wider political effort. The UK and Germany will continue supporting Ukraine and working with the Coalition of the Willing on robust, credible security guarantees. Those guarantees are intended for implementation after hostilities cease, when conditions are right, and should support a just and lasting peace.

Interoperability means forces can work together effectively. The statement connects stronger interoperability between British and German forces with Europe’s ability to deter threats and defend itself. This matters because the UK and Germany describe their security as inseparable from Europe’s security. Their cooperation is therefore presented as part of a wider continental effort, not simply a bilateral relationship.

The mechanism is practical cooperation. The countries are strengthening land-force readiness, training maritime forces together and developing air cooperation through a bilateral Flight Plan. German P-8A aircraft have operated from the UK during exercises, including Dynamic Mongoose and Strike Warrior. Shared work on future uncrewed systems, strike capabilities and other technologies can also improve coordination.

The stated consequence is a stronger Europe within a stronger NATO. The article does not claim that cooperation removes every threat. It says the partnership can reinforce deterrence and help Europe provide the capabilities and forces required for collective defence, while keeping the continent safer.

The article presents cooperation as a way to build stronger capabilities together. The UK and Germany want forces that can operate more effectively with one another, industries that can support shared projects and technologies that answer common military needs. Working together also supports Europe’s contribution to NATO and helps the countries strengthen deterrence. The statement does not claim that every project must be combined.

Examples show how this works. Deep Precision Strike joins development with UK and German supply chains. The Cyber Lighthouse Project will test shared military artificial-intelligence use cases. German P-8A aircraft use UK support during exercises, while defence ministries are exploring cooperation on satellite communications, earth observation, data exploitation and space-domain awareness.

This approach is already producing activity rather than remaining theoretical. An Implementing Arrangement was signed for Sting Ray procurement, exercises have taken place and the AI and space work is beginning. The two governments directed their teams to continue through 2027, focusing on delivery, capability development and adoption.

NATO is an alliance built around the principle that its members contribute to one another’s collective defence. The article does not define NATO in detail, but it states that European security depends on strengthening Europe’s contribution to the alliance. In this context, stronger national forces and closer cooperation support the wider defence of Europe.

The mechanism is shared capability. The UK and Germany are improving readiness and interoperability, developing long-range precision strike, conducting maritime exercises and expanding air, cyber, artificial-intelligence and space cooperation. These activities can help European countries provide forces and capabilities that work together. The article specifically links this effort to reinforcing deterrence and meeting collective-defence requirements.

The stated direction is “a stronger Europe in a stronger NATO.” The partnership is not described as replacing NATO. Instead, it is a bilateral way to build European capacity within the alliance. Continued work through 2027 should focus on delivery, tangible outcomes and sustained support for Ukraine.
