UK Defence Secretary Wes Streeting and German Defence Minister Boris Pistorius held the second Defence Ministerial Council under the Trinity House Agreement in Berlin on 2 November and announced in a joint statement that the agreement's Cyber Lighthouse Project would be expanded to incorporate artificial intelligence. Through 'collaboration on a small number of shared military use cases,' the two countries will deepen cooperation in capability development, experimentation and adoption. No systems or budgets were named; government and industry representatives will meet in spring 2027 to shape the plan.

The AI clause and the spring 2027 meeting

The statement's AI content runs to two sentences: 'Recognising the speed of development in this domain, we will expand the Trinity House Agreement's Cyber Lighthouse Project to incorporate Artificial Intelligence,' and 'Through collaboration on a small number of shared military use cases, we will deepen bilateral cooperation in capability development, experimentation and adoption.' Writing in the Frankfurter Allgemeine Zeitung before the talks, Streeting said that 'through joint testing, development and ultimately the introduction of AI in our armed forces we will deepen our cooperation and keep pace with those who seek to harm us.'

According to Euronews, government and industry representatives from both countries are due to meet in spring 2027, and no specific AI systems, programmes or budgets have yet been announced. The statement also directs officials 'to maintain this momentum through 2027.' Since the agreement was signed in October 2024, German companies have committed £800 million (about €956 million) to the UK defence industry, including Helsing's Plymouth factory building AI-enabled underwater gliders.

Deep precision strike beyond 2,000 km, with uncrewed systems alongside

The centrepiece of the statement is a 'landmark project' to deliver Deep Precision Strike capabilities with ranges over 2,000 km within the decade; AI sits beside it as a new line. On land the two sides will 'explore cooperation on future capabilities and uncrewed systems,' and in the air the bilateral 'Flight Plan' includes 'future uncrewed and collaborative combat capabilities.' At sea, an Implementing Arrangement on Sting Ray torpedo procurement was signed the same day, and German P-8A aircraft flew from RAF Lossiemouth on exercises. Deeper space cooperation follows last month's leaders' agreement. The two countries co-chair the Ukraine Defence Contact Group and referred to the 'Coalition of the Willing' security guarantees.

Bilateral axes as the fast lane for AI adoption in Europe

Cyber Lighthouse was created under the 2024 agreement for information sharing and exercises; grafting AI onto it chooses a path of bilateral experimentation and adoption that does not wait for consensus in NATO or the EU. Limiting the scope to a 'small number' of use cases points to interoperable results in specific functions such as target recognition or logistics rather than a general AI strategy. Together with the UK–US defence AI and autonomy partnership of September, a layered set of UK-centred bilateral arrangements is forming the front line of military AI adoption in Europe.
