The United Kingdom and Germany have agreed to jointly test, develop, and deploy artificial intelligence in their armed forces. The plan builds on a 2024 defence pact and will expand the existing Cyber Lighthouse cybersecurity project to cover AI.
Why it matters
The plan is intended to deepen defence cooperation between the two countries and keep pace with those who seek to harm them. The International Committee of the Red Cross has warned that an arms race is already under way in military AI.
German companies have committed £800 million (about €956 million) to the UK defence industry since 2024, though no specific AI programme budgets have been announced. Details of how the joint testing and deployment will be funded and structured remain unresolved.
The players
Wes Streeting
Wes Streeting is a British Labour politician who serves as UK Health Secretary and announced the joint military AI plan in an interview with the FAZ newspaper.
Boris Pistorius
Boris Pistorius is a German Social Democratic politician who serves as Germany's Defence Minister and held talks with Streeting in Berlin.
Helsing
Helsing is a Munich-based defence technology company that builds AI-powered systems and opened a factory in Plymouth in 2025.
International Committee of the Red Cross
The International Committee of the Red Cross is a Geneva-based humanitarian organisation that promotes international humanitarian law, including rules governing armed conflict.
The details
Under the plan, the two countries will expand Cyber Lighthouse, an existing joint UK-German cybersecurity project, to cover AI in their armed forces. Munich-based Helsing, which opened a factory in Plymouth in 2025, builds AI-powered underwater gliders designed to track hostile submarines.

2025: Helsing opened its Plymouth AI glider factory.

Spring 2027: Government and industry representatives from both countries are due to meet to work out how the plan will be carried out.
Big Picture
The joint AI plan extends the 2024 UK-Germany defence pact into military artificial intelligence, following the bilateral framework that the two countries established that year. It places the two governments among the early national actors formalising AI cooperation within their armed forces, a field the Red Cross has already flagged as an emerging arms race.
For most readers, the plan has no direct near-term effect, since no specific systems, programmes, or budgets have been announced. Its practical impact will depend on how the spring 2027 meetings translate the agreement into defence procurement and deployment decisions.
The takeaway
Military AI is moving from research into formal bilateral agreements between allied governments. Readers following the topic should watch the spring 2027 implementation talks for the first concrete programme details.
What happens next
Government and industry representatives from both countries are due to meet in spring 2027 to work out how the plan will be carried out.
