Germany and Britain agree to widen their Trinity House pact's Cyber Lighthouse Project to cover artificial intelligence

2 November 2026

Germany's Defence Minister Boris Pistorius and Britain's Defence Secretary Wes Streeting issued a joint statement after the second Defence Ministerial Council held under the Trinity House Agreement.
That agreement is the bilateral defence pact the two countries signed in October 2024, and the statement says it has since been reinforced by the Kensington Treaty.
They committed to expand the Cyber Lighthouse Project, which runs under that agreement, so that it takes in artificial intelligence as well.
They will begin with a handful of military tasks that both armed forces share, trying the technology out on those first before taking it further.
They also reviewed their joint Deep Precision Strike project, a long-range weapon of over 2,000 km range that is to be delivered within this decade.
On the same day the two National Armaments Directors signed an Implementing Arrangement on cooperation in Sting Ray procurement.
The statement records that German Navy P-8A Poseidon aircraft flew from Britain for the first time on an episodic basis, with support from RAF Lossiemouth.
It also notes that Germany and Britain together co-chair the Ukraine Defence Contact Group, that both belong to the Coalition of the Willing, and that the ministers want the work carried on through 2027.
