Now on stage at the Security and Defence Conference at Chatham House: Drones: The defence buzz word. Exploring how widespread drone use could signal the rise of autonomous armies and reshape armed forces training.

'Drone is a catch-all term now that can mean all things to all people. They can do almost all of the roles that we perhaps gave our assistance to, some better than others. I think it's therefore important that we understand which of those are applicable to us going forward. There is no doubt that these are as relevant to the land of maritime domain as they have been to the air’ - Air Marshal Greg Bagwell CB CBE, Distinguished Fellow, Military Sciences, Royal United Services Institute

Next up at the Security & Defence Conference: Defending the digital frontier, exploring why public/private collaboration is crucial and how adversaries are testing governments.

🗨️ ‘When we look at Ukraine, there are great examples of private tech companies doing really crucial work, showing how critical tech companies are to resilience. They are examples like Starlink, which haven't had the kind of regulations of being subject to personal whims, which shows how important it is to establish a process for these kinds of things.’ - Dr Nayana Prakash, Research Fellow, International Security Programme, Chatham House

Just wrapped at the Security and Defence Conference 'Show me the money: Defence banks and the future of public/private collaboration.' This session explored how rising defence spending is reshaping public/private partnerships and whether commitments can be delivered.

‘One of the benefits of any multilateral bank is that they have the ability to finance multi-year, so you can start to smooth out some of the lumpiness that occurs in pretty much every defence budget.’
- Rob Murray, CEO, Defence, Security and Resilience Bank

‘Deterrence rests on three main elements: cohesion, capability, and credibility. At the Munich Security Conference, we heard two complementary messages: the United States reaffirmed its commitment to the transatlantic bond, and the Europeans recognised the need to carry more of the conventional defence effort. This is not the transatlantic disagreement; it is the nature of evolution, of a mature and strong alliance.’

- Admiral Giuseppe Cavo Dragone, Chair, @NATO Military Committee

Day 1 of the Security & Defence Conference 2026 kicks off with NATO and the Future of European Defence, exploring 5% GDP defence spending across Europe.
