We certainly should develop one, and we are developing one. My noble friend is right to highlight that. We are undertaking a number of actions including surveillance aircraft from Lossiemouth, the ship “Proteus” looking at how it protects underwater assets, and the Royal Navy ship “Stirling Castle” looking at how it might operate drones from its deck to secure underwater pipelines, data cables and so on. We are doing a lot, but my noble friend is right to point out the importance of this.
