It give me great pleasure to agree with the noble Lord—it is refreshing and, I hope, a recurring experience. The noble Lord makes a very good point. As he is aware, we currently have Vanguard that will translate into Dreadnought in due course. On the Astute class, the final two submarines are still being built: boat six, “Agamemnon”, and boat seven, “Agincourt”. They will make an important contribution, but as we move on to the Astute class, the noble Lord is correct. We are aware of diverging maritime challenges, not least in the high north and the Arctic. The MoD is cognisant of that. I referred to the fact that we have published our Arctic strategy to his colleague, the noble Lord, Lord Robertson of Port Ellen, on Friday.
