Defence: Continuous At-sea Deterrence

Lord Lancaster of Kimbolton Excerpts

Wednesday 23rd June 2021 Lords Chamber

[Baroness Goldie (Con)]

It is not a new royal yacht; it is a new national flagship. I think that is a very good thing, if I must make my opinion clear. The noble Baroness is correct that the MoD will be responsible for the initial cost of taking the flagship through the procurement process, but the source of government funding for the rest of the project is still to be determined. To the cynics I would say: this ship will have an important national security and foreign policy function. It is not a warship, and its primary role will be to promote trade and protect the nation’s economic security.

[Lord Lancaster of Kimbolton (Con)]

My Lords, if our nuclear deterrent is to be credible, it must also be viable. My noble friend mentioned two aspects of that viability—the continuous at-sea deterrent and having a suitable number of warheads—but is not a third aspect that we must not hand the advantage to our adversaries by being overly prescriptive about the circumstances in which we would use that nuclear deterrent?

[Baroness Goldie (Con)]

As my noble friend is aware, the UK has neither a first-use nor a no-first-use policy, and to avoid simplifying the calculations of our potential adversaries, we will remain deliberately ambiguous about when, how and at what scale we will contemplate use of our nuclear weapons.
