This is an important issue—I would not suggest otherwise—but it is also a situation where we constantly factor into any decision-making what will be the likely transition period and requirements to maintain operational effectiveness, to ensure that there is no hiatus, gap or lacuna. The evidence suggests that that is effectively achieved. But it is worth pointing out to the noble Baroness, who raises an important point, that we were clear in the Command Paper refresh that, in procurement, we also look at exportability. There is proven success in that already, in relation to Type 26 and Type 31 frigates.
