I think the Auditor General's report points to awareness gaps, and we've talked about air, sea, subsurface just now and land. It's all of these things coming together that actually get you to all-domain awareness, and that is where the armed forces is looking to go in terms of the investments and upgrades it intends to make. A big part of the story is NORAD modernization, which we've already spoken about, but subsurface is a key one going forward, absolutely.
