When the chips are down (which is when things really count), I'm not sure any peer or near-peer enemy would regard the threat of an OPV greater than that of a carrier with a tailored air group.
You'd like to think that wouldn't you, but I wonder what a "...tailored air group..." will look like for our carriers. If we rely on our own (UK) assets, then maybe half a dozen F35s and a mix of helicopters covering ASW, AEW etc.
We've bought a pair of awfully large boats, but are not investing in much to go on them.
