Once you equip with a Wildcat you have included most of the offensive capability of a frigate it makes sense to include modular options for 1/3-1/2 to be equiped to deal with a sea skimmer fired from the shore, or help out with ASW in a major Falklands type operation.We're not configuring half the RN to do small stuff, we're taking the existing class of MCM vessels (something like 12 in all) and also the River class OPV's plus a pile of other vessels and replacing them with a single, larger, more flexible hull that can do MCM if needed, easily handle extended patrols, sea control duties, and can easily overwhelm any number of blokes with RPG's as needed. They could also take on a large chunk of say, the Iranian Navy and come out on top as they're largely using small boghammers etc - 40 knots won't outrun a burst of 76mm or a Wildcat firing Sea Skua or the latest beam rider from Thales.
What we're not doing is the thing 1805 is always protesting the RN does and gold plating it by fitting it with kit which it won't need for the role and which will compete with resources for the Type 26. By not fitting with or for roles it's not designed to handle we can buy more of them and have a reasonable chance of rounding out an otherwise depleted fleet.
If you start specifying FLAADS/Artisan plus other "GP" fit items, the cost goes up and you're basically going to lose type 26's to this cost spiral.
Nothing wrong with working in space for RAM (twenty tons of topweight and needing little support other than a basic search radar) and by all means leave some hard points and power worked in for Exocet if it can be done easily but let's not make this thing £200m or more by tacking on extra kit.

There would be no point in SSM, but a fit of say 16 CAMM or alternatively RAM. T26 numbers will be low why not anticipate and focus on a fewer highend ships and have the option to back up with 8-10 TAS. the advantage of a modular approach would be near 100% availablity you to available active ships.
even if the ships fully fitted did cost £200m it would only be a c£100 marginal increase for as you would be spending the £100m for the C3 roles anyway. I am assuming patrol and survey work can be dropped in a major crisis. So if 8 ships fully fitted a cost of say £800m worth the sacrifice of a couple of T26. Its the 80/20 rule, these ships would give you in a single role 80% of capability for 20-25% of the cost.
