#S1 HMS Kelvin - UK Done

Hms stuart is v&w class leader also, of the flotillas, we've not a K. So for a completionist this is potentially desirable.
.

Legion is a bit of funny one. So the standardised L class is fair call.

You made a point about ships not being at the prescribed battle. I would point out they are examples of classes that were.
Under that criteria for secection you've got a v&w (hmas vampire noted) or a d class which hmcs ottawa represents

I would say to change this to an unrepresented early war DD class...

I also 100% agree we need to get a Black Swan into the game...

Hms barfleur is in one of the team decks and theres no K flotilla yet done

The J,K,and N classes are usually shown together since there's not really much difference between them. We already have a Javelin to represent them.

I would go with a non AA variant L or the Admiralty V & W instead personally.

It's a pity there isn't really anything else to go for from this battle in terms of alternate DDs. The other classes involved we pretty much already have from what I can see, although I'm not sure if I'm seeing the full lists of all the DDs from the various forces involved or not. One of the fleets on wiki just says 9 destroyers without naming them. The fact that seemingly only one K class was involved is surprising in itself but Kelvin is middle of the road in terms of Ks, some better choices, some worse. I actually think the starter has a couple of slots too many for each side in hindsight, which is forcing choices from this battle. A couple less would have freed up space for more flexibility. As it is this is more livable than the Peary option would be.

If nothing is to change regarding the starter criteria at this point I'd suggest

HMS Kelvin Remaining
HMS Peary Swapped for HMS Hyacinth
HMS Berwick Remaining
HMS Manchester Swapped for HMS Southampton

This would give two improved units(historically & game) over originally suggested, plus all the units still took part in the battle.

A compromise and a green light to move on and develop said units.

Thinking about other units with carrier orientated SA's, if the carrier is kept back, generally any offensive abilities are not used much. I would say decide if it's going to be mainly a defensive carrier escort unit (as in this battle) and if so, maybe swap raider out. It is an option to have abilities for both surface attack & defense but in my experience, because it involves carriers, it's stretching trying to do both. Unless obviously your a carrier charger!
