That's a fair point Erik. Sea Cat is intended to replace the 40mm Bofors, in its earlier MRS-3 guided form its no anti-missile missile. It does well at close-in AA work but its subsonic. Orange Nell is not an area-defence weapon, that role is for Sea Slug, Orange Nell is designed as an anti-missile system. In effect the Type 80 is a goalie. Now I could have made her a double-ender and put a second Nell aft instead of the flightdeck but that would have meant losing the Wasp and possibly Limbo. I wanted the Type 80 to have an ASW escort role too, she meant to be a Type 12 with the 4.5in replaced by a missile system as the Admiralty intended doing. She is a goalie protecting the carrier with the County or Admiral (both of which also have Nell) further out for area defence. I figure the vertical 40-round magazine would be pretty bulky and would require a lot of internal space.
And because Sea Cat is light it makes sense to fit it to make a double-ender ship without the loss of capablity and gorwth in hull size and weight two Nells would require. Like everything, you have to compromise somewhere.

I am considering the torpedo tubes; should we go for an exchange at some time to Bidder or Fancy? if the former I'd need to factor in sonar so together we have asw self defence; otherwise we have escorts to provide asw. And Fancy offers anti-ship capability.
