Hello again!
Thanks everyone. Pennant numbers edited, the new ones were (according to Navypedia, which seems to work again) never assigned to any capital ship, cruiser or aircraft carrier.
@Hood: Thank you for checking. I figured the 982 would function as a target indicator for the Sea Slugs, with the 992 forward indicating the targets for the 76mm and the Seacats and the 984 working as the main air search set. I was surprised how long the WW2-era 277/278 antennae remained in service (the 1960s Counties still had them), so the Admirals retained them too throughout the 60s. The 974/978 forward would be the navigation radar. That's what I thought anyway; I might be totally wrong, though
Greetings
