Yep that youtube chap I linked above it's his thing. Here:

If you do as I said and play UK or US then you really need to do the following and you won't got too far wrong:
Carriers and the bulk of the close air defence eg for the US Aegis capable cruisers at the centre - then run some anti-air and anti-sub ships as pickets at say 2 and 4 o'clock presuming you are moving from W to E (I run with them about 20-30km ahead), with a picket behind (20km) - all the way infront (100km+) I use an attack sub. All sensors need to be passive until you are actively prosecuting a target. You should scout with your air for the US Hawkeye. An enemy on approaching your group should only really see the airborne early warning places up - they are the eyes for everything above the waves, when you pick up something below the waves you can prosecute it with helicopters etc. You need to keep up a fighter patrol over the centre and ahead and another group on ready 5 to again prosecute new contacts that way you can attack any inbounds with quickly.
Play it like poker don't reveal your hand too soon (ie makeup and location) and most of the relies on not making your sensors active - naturally if you think an attack sub is 10km away and running your way ping the water with every sonar you have!
If you were attacking such a group then you have to attack radially eg I would split my planes to attack from N, S, E, W so all the missiles arrive the same time to overwhelm the Aegis systems. If you can get an attack sub in then it may be better in such a case to remove the pickets and the Aegis cruisers than going for the carrier straight off.
