Destroyers.  If I could command my own destroyer - USN Fletcher class or RN Battle classe - that would be good.  I think we already have the Fletcher in the CV groups don't we?  Put in a bridge, a wheel, let me set the speed, course, let a friend join in the gun batteries or let me command them all at once, just like a bomber.  And Torpedoes.  They should have the torpedo option.  Maybe even sea mines.  Mines would be good too.
It would also be cool that if a destoyer was hit, she would start to sink and burn - listing to either port or bow/stern depending on where the damage was rather than just going 'poof' and then it appears as vertical rock.
I'd even pay perkies to command a destroyer.
