rather be on a Battleship when taking a torpedo hit or on a Destroyer
As I tried to point out above, comparing a battleship to a destroyer is not a fair comparison. Compare it to a carrier, and yes, I'd rather be on the carrier.
4 Battleships for 1.7 Billion or 4 Destroyers for 3.6 Billion. Which has greater offensive capability?
Against what kind of target?
Aircraft? The destroyer
Submarines? The destroyer
Surface ships that fire missiles at you from beyond gun range? The destroyer
Targets further inland than gun range? The destroyer
Which A: Carrier or B: Battleship can deliever more ordinance
Again, choose your target. Against Kabul? The carrier can deliver infinately more ordnance, since the BB can get exactly 0 weapons there (well, the BB refits have a few tomahawk launchers, bet IIRC, all those missiles have been retired, so still 0)
Against Baghdad? Same thing - the BB can't even touch the target.
I know we lost a lot of CARRIER based planes in vietnam
Surely you realize that was because of the asinine political restrictions on the air war, not due to any defect of desine or usage.
Carriers are great for what they do but they are not designed for Marine Landings
Quite a good point, but irrelevant. US policy is to not to do 'opposed marine landings' again.
I read that they even made Nuclear shells for the Iowas back in the 50's
True, but they never left mainland USA. Their usage was....questionable. The BB just couldn't fire far enough to be outside of fallout range. It was kind of a 'fire a broadside, and leave the area REAL FAST'.
Our carriers regularly deployed with nukes up until fairly recently - and still, as aircraft hardpoints are essentially the same throughout the US military, any carrier can be outfitted to be nuclear capable during any UNREP. It goes without saying a carrier could puke that nuke down WELL outside of any potential danger range to the CVBG.
