How many VLS Ticonderoga class cruiser needed to defend pearl harbor from japan air strike back in WW2?

Question

Assume we could send modern and well equiped VLS Ticonderoga class cruisers back in time to pearl harbor 1941. How many ship we should send back to defend pearl harbor from japan air strike? Is one ship enough?

I asked this question to explore how much technology can influence end result in a battlefield

Answer 1

what a moron. go suck your moms t*t you noob.a

Answer 2

Well, based on the sophistication, and firepower of such a vessel...

And assuming they had enough ammunition to shoot down some 600 Japanese planes...

Probably only 1.  All they would have to do would be intercept the Japanese Carrier Task Force... a few hundred miles outside of Pearl, and blow them out of the water.  

Alternatively, if they could be sent back to arrive a mere 3 hours before the attack, they could warn the US Pearl forces, and Pearl could have defended itself.

Alternatively, If they were sent back a mere 14 days earlier, then Pear could have sent Enterprise, Yorktown, and Hornet out with the VLS.  The VLS's radar would "see" the j*p fleet, and the Big E's planes would do what they did at Midway.  (Though instead of "Remember the Arizona!", you might have "Remember the Enterprise!", as your battle cry. This would of course change the history of Star Trek.  Maybe not a good thing???)

Now, if you can only send them back a few minutes before the infamous attack, it depends:

How much protection do you want to give?

If you want to totally defeat the Japanese, send 3 of them.  Equally spaced out along the Japanese incoming line of attack... then none of their planes could get through.

BUT:  If you only want to change history a little bit, send 1 ship....  

If you save only 1 ship:  The Arizona, then probably the US does not enter the war, and the Axis wins.  

Hummmm.....  Maybe not good.

OK.

So we lose the Arizona, and you save some of the other ships. (I don't like that scenario, being an ex-Arizonan, but...)

Of course, if you can send back 6 of them, along with "indefinite" supplies, and they can stay for the whole term of the war, then the USA might be able to conquer the world....

So how much history do you want to change?  That is the question!
