In other words, I can read and go with the facts and you cannot. Feel

I don't have an "argument", you stupid git. I'm just correcting his
facts.

And the weight of both of them changes as they burn fuel. So what?

:SM-3 is a derivative of SM-2 ER Block IV. For the purposes of this argument

:

Do you know for a fact that a VLS cell that will handle SM-3
(essentially a 4 stage missile of much greater weight and height) will
handle an SM-2ER? I don't.

Do you know for a fact that SM-3 with a LEAP warhead even *has* a
secondary anti-ship mode? I don't. Again, the guidance is *VERY*
different.

Look up the guidance for SM-2, you stupid clod.

It certainly makes you easier to shoot down. It also screws up
guidance for this particular missile.

Fine, don't run them. You've just shown you're merely a loudmouth
