Paul:
There was a more recent article, like a month ago, stating that 2 more Aegis ships were deploying with Standard-3's. We have probably 2-3 times the number of seaborne ABM's than this article states, since the number of platforms went from 1 to 4 very recently.
Actually this article is from today. I suspect you're right that the opinion howver may be slightly dated in info, but not by much. It's got the general limitations pegged. As for 2-3 tiumes the number of SM-3s, that may be possible. But it remains a glaring fact that this is just grossly inadequate. We have 80 or so Aegis cruisers. And only just now three that can engage ballistic missiles?
