I know you didn't say that. I never said you did say that it didn't (
).
Anyway, we're still comparing apples to oranges here. The Perry is a frigate. The Udaloy is a destroyer. I hope it's more survivable, but even if it is, it does not in any way mean that the Perry's defenses are inadequate. What I'm getting across is that the Perry, with it's seemingly lacking armament, can still hold it's own against large threats such as missile-armed destroyers.
And with the whole "10 missiles" thing, again, unless they are advanced, sea-skimming supersonic ASMs (like the -27s), the Perry will still be able to defend itself. Chaff will lure some away, the SM-2s will pick off most at long range, letting the CIWS mop up the rest that get through.
One more thing. The whole "20 mile limit" on the helos only applies when they stop. When they move, they do so at greater altitude, thus extending the range at which you can use them. Besides, a sub at greater than 20 miles isn't much of a threat to you, and you aren't much of a threat to it, helo or no helo. Get in there and do your job, you're an ASW boat after all!
