I will play this one later and see what I can find but from memory having played the Perry substantially id advise trying the following:
1: Run broadside to the threat this will enable the SM2 to engage but also the CIWS also gives you chaff and flare, and maintains you weapons arcs
2: Make sure your CIWS is on to automatic mode not fully as you dont want to take down your own missiles
3: You need both air and surface search radars on otherwise the SM2 just goes anywhere
4: at this moment in time you should stay in the weapons control system
5: Judicious use of clicking the SM2 reload until it flashes its loading
6: for every time you reload unassign and re assign the contact using the buttons
7: fire 1 for 1 and start with the closest missile to you then take the platform firing
8: weapons quick launch will help but if your playing without it the SM2 can take around 30 seconds to load each missile
Unfortunately if your playing stock 1.04 the chaff and flare feature don't give you anything, neither does running at flank speed and turning (your basically destroying your weapons arcs)
The last time I played 1.04 and the Perry would have been around 2010 I currently use the RA mod
This guide may assist you as well it was Written by Oneshot I uploaded it some time ago its dated now for anything past 1.04

ASW operations in the Perry
I stress this point have the nixie streamed !
Speed is not an advantage in this theatre, in fact going above 5 knots and your basically giving them yourself on a plate, you need both helos in the air during ASW operations.
Depending on the area will depend on the patter you use I tend to split my helos one working in front one behind in open water, and if in confined waters I use them both ahead and working from the furthest point towards each other to form a barrier.
I use a datum prosecution pattern in open water this happens up to 10nm from the ship on the fist drop imagine a circle 10nm in diameter and at the 12 3 6 and 9 positions i place vlad type buoys (passive) and in the center dicass (active buoys) no buoy should be more than 5nm from the center (you can measure using the alt enter and then push enter to mark the nav map.
I will lay several of these patterns spread apart behind and in front of the ship and if needed to each side while maintaining 4/5 knots, do not stray into your own sensor field is completely screws up the sensors and gives the opposition advantage.
in Barrier formation each buoy is like a string 5nm apart and a vlad then dicass vlad dicass pattern, alternatively you can stagger the line so its off set to cover a bigger barrier area.
Tomorrow I will get something going and post some screen shots so you can follow but note I will be using RA mod, the tactics are the same just a different platform most likely. (I mainly only use the Udaloy now)
