O.H.Perry is also specialized ASW platform with weak bow hull mounted sonar SQS-56. Main strenght for O.H.P is TACTAS. Other navies choose different way for ASW - active VDS and powerful bow sonar which requires large hull.
But those solutions means very effective working in active regime and moderate in passive. O.H.P is weak in active but very effective in passive regime.
Latest version of RA improve Udaloy ASW possibilities in passive - not active regime of working. Active parameters are sill the same as in RA 1.40.
(Bow MF active in RA 1.40 and RA 1.41: max speed 15 , Nrd - 12)

Afterall SQR-19 still have much longer anntena than combined VDS on Udaloy. That means Udaloy spectrum for frequencies should starts higher than 50 or even 100 Hz.
I know Naval Sim Engine isn't perfect and some parameters are difficult to simulate. But now Udaloy (from 80's) have best sensors for passive detection in all game.
SQR-19 was revolution in passive detection and even today it is very sensitive sensor.


I know that, last picture was mainly to compare versions of RA for most popular units - not for comparsion subs and ships

EDIT:
The Project 1155 dates to the 1970s when it was concluded that it was too costly to build large-displacement, multi-role combatants. The concept of a specialized surface ship was developed by Soviet designers. Two different types of warships were laid down which were designed by the Severnoye Design Bureau: Project 956 destroyer and Project 1155 large anti-submarine ship. The Udaloy class are generally considered the Soviet equivalent of the American Spruance-class destroyers. There are variations in SAM and air search radar among units of the class. Based on the Krivak class, the emphasis on anti-submarine warfare (ASW) left these ships with limited anti-surface and anti-air capabilities.

Never underestimate your opponent
