They need to slow down to use their own ship sonars. If they are going full speed you have to rely on your helicopters to use dipping sonars on positions ahead around the group. Burke use bow sonars and passive towed array sonars but lately some ships have upgraded to using active towed sonars (VDS by European lingo) whereas all of 052D, newer half of 054A and all of 056A come standard with VDS along with obligatory hull and passive towed sonars.
Just because a ship must slow down to use its ASW sonars, having the ability to go fast ( 30 knots) is still a useful feature.

If the Type 052D - destroyer already has towed array sonar and variable depth sonar, then I see very little reason to give the Type 054B - frigate the ability to sustain 30 knots. It does not need to "run" with the carriers. The job of frigates, destroyers, and cruisers is to complement each other, not compete against each other.

I don't have access to that kind of data. I am basing this also on what I hear from shilao podcast. They have talked several times about inadequacy of 054a for carrier groups.
What is the shilao podcast? Does it have a more official name? I can't find it when searching "shilao" or "shilao PLA" on google podcasts.

The point is that a Frigate is supposed to be a low-cost complement to the Destroyers

I agree a Frigate should be cheaper than a Destroyer and likewise a Destroyer should be cheaper than a Cruiser.
Maybe a frigate can do ASW and convoy escort, a destroyer can do ASW for the CBG, and a cruiser can do AAW?

I know convoy defense has not gotten much attention since the end of WW2. But in a WW3 scenario it's definitely coming back.
