The Evarts and Somers Classes aren´t using either their hydrophone or their ASDIC.
You could reproduce this by going into the editor, placing the ship and a submerged sub a few hundred meters in front of it.
You could go ahead flank without being noticed. After I went to the surface to be spotted and submerged when they fired on me the ship is dropping DCs on the exakt position and in very shallow depth where I submerged and is still not using hydrophone or ASDIC.
I tested this in every year of the war with only WAC 5.0 and the Patch to 5.2 activated...

And the Fletcher class is converted to the DCRack_SH4, but has the node positioning from the DCRack which leads to wrong positioning...
