This optional test patch for TWoS v2.x.x will disable AI escorts ability
to detect surfaced targets with their hydrophone up until late 1942/early 1943 at which point most of in-game escorts will be equipped with on board radar anyway.
This addon should make early war night surface engagements somewhat easier and more realistic.
Enable it with your JSGME in bunker and continue campaign.
