so, this is a first: we took damage from a depth charge attack. almost all of the equipment in the control room was damaged as well as the forward compartments including the battery and the sonar/hydrophone.

every piece of equipment was repaired according to the systems screen however, the next interaction we had with enemy shipping, it was discovered that we could not longer detect shipping with our hydrophone. so, it seems, like the torpedo tubes, that there is a piece of equipment that is undocumented but still damagable, that can prevent the hydrophones from working.

i am going to save-exit-reload and see if that fixes it, just in case this is a SH4 "feature".

p.s. save-exit-reload did not re-enable the hydrophone, so it must be damaged beyond repair.
i looked at the S-42 upc and there is only two pieces of equipment: the listening gear set and the passive sound head (ball) and both have an entry in the system's equipment display.

question: where would one find the undocumented piece of hydrophone equipment that was damaged beyond repair but is not to be seen during play, if it is not in the UPC file?
