Hydrophone

Hi guys,i am picking up contacts when the boat is surfaced.Did fleetboats have this ability or is it just how it works in SH4?I don't know much about these submarine types so would be grateful if the experts here could let me know if this is realistic.

thanks and good hunting

Yes and no. There are three hydrophone sensors on the boat. On deck and rotating in your sight is the audible range sonar head. Of course, being on deck, it's not wet when you're on the surface and so doesn't function.

However, under the keel at the aft end of the forward torpedo room are the two supersonic sonar heads. They work at ranges outside the frequency the human ear can hear and are very useful, even on the surface.

The sonar operator's manual made it clear that these continued to operate on the surface and directed the sonar operator to continue monitoring the supersonic sonar while on the surface unless ordered by the Captain to stand down. This indicates that they expected to develop contacts from sonar while on the surface.

Thanks for the answer RR.Been playing modded version of SH3 where the boat had to be submerged to use hydrophone.It's gonna take time to break the habit lol.

cheers and good hunting

Yup, the American boats were different with those chin mounted sonar heads under the hull. They could be retracted so they weren't damaged in case of contact with the shell of a very tough planet.

Is it just me, or has anyone else noticed that with RSRD installed (over stock game for me) that you don't get sound contacts when surfaced? You only get them after diving.
