Surface hydrophone fix?

IonicRipper · 01-07-12, 12:46 PM

Is there a small mod/fix to stop the hydrophones from operating on the surface?
I know there is one for SH5 but i dont remember ever seeing one for SH4...

US Subs had their hydrophones, the round ones, mounted below the waterline so that when surfaced, they would still work. The JT listening gear available later in the war, mounted one on the port quarter foredeck, but they still had the older gear as a backup, and when in the middle of action, the secondary unit seved to keep the skipper informed of what was going on around them so that a DD couldn't as easily sneak up on them.

Huh... I was sure those were just cause i had a male sub...

But seriously i was convinced they were the sonar equipment, had no idea fleet boats had 2 hydrophones

The S-boat does not have the submerged hydrophones while the fleet boats do, so, if your in a Sugar Boat and spot a warship at random with no Hydrophone contact don't be alarmed.

On the other hand, reading the articles I found this:

Quote:

As soon as your submarine surfaces, secure the JP gear,
1. Turn the power switch off.
2.Train the hydrophone to 090 degrees if it is installed on the port side, or to 270 degrees if it is on the starboard side. 3. Hang up the headphones carefully. They are a special kind that cannot be replaced while you are on patrol. Other headphones do not work as well on JP gear.

-page 26

This indicates that the hydrophones were switched off while surfaced, making it hard to pick up contacts.
