Help needed! Sonar spotting ships when surfaced!

[AS]

Hi all, maybe this has been discussed before, but I´ve got a problem: Since I installed patch 1.3 my sonar man reports contacts when I´m surfaced. On the other hand, my radar does NOT work in manual mode (although equipped), but occasionally (and as i think also randomly) spots contacts. I´m in the beginning of a new career, early war, GAR-class. Any comments? Thanks in advance. And yes, I had a clean install, no Mods whatsoever. Cheers, AS

Yes, after 1.3 the sonar detects ships while surfaced. Being it was possible under the best conditions and the sound gear is found under the chin of the boat, this was implemented in 1.3. I can say from first hand experience that the sonar will work while surfaced. Do I think it is too good at detecting? Yes! We do not have natural interference found in the real world. But, I can count the turns from the water taxi in the inner harbor of Baltimore on the sound gear on the USS Torsk. Bear in mind her engines are off and the water in the harbor is almost always very calm.

Thanks for your quick reply. Do you mean to say that US subs were able to use their sonar while surfaced? I didn´t know that. German U-Boats couldn´t, that´s for sure. Well, the Atlantic is much rougher than the Pacific... Cheers, AS

If you do not want to have that hability... just down the max sensor height under the sub draft, but be sure do not move it under the sub keel depth when at periscope depth or it will not works at peri depth.

You must to individualize wich sensor is it... then in example for a sub with draft 6 and peri depth 15 move max sensor height at -10.

Hrm I thought the passive sonar (directional) head was on top. The balls under the 'chin' were the active sonar.

@Steamwake,

These were for supersonic noises I believe. Under the best conditions they could be used and only with close proximity of the noise. If you read some of the accounts, the sub could be surfaced with slow turns on the engines for reduced interference and prop noises could be picked up. It is and was possible. But, with that said, the chin sonars are too good IMHO.

Subsonic maybe ? Thats kind advanced technology for the era.

Correct me if Im wrong but sonar working on the surface, well 'surfaced' with 1.3. Prior to that everyone was bemoaning the fact that the sonar cut off at periscope depth.

I personally think that not working or seriously degraded at pd is the way it should be. :hmm:

No doubt. It is just too good.
