Visible underwater

Binary101 · 03-05-08, 04:18 AM

I dont have SH4, i like that the water is much more transprent, but i was just wondering i've seen some arial photographs of submarines at periscope depth and was wondering under what conditions are submarines visible underwater and at what depth will they not be visible, also were there any uboats sunk becuase they were spotted and tracked even underwater and can this be implemented into the game?

Ive recieved quite a number of complaints having modded the game to do just that. :rotfl:

It's a bit unrealistic to me. If you're in clear, shallow waters maybe. Then there's light reflection/refraction from altitude to consider. Also visiblity- fog, etc. I placed a contract out on Duci for that.

:rotfl: Just kidding!

It wasn't uncommon in the Mediterranean and I imagine water conditions in the shallow South China Sea were similar. Gonna have to train my flak gunners to fight in scuba gear.

You should be safe in the deeper blue ocean tho.

The open Pacific Ocean waters are remarkable clear. You can easily see objects several tens of feet below the surface on a sunny day, so I have no trouble imagining that a conning tower sitting a few feet below the surface would be clearly visible from above (remember periscope depth on the guage is keel depth).

And, while I cannot find it right now, one of the US Navy web pages has pics of a Los Angeles class boat at periscope depth taken from a supply helicopter coming to rendevous with them - you can clearly see the whole boat in detail below the surface (the pic was obviously taken on a nice clear sunny day, during some NATO exercise if I remember it correctly).

Yes, but that's just a selective case. What about in bad weather conditions and night? Unless the pilots got night vision goggles it's next to impossible unless the plane is flown a few feet and 4 mph from the surface, directly above the sub.
