Go quiet.. lay down..

Is it more difficult to detect a sub that resting on the bottom? To me it seems like it, because when i dive in shallow waters i do this some times to avoid getting detected, i think its more difficult in distance.

Did anyone of you tried this and whats your experience?

You would think that would be the case due to the sea floor being noisy. you would think it would also reflect the sounds of the destroyers and make it harder for them to here you as well. As far as active sonor I guess they are aiming at anything higher then the sea floor. the top of the boat is 40 feet above the sea floor. Besides they will just debth charge your last known location. If your close to that your in for a hell of a ride. Your best bet is to creep out of there slowly. Once you get some distance Secure from silent running and run at a higer speed till you clear them. I would also immagine that DC's going off would help mask your sounds as well. I always keep moving as much as I can. Change heading often and keep them behind you.

Its actually easy to ping out a long tin can setting on a bed of sand and rock.

It's not a tactic that I'd recommend (and it was not submarine doctrine that I've ever read about). I have used this in game in a couple desperate situations though and have had it work once. The subchasers that were after me went all-stop and lay to listening. After 30 minutes of waiting for them to do something (they didn't--remained silent) I came up 10 feet and snuck out. I considered myself Very Lucky!

See that flapper A is closed, Gate Valve C in discharge pipe is Open, Valve D in water supply line is Open. Open Valve E to admit nessecary water. Close Valves D and E. After using pull Lever A, Release lever A. Open Valve C in air supply line. Rock Air Valve Lever F outboard to charge measuring tank to ten pounds above sea pressure. Open Valve B and rock air valve lever inboard to blow overboard. Close Valves B, C and G.

That's insane! I'm just gonna hold it til we get back to port.:eek:

I've had mixed success with this. Sometimes I get away with it ... other times I don't.

Agree. Grounding not a sure-fire tactic. My opinion it's always best to keep moving when the enemy already knows where to look and listen. Better for them to drop DCs where you were rather than sit there and wait for a lucky bracket effect.

Once the DD's Know you are in the area its not a good tactic. However sitting still on the bottom before they are alerted by an attack/presence, their chance of "knowing" a US Sub Lying in wait is there should be slim to nill. WWII sonar of any nation or type wasnt that good.

That's not what the captain of S-38 said. He grounded four times while under attack, and evert time the Japanese sonar lost him. There was the added benefit that the sand absorbs the shock of the blasts, or at least deflects it.

If the water was shallow enough, grounding was considered an excellent tactic. Unfortunately it makes no difference in the game whatsoever; or so I'm told.

Nice article!!!

I'm not sure about grounding not working in SH4. The only times I've tried it is because I couldn't lose the escorts that were after me. And it has worked twice (once was just last night). But!!!!!!! It really sucks when it doesn't work :nope:!

"... If the water was shallow enough, grounding was considered an excellent tactic..."

As far as the GAME (as opposed to a particular historical reference) grounding is not a sure tatic (depending on circumstances) and is not likely to work in shallow water. If you can go deep enough, works sometimes and sometimes not depending on the skill of the enemy at the time.

With all the above said, what is the purpose of the discussion? What works in the game? Or, what you think AUGHT to work in the game?

In the real world, you cannot always count on sand under you and going to ground on a pile of rocks or a reef does not sound like something any real world commander would do as a matter of 1st choice.

-PV- My first thought was, what work in the game.

And if it helps grounding in farly shallow waters, does my chance of detection go up or down if i travel just a few feet off the bottom, like real close.

Grounding in AOD worked great...except for the part where you got stuck in the mud. In SH3 it didn't work at all, as I recall. I'm sorry I misspoke; I haven't been able to experience SH4, so I don't know.

As far as real life working or not, I was only responding to SteamWake's comment on how easy it would be to find the sub.

Also as far as real life goes, I suspect that it's in a similar category to P-47 pilots talking about escaping German fighters by outdiving them: the ones it worked for talk about how great it was; the ones it didn't work for aren't around to talk about it at all.

I think it depend on the surface on the bottom, mud and sand i guess absorbe the ping waves, so the sub can be spotted more easily than a sea bed og rock and more solid materials....
