AI sonar effectiveness

zed055 · 07-27-11, 09:53 AM

I have a question regarding the detection capabilities of AI-controlled units:

If, while in shallow water (under 150ft), the player sub is resting on the bottom, does this reduce the chance of detection for the surface units? My understanding of active sonar is that, if a target is resting on the bottom in moderate clutter, active sonar effectiveness is significantly decreased. Is this true and, if so, is this modelled into the program?

Currently running stock 1.4 without mods. Only been using the program for a few weeks, and I'd like to get a handle on the vanilla game before I start changing stuff.

Thanks!

Not in the game and unable to mod such. In fact, sitting on the bottom will eventually cause damage, it's like running into land.

While I haven't performed extensive testing in-game, I bottomed the Tambor-class USS Gar (SS-206) repeatedly attemping to evade a subchaser off Osaka (insert operative at Osaka mission). No damage resulted - which makes sense, since bottoming a submarine frequently happened during operations during WWII (http://goo.gl/aSrNX) in shallow waters. A modern SS(N) can't do it for various reasons, but the old boats could.

If you drift onto the bottom you wont take any damage. By drifting i mean lowering your depth, without forward propulsion. All stop, zero speed, dive planes set to go deeper then the bottom really is.

But no.. bottoming the boat will NOT help you. The only time laying doggo on the bottom is helpful, is if your about to enter a shallow water area, and your just waiting for night time to do it.

Duci explained better, if I sit at the bottom actually touching land so that it rubs, even at 0, given enough time you can get minor damage, but never more than a few percent, you drag bottom with any speed damage will increase.

Some use a minor glitch, if you set 0 speed, planes to go deeper than the bottoms actual depth, you won't take any damage at all.

Still, you get no sonar effect hiding from sitting on the bottom in the game.

Course in a crash out of control dive due to damage, I would rather hit bottom than head for the deep.

It is my guess that active sonar will simply hit you and bounce back, regardless of you being in the bottom or not. Shouldn't make any difference towards detection.
