Torpedo Depth in Relation to Draft

Osmium Steele · 04-20-11, 09:35 AM

For magnetics, I set the depth at 1m below the target's draft.

For impacts, I usually set depth at 1/2 the target's draft.

If the running depth is too deep, high sea states can cause the fish to miss under the hull.

I'm not sure how closely it is modelled in SHIII, but historically, high sea states could wreak havoc on torpedos set too deep or shallow.

Iirc, someone here once had a fish leap out of a wave and hit the target's superstructure.

Now THAT's something to get a screen capture of!!

Too shallow and they could broach, or break the surface, and go crazy.

Too deep and they would simply miss.

I was in some shallow water not long ago and had an eel hit the hull and fall away as a dud; but then detonated when it hit the sea floor (5-10m below.

Shooting too shallow at an enemy sub may cause the torpedo to go OVER your target in heavy seas. That's quite frustrating...

Impact setting...3/5 metres depending on how deep the draught is.

If the sea is smooth then setting my torpedoes for around 1m under keel depth is usually okay. If it's heavy seas then I usually stick to contacts, unless my firing angle is too great when I will use magnetics but will set them 1m lower again as I have had a lot of torpedoes bounce off the underside of the ship in heavy seas.
I get the impression that a magnetic hit causes more damage than a contact one, but the longer distance you shoot it over, increases the chance of it prematuring. I once fired four magnetics at a Revenge battleship in heavy seas at long range, three of them prematured and the fourth ran under her without exploding!

I fired four at a large merchant once in heavy seas...

two detonated prematurely, once passed under without detonating and the last one hit the hull without going off! That SUCKED!!!
