Default Torpedo Bug

i dont really care if this has been posted before and im not going to read through dozens of posts to find it so,

i think i have a major bug with the torpedo running depth. i play with 100% realism with no external view and every time i get the perfect solution, my torps always miss. I became curious on how i always missed and decided to go on a patrol with the external view on to see how i was missing consistantly. When i came across a lone merchant, i calculated the range, AOB, and speed using the length/time * 2 equation. I shot 3 torpedoes at him at the default running depth of 6 feet and guess what...they ran much deeper and went right under the little bastard.

i just wanted to know if this is a known bug and if it will be addressed in the 1.3 patch.

again, i didnt want to look through alot of posts to find something like this, so please no one flip out on me.

If you're playing a career that's before '43 you'll find your fish do that, Mk 14 Torpedoes in real life tended to run deeper than they were set for, so it's not a bug, it's a feature. Adjust them accordingly.

They on average ran 11 feet deep. In RL they calibrated the depth based on a dummy warhead that weighed less than the real one. When they added live warheads, the heavier torps ran deep.

I have pretty much given up (for the time being) on using under the keel shots due to the problem stated above. Can anyone tell us if the depth discrepecency is consistant, and if so, how many feet shoud we compensate for? i.e, if I wish to set 20' under the keel, what setting should I use, or how many feet should I subtract? This is using imperial measurments.

What Ive been doing for under the keel shot is to look up the keel depth and set the TDC to that depth and not under. So if the rec. manual says keel depth of 11.8 feet I set the TDC to around 11.8 feet, not 12.8 knowing the torps tend to run a bit deeper than what the TDC is set for.

I have 'fair' success with this but actually rarely use beneath the keel shots. Espically with tankers. With tankers the shallower the better seems to be the case.

I was shooting using the hardcore torpedo mod near the edge of arming range including the closing range, and when the stopwatch gets near projected impact, THUNK. "Torpedo is a dud, sir."

Doh!

Was cool I heard it.

Default Torpedo Depth

Well I was PI($ED last night by this "bug" (??). No tasking orders, full loadout... lets go hunting, so I made my way to Japan (time to show them what Pearl felt like) and made my way up into the bay w/ Tokyo and the other cities. Found several capitol destroyers moured in the bay. Lit one up (have to check the classes when I got home) but I know it was a 33k ton'er. 3 fish from the stern tubes made quick work of her at 1000yrds, and the secondaries were awesome. Moved up a little ways and found 2 more, one almost same size, another around 25k tons. With the patrol craft fumbling around trying to figure out WTF just happened, i closed on these 2 to 1000yrds and let 3 at the big destroyer and 3 at the smaller one. The large destroyer blew like a can of gasoline and was on the floor in 60 seconds after I set off one of her powder mag's.

Okay... so the second.. HMPH, destroyer, I watched (ext. view) all THREE of my fish run quietly below her keel. Problem was, I had set all the fish as shallow as possible. This has been a recuring problem with both merch's and smaller naval ships. I'm emptying my tubes at these boats and nothing. Just to be ABSOLUTELY sure, I fired off my last stern tube at the small destroyer as well. BTW, all the ships were still at 0kts and moured (sp?). I made SURE to set the depth on the stern shot as shallow as possible. Again, it went right beneath it. The trigger was set for influence and speed set slow. DID I MISS SOMETHING? I sure as hell wasn't going to surface and go after her in a shootout haha.

Well needless to say, the jap's must have woken up in their bunks to the sound of 4 torpedoes spinning away 5ft beneath her keel because they were PISSED!!!!!

I had ships, land cannons, patrol craft, and even a sea plane gunning at me. Luckily, it was still dark, drop the scope zig zag and make 3kts for the mouth of the bay, dropping down behind a land mass to hide my screw noise. I made it out no problem until i surfaced around morning time and a land cannon lit me up. Crash dive and cruise further on out. Crews had everything repaired in no time and I was off to file my report.

POINT OF ALL THIS:
--------------------

What am I missing? pistol, depth, moured ship, torp sailing right under her, calm conditions. Did I forget something? :hmm:

You missed... torpedoes running 3m deeper due to calibration and possible even deeper due to malfunctions. Try shooting a volley of 6 torpedoes, default settings, at no particular target. You'll notice they don't all run at the same depth. Some go lower than others.

As a "fix" for the Mk14 issues I often find myself loading out with Mk10s instead when I'm playing a pre-43 career. Much more reliable depth settings, even if they are a slower torpedo.

Oh, and try using Contact settings instead of Contact/Influence. I don't even bother with magnetic anymore because of how unreliable they are.

I was thinking the same thing. Plus, if you are going to ask people to do something to help you, the least you can do is be polite.

I guess manners really are becoming a thing of the past.

I blame the parents.

Inmy experience, atleast in early war (havn't gotten to 43 yet) with the mark14 the contact/influense switch workd the oposite. I've had torps set to contact, detonate perfectly 3 feet under the keel of sips, and torps set to contact/influence pass 1 foot under without detonating
