Deck Gun Aiming Problem
 

Since I installed GWX and SH Commander, I've had a problem with my deck gun. Sometimes it is wildly inaccurate along the horizontal axis. I put the crosshairs on the target and the shell will land far to the left or right... sometimes barely visable in the scope. Sometimes, the first couple shots will behave normally, then suddenly it will start missing. At first I thought this was just due to new modelling of the uboat's roll. I tried changing the angle to the target and speed... even dead stop in a nearly flat sea. Once it starts happening it doesn't seem to change, so it doesn't seem related to the action of the waves. (I prefer firing the gun myself rather than letting the crew do it.)

Other than that I love these mods.

Any ideas? Thanks

I haven't experienced this problem.
SH3CMDRhas a malfunction and sabotage feature, but if this happens all the time, it wouldn't be this.
GWX makes things harder, esp deck gun use. I don't know if this is a feature.
I rarely use the deck gun as after a contact, I try to get out of the area as soon as possible before the air planes and escorts find me and make my life hell.

Heya

I agree, it has been happening to me quite often although I am not sure if it is not the effect of wind? (wild guess)
At first I thought it was a bug when my shells were off to the right but then when it got really windy they started going to the left (after landing on target in calm weather for quite some time)

P.S: BTW Hello Everyone ;-) :p

Hello. :D

It helps tremendously, if you have an officer on the bridge with gunner-qualification...plus a petty-officer at the gun with the same qualification.

Well if ZOg's problem is just like the one I have experienced then it doesnt matter, I always have skilled officer and full crew using the gun (always a full bar)
And whenever it happens that shells land off the crosshair it is always the same fixed distance. So if a shot is off by lets say 2cm to left, every shot in the engagement will land at exactly that distance. (so after first shot you know where to aim)

Welcome aboard Kaleun Zog :arrgh!:

I think you might find that this is down to the movement of the boat....in GWX your guns are not automatically stabilised :nope:

are you using historical guns or guns that salvo?

often in salvo the second shot will be missplaced.

Jim's answered it right here.

The deck gun has been destabalised but no so much as you can't hit anything. Take your time, watch the movement of the crosshairs & you will soon get an idea of when to fire. They'll seem to be moving wildly but will then settle, take your shot then.

The longest shot I have managed in GWX is around 3700m and I placed 4 rounds below the water line along the hull on a large merchant.

I understand the OP's issue... it doesn't appear to be so much a stab issue. The up-down axis requires close attention - if you're firing at a range of, say, 500m, but the bow is pitched up in a swell, you'll likely overshoot, so you need to watch the barrel of the dg before loosing a shot.

The issue the OP is referring to occured yesterday to me as well, and does not seem to be stab related. I undertook the naval artillery training exercise to see if I could get the DG to work. While engaged, I ordered a turn to port to put a ship I was engaging off the starboard bow. When the DG returned to a 000 heading, shots took off at a 015-025 heading (roughly)... while both the sub and the target were sitting stock still. It almost appeared as though the gunners were correcting to avoid the bow net cutter & aerial... or they were using some Tiger Woods ball-spin-magic on the shell. In this case, I was targeting a large merchant, aiming at the stern (looking for that stern waterline shot) and hitting roughly forward of the superstructure at the waterline instead. At a range of roughly 750 m.

I'll see if I can duplicate my observations. It didn't seem like a stab problem, though... I'd had some time to become acquanited with the GWX dg... (GREAT WORK! The sound effects are awesome!), and this behavior (firing @5-10 degrees off the sight-line) only occured once, briefly, on shots over the bow of the sub.

Now, that said, I corrected quickly (a little Kentucky... err, Bavarian windage), but rather than deal with it, I changed stations quickly, then came back, and iirc, that seemed to sort it out.

I'll double check the next time a deck gun opportunity comes up, but it really doesn't seem to be a stabilization problem. The view through the sight seems steady enough. Once this behavior starts, the fall of the shot will land roughly in the same place in relation to the target. It doesn't seem to vary enough to be explained by wave action. Wouldn't waves result in shots falling randomly around the target, rather than consistantly 300 meters fore or aft? I can correct by shifting the aim if the shot falls within view, but sometimes this means cranking the site all the way to one side.

I don't have a petty officer or watch officer qualified in gunnery. In the stock SH3, even with qualification, the shooting was so bad, I just started doing it myself. Would it still help to have qualified crew when I'm doing the firing?

If you mean the DG pulls to the left or right while in zoom then this was in stock also
At times

Yes, I've had this as well, it pulls to left or right in varying degrees sometines as much as 10 degrees, for no apparant reason, no heading changes in the uboat, matched target ship's base course and speed. firing at it with the gun bearing roughly 300 degrees. I think it's a stock bug and can be very annoying when you're trying to hit a small target or a very distant one.

doesn't matter so much when firing at a C3 from 700m, it's bigger than the broadside of a barn, but when trying to take out a pursuing flower corvette at 5000 meters it's life-threatening:damn:

there is a hard coded miss factor built in to the guns as well. it will miss on purpose and be way off target at longer ranges. i've seen a shot to the bow then miss behind the stern when the target was at 90 degrees from my sub. i've even tested this on a dead calm sea and stationary with stationary target ship.

just something you have to get used to and expect to miss a lot.

Which means you guys must get closer to your targets.:|\\ BWAHAHAHAHahaaaa!:D

All due respect, Herr Kapitan, if my deck gun guys are missing a large merchant at less than 750m, on calm seas at midafternoon, I'm putting them in the torpedo tubes, where at least they can serve SOME purpose. At 500m, if they can't put an 88 through a porthole in similar conditions, I'm getting them a K.98 and putting them ashore... in Scapa.:D

Just cause you're Darth Vader doesn't mean we need to be saddled with the Stormtrooper School of Accuracy rejects. :)
