Deck Gun Aiming Problem

[Zog]

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

[irish1958]

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

[Paajtor]

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:

[Mush Martin]

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.

[Zog]

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?

[bigboywooly]

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

[KeptinCranky]

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. :)

[Canovaro]

I too experience this issue.
Sometimes it is way off and other times it is very easy to hit.
Often I let the crew fire because my shells are flying in all directions.
Sometimes being at highs speed makes it easier, sometimes it makes it worse.

:doh:

You might want to consider going back to the coconut shy at the fairground for a bit of practice if that's the case :rotfl: :up:

the experience level of your crew does have a small, i repeat, small effect on accuracy but they will and do actually miss at 750m sometimes. they give you one shot on target then one out in the boondocks so the hardcoded AI hit to miss ratio is reached to simulate realistic action on pitching deck under fire even if it is flat calm. if you notice at 750m or less when they are hitting you will see a bow shot then a stern shot because they are trying to miss but the damn ship keeps getting in the way lol.

i never let the AI shoot for me because it just wastes all your ammo so man the gun yourself.

HI
Currently suffering quite often for the Deck gun shells landing too fall on the right of the aiming point, even in good weather conditions (calm see).
Yesterday, I was 700m from a ship, but the shells landed OUT of sight on the right..... No horizontal or vertical roll of the sea influence....it was pretty calm and I kept the barrel of the gun under visual control when firing....

GWX 3.0 + SH3 Commander installed.....

Did anybody find out a solution to this annoying problem of deck gun inaccuracy?

THANKS!

[magicsub2]

the thing to do is to get REAL close to the target, say 300 m and then while your deck gun crew blaze away, use the flack gun.

Are you fireing yourself, or do you let your crew do the job?

I'm always fireing manually and never spotted a problem like that. Before that, I let my crewmen do the fireing (but that was before I tried GWX) and there were some problems like that. I think they got too much Becks at the harbour. :03:

Kpt. Lehmann I didn't realise you can be a No.1 :yeah: :D smartarse :D :har: :har: :har: :har: and I can tell you've been training your own deckgun :03: :O: :O:

I'm firing manually of course.
The shells land always on the right side of the aiming grid....problem is that they land very far on the right....sometimes it's almost impossible to hit the target even at close range.....
If you imagine the drawing here below as the aiming grid ( "X" is the center, the aiming point), the shells fall usually around the place marked with "A", "B" and "C"

.................................................. ......A A .................B B B ..........C
|---|---|---|---|---|---|---|--- X ---|---|---|---|---|---|---|---|

When I got distorted firing towards "A" I am able to compensate manually with success, but when it comes to "B", it's hard on close targets and impossible on far ones....I completely lose the opporunity to target specific points of the enemy ship......Some other times, it is even worse....when "C" is the point where the shells go to, I am unable to hit anything....even if I unzoom..........
CAN SOMEBODY HELP ME!?

:damn: :damn: :damn:

Is it possible that even thou your cross hairs are on the target that you did not wait long enough for the actual deck gun to rotate to that position?

Thanks, but I am NOT using ALL WEATHER GUN mod....(unluckily!)

No, I don't think so....I keep having the shells landing far from aiming point (which I a meant through the binocular of course) even if I give the deck the proper time to align.
A further confirmation is that if a fire a shell which lands wrong, I have to wait for the un to reload, so the barrel would have the proper time to align....but the second shell always lands as wrong as the first....

I can bet is not a gun alignment problem.....but THANKS for guessing!

[variellone]

well.....seems I'm the only one to suffer from bad guns coming out from the German War Factories.... :damn: :wah: :wah: :damn:
Please help!

[Hanomag]

Maybe its time to apply some "Kentucky Windage"? :hmmm:

Lead the target maybe...?

Whenever my shells fall forward or aft? Of a vessel I just adjust fire till I score hits. In other words aim at the open sea and if the shell hits ..fire for effect. :arrgh!:

But I have had the issue with my shells falling aft or forward of a target. It varies from near misses to the extreme. This does not occurr with every gun engagement for me though.

Possibly its the speed that the ships are travelling at, plus the distance. Maybe change you reload time witn commander and use rapid fire to adjust your aim easier?

[kenijaru]

well.....seems I'm the only one to suffer from bad guns coming out from the German War Factories.... :damn: :wah: :wah: :damn:
Please help!

wasn't there a whole batch of K98 with bent barrels (or was it bent sights?) that came form a factory that used slave labor?
its some sort of... ultra-realism feature :|\\

but yeah, sometimes my shots land a few cm to the left of the crosshair, and when i correct it... they land a few cm... TO THE RIGHT... but luckily only happens once or twice in a while.

[Murr44]

I try to place the sight a little to right or left of the target & observe the splashes, making minor adjustments until I start getting hull & waterline hits. Had an experience the other day where I torpedoed an unarmed medium cargo with my last eel. We surfaced in 7m waves & came along side the ship (about 500m away) slowest speed possible. Proceeded to blast holes in her side until my aim started being thrown off by the wave action. Accelerated to flank speed, pulled a "U-turn" and came along her undamaged side to blast a few more holes. It was a little time consuming but eventually she went down.

The problem is that the aiming misalignment I'm suffering is sometimes so strong to completely prevent me from hitting the enemy merchants event at vert short ranges...
Furthermore, I don't use the MOD that lets you man your deck gun with any sea condition....7m waves seem too much to man a deck gun on a sub in the middle of the ocean, but that's MY point, anybody is free to enjoy the game as he likes!

Anyway my problem IS NOT CAUSED BY SEA CONDITIONS.....
.........so I'm still looking for help....
