Torpedo trouble in high sea states

Sea Demon · 08-24-06, 10:15 PM

While playing in an Akula-I SSN last night, I had hunted down a Spruance Class DD which was part of a 2 ship SAG. The Sea State was very high, and I was at a range of 5500 meters. I attacked using two wire-guided 65cm torpedoes. The Spruance ran away at flank speed (33 knots).

As I raised the periscope (with an evil grin on my face :p) to watch the results of my successful track and targeting, I noticed that the Spruance had travelled out to around 15,000 meters and there appeared to be two dolphins jumping out of the water behind the Spruance. As I increased magnification in my periscope, I saw that my torpedoes were jumping out of the water and were losing speed in doing so. Basically, my torpedoes were not going to catch up with the Spruance. Eventually the Spruance outran em' and they were gone. It was OK though, as I launched 4 SS-N-27's from my external tubes, which resulted in a timely death for the Spruance.

Is this torpedo behavior normal in high sea states? Or is this something in the physics model that may need correction? (ala Patch suggestion thread)

Sea Demon,

I have noticed that too. At higher sea states. I dont believe it to be a problem with the game. It is your torpedo setting usually. If you left it at the default ceiling setting of 10 and your seastate is 4 to 5. The problem lies in the troughs of the waves as the wave moves the water is deeper than your torp setting. so the torp comes out of the water and hits another wave until it becomes unstable.

I have remended the problem by setting the ceiling to 15 ft which is still good to kill almost anything.

It may very well be a game issue. But I dont like saying the "B" word.

Thank you Seadawg23. Yes, you're right. I was using the default ceiling setting. It does make sense that adjusting the ceiling down a few feet would correct this. Can't wait to try it later.

I appreciate your advice.

Success.

For those of you who may have seen this, Seadawg's advice was spot on. This time I used 2 MK-48 ADCAP's against a Kirov in high sea conditions, and I set my ceiling to 15 feet on one and default of 9 feet to the other one. The one at 9 feet showed the problem, while the one set to 15 feet went on and blasted the Kirov.

excellent!!!! thank you Sea Queen.

for giving me the Cudos...I dont claim to be all knowing...but I know some...

Seadawg23 · 08-25-06, 10:04 PM

Sea Queen....what was the SEA STATE??? I presume 4....I did not know you were attacking a Kirov.....it draws 16-18 feet... SO!!! if sea state 5....15 will work depending on a few things, the range...as per your post 5500 M...maybe NO dice i would think: u got lucky@@@

look at it this WAY:
Sea State 1: FLAT you can set torp to 5 if u want...all good!!
ST(for now on sea state): 2: Alittle ruff....waves 2 ft approx: Default 10 feet good

ST2: see above...NO concern waves about 3 feet or 1 meter

ST3: if....i have seen... Torps bounce with default settings....Only if!!! pay attention!!....you are shooting perpendicular or 45 degs give or take 10 deg on the WAVE trough!!
RARELY....will you see a true perpendicular shot...up to 10 DEG either side depending on depth!!! CAN cause torp jumping!! OFF TOPIC!!! a SUB launched TORP will HOLD the DEPTH of FIRING sub...UNTIL enable is ACTIVE..... SO VERY IMPORTANT!!!!!

A SUB at 1200 fl....launches a ADCAP:: look out!!!

Range to Enable: 10000 yrds(((( DEFAULT)))..USE,,,NAVMAP.RANGE CIRCLE..HYPOTHAEICAL(SPELLING)to ====
Ceiling: DEFAULT: 10 FT...TIS CRAP!!!! SET TO 20 FT!! why??? periscope depth is 53 ft...688(i) USN...you kill all subs...they within min/max SET ALWAYS...set enable TO MIN OF 2 nm(or 4000 yrds) srry yell...typo!!!

Range to Enable: 10,000 yrds( can adjust= TMA for new solution) use NAVMAP...to see...UPDATES!!.!( = 10 NM default)
Set Ceiling: 20 FT( AI....at 10 feet)
20 ft should hit ALL SURFACE minus fishing boats ...CIVILIAN Cruise liners and UP...YES...a civilian tanker/cruise...draws 16 ft water U WILL miss on torp shot!!!
Set MAX depth...vs: AI to 200 ft....rare for them to dive DEEP. on 1st torp....set next to default MAX depth... WHY? launch 2 torps 1 will miss..

LALALA...i can g oon and on...replies!!

that is all....look for more after

Thanks for the follow up. Yes, I setup the scenario with a Sea State of 4. I still have to try a Sea State of 5 at some other point and test out some other settings. But yeah, 15 feet seemed to work OK. Kirov was hit just fine. This time the target ship was at 8,000 yards. And he turned to run away on a parallel course to my torpedo at flank speed.

But if 20 feet works, that sounds better. I would rather have a setting that is further away from the surface in this type of Sea State, and still connect to the keel of a ship.

Edited to add: Oh yeah. And I'm Sea Demon, not SeaQueen.

Oh good... I can't tell you how puzzled I was over that one. :-)
