Sub Diving Times

[CaptainChunk]

This may have been posted before, it may not have, but it seems to me the American subs dive consistently slower than their German counterparts in Sh3. Calm waters seems to be about the same time but in choppy seas the American subs just take forever to get underneath the water. Plus, sometimes the entire boat will be suspended above the choppy waves (has nothing to do with frame rates) and that seems to impede diving times as well. Anyone notice this or am I completely off my rocker?

Agree.... crash dive in my Tambor seems more like "get under the water before that plane makes a 2nd bomb run"..... JIMMINY they are S L O W to dive.

Is this historically correct?

American subs did dive slower than German ones. They were able to get away with it since radar came into widespread use on US boats.

Atleast now there wont be anymore complaints about the dive times of type 9's :D:D ,its no wonder american boats were called "Pig Boats" ;)

Holy smokes.... this is going to be a short war for my 1st career if they keep sending me just south of Honshu... those Jap airpatrols are MURDER. :o and with a dive time of ...ohh say 60 seconds, I wont last long.

<<<<< gets out dremmel and starts drilling holes in bulkhead :)

Edward Beach, said US boats could dive within 30 seconds when the crew was experienced and trained-up. How long is it taking you to get below? I don't have the sim yet, so I'm curious. tnx.

Wierd, my S-boat seems to go under in about 15 seconds on Realistic. I tried a Gato and same thing. I was going to post something earlier as it seemed a bit arcady.

[AVGWarhawk]

The older S boats dive quickly but they are slow on the surface.

:dead: My Gar class takes at least a minute to go under.

It is true the US Fleet Boats had slow dive times. Be sure to keep you SJ and SD RADAR's up and running when on the surface. The surface times are also accurate.

The Dive time is correct it seems but once submerged it goes way off
IMO .It takes no time to get to 160 or back up to periscope level.

[Cmdr Mathias]

Yes but remember this is a 312 foot boat. A tremendous amount of flooding in all spaces needs to take place just to iniate the dive.

I agree, depth control seems exaggarated in SHIV.

As for the dive times, I find them accurate and occasionally varied enough, too. Keeps you on your toes!

[CaptJodan]

Dive times do seem about accurate to me. I know some people were also thinking the surface times were wrong, but they definately look right (watched the real thing do it in "Run Silent, Run Deep" last night, was like watching the game).

Actually, I was wondering whether the American boats really had such great depth control. The boat can really move in the vertical once it's under as far as I can tell. More than any of the U-boats.

Also, and I think this is a game thing, but the boats seem exceptionally stable in rough seas underwater. The boat doesn't seem to rise and fall like in SH3.

But yeah, I was wondering about the underwater manevuerabilty there in the vertical.

[QuillOmega0]

Dive times were slow for American Boats, because of how the vent valves operated, while the Germans had what I believe were flaps to expel air faster out of the ballest tanks, as it didn't have to go through a puny valve.

The Americans used a valve contraption that didn't expel air as fast. Of course this is just my theory :p

EDIT: augh correcting mistakes

[tedhealy]

Don't forget diving by ordering periscope depth versus crash dive will give you different results...crash dive being much faster of course unless you already are at flank speed.

[Faamecanic]

I'll have to time my Tambor class on a crash dive. I SWEAR it takes 35-50 seconds just to get my sub under the surface. NOT good when the Jap airforce is very active. And that is with me cruising at 12 kts Stnd speed BEFORE I issue the crash dive order :o
