Long story short.

The sub is electric and only uses the diesel to recharge the batteries.
If it is sailing faster than the diesel can recharge, the battery will drain.

My reading seems to show a very uneven upgrade process on these WW II leftovers. Even within the same class not all of the subs received the same upgrades. To really make a correct set of numbers requires research into the individual subs by name. If you read articles about the actual Segundo it ...

So this link:

Shows the original Balao class as capable of 20.25 kts surfaces and 8.75 kts underwater. And the max. depth of in game sub is much greater than 400 ft. Probably because the "collapse depth" was reputed to ...

From everything I looked up the Balao should be able to go 20 kts on the surface. I've already reported that problem.

The best way to handle that IMO is to send a message to all players that someone has proposed to go to X speed. If the other players agree than the game speeds up / slows down until a critical event of some kind (new detection, etc...) sends it back to 1x speed.

I reported this same issue a long time ago, but the developers weren't able to replicate it. Maybe they'll find it this time.

I'm taking everything I read about this whole conflict with a grain of salt. You have to remember that disinformation is part of any intelligence plan in a war.

The only thing that would worry Ireland is a threat to attack the Guinness Brewery, otherwise they have little to worry about. Love it there. I'm going back some day.

Awesome

New Surface Contact and New Underwater Contact are the only two I have set to push it to 1x. So, your question made me do another test and I found a clue(s).

If I turn off every single flag to go to 1x in the message log options it continues to run at full speed until a pop-up about a new radar ...

I'm playing a scenario called the Enemy Below in the Silent Service DLC. I understand the game can drop out of "fire" and "double fire" speeds to 1x if some calculations need to get done and cannot be done when the game is running high speed, however, shouldn't go back to high speed automatically if ...

Ah, but those stats seem to refer to the Balaos as they served in WW2, are you sure you're not looking at a DB entry for a Post-War GUPPY conversion Balao class?

Those configs would have made them somewhat faster underwater, with the removal of guns and smoothing out of exterior surfaces.

I ...

The sources I've seen on the internet all seem to say the top speed of the Balao on the surface was 20+ kts. In game it's 18 kts, plus it burns batteries at top speed on the surface or snorkeling which I don't believe is correct. Also, the published cruising speed is 10kts, but in game it is 8kts ...

I've been playing the "The Enemy Below" scenario in the Silent Service DLC and it seems that no matter how close or far you are from your target straight running torpedoes (MK 14) always have a PH of 40%. This seems wrong to me. Shouldn't this change with the distance from the target and the angle ...

I did a search and can't find anything other than PBEM.

I worked on a game a long time ago and we were getting unlikely results far too often. While I can't say it's true in this case I can tell you that random number generators in software can have problems. Good random number generation for applications where it is truly important rely on a hardware ...

<t> I got through this one by using the ESM mast to find the enemy ships and squeezing through the gaps in their coverage. Once I was close the area to scout I stuck VERY close to shore to take advantage of the sonar "clutter". Moving slowly in the layer and having patience in the trick in this once ...

<t> One thing that could help is to fire torpedoes at the ASW ships as well as the "real" targets as the same time. Even bearing only launches with active sonar warheads are good enough and you might even hit something. Forcing the ASW assets to dodge your torpedoes while you are busy running away ...

The trick is to hide behind the little islands and spitz and use individual "spotters" to find the Soviets. You then fire your missiles from radar "shaded" positions.

<t> I don't think the problem is the subs per se, but the AI that "runs" them. Based on my experience with the Silent Service scenarios I really can't see any way that an AI that is less intelligent than a human could get into torpedo range of any surface group with a decent ASW capability. IMO, the ...
