Invisible at night desks awash!

MarkShot · 06-08-07, 08:15 PM

SH3 1.4b/GWX 1.03

So far, I have been doing submerged attack practice runs and have a fair feeling for how detectable I am.

I decided to research detection under night conditions with a custom mission and the stealth meter. Here I approach a Tribal Destroyer at 3KTS decks awash (7M); calm seas. As you can see, I am quite literally invisible. I have approached within 100M and only a love tap from the flak gun will get its crew's attention. Until radar makes its appearance, I imagine this is going to have nasty consequences for convoys.

Submerged they can pick me up around 1000M in calm seas. Awash I am a ghost ship. This means that I can strike with impunity. Even if everyone is armed, it doesn't matter if they cannot see me. I can dive to escape after attack. However, it is more likely that I can simply creep off until I break 3000M. At which point, I can right up 18KTS and pull away rearm.

It's going to be a turkey shoot.

Screenshot from the awash test.

Thanks a lot for the info.

Got to try this right away.

In real life, quite often the only way a sub was spotted on the surface at night was due to excessive speed, or an attempt to dive. It was quite normal to be passed by an NME vessel, unnoticed. As long as the captain kept his cool, the U-boat was usually quite safe.

Yep decks awash has been mentioned before as the way to conduct night attacks
Your profile is lower and as long as speed isnt excessive they dont know you are there

Once passed a Br DD at about 200m
We were on converging courses
I missed the " ship spotted " as was out of the room
Came back to see him steaming merrily past

groundbreaking stuff imo

KeptinCranky · 06-09-07, 07:10 AM

Okay, I've tried this too, been quite succesfull but that picture is ridiculous

:rotfl:

The first time those guys on the destroyer will notice your precense is when they've litterally plowed into you and are sinking as a result

I mean, green crews, possibly, sleeping on watch, maybe, it being trafalgar day and the whole crew being drunk, only on a specific date....but damn, those guys should be able to hear your diesels going chugga chugga...gurgle....chugga chugga... everytime the exhaust gets flooded.

well... i was fully surfaced when waiting on a convoy...
it was dark and good weather (0 wind and such)
when the convoy poped up (bernard was late again) it was a shock...
as a great horror to me it was a convoy with hunt III DD's and a BB in the midle...
was to late to do a crash dive or trying to escape... so i said "well men... it was good to know you... blablabla" and awayted sudden death... got thirsty and went to the kitchen to get a coffee... when i got back i almoast fainted when i saw the convoy was passing me... i was in the middle and no one spotted me

. even the crew of the BB (wich hit my bow and just sailed on) didnt see me ...when safely out of distance i repaired my sub and continued the hunt...

Speaking of ridiculous pictures!!! Have a look at your avatar :rotfl: :rotfl:

I made that as a custom mission with a veteran DD crew.

The reason I pointed this out is that I also find it kind of bizarra that you can literally close to boarding distance in this mode. How is it that if the boat is 1M deeper running electric that they can pick me up at 1,000M, but 1M shallow and running on diesel I have the stealthiest sub that ever sailed?

It does seem a bit over the top to me even though early war attacks were at night on the surface. Oh, please don't shoot me, but I am going to mention AOD again. Night surface attacks are big part of AOD, but you don't just waltz passed the escorts, you need a moonless, overcast night, and heavy fog. Then, you thread your way through the screen between escorts. You don't see them and they don't see you. Of course, there is always the peril that you will run right into one of them 500M off your bow.

So, what do the SH3 veterans do about this super stealth phenomena? Exploit it until the escorts get radar? Attack submerged and give the AI a fighting chance?

Thanks.

What depth do you guys set for decks awash so my watch crew doesnt go below decks? 5 meters?

Kaleu. Jochen Mohr · 06-09-07, 10:14 AM

7 meters...

@markshot. whats AOD ?

a supermod ? or a stock version ?

bigboywooly · 06-09-07, 10:42 AM

If you run decks awash with crew up top you are using diesels
The game doesnt allow you to use electrics on the surface

A 16-year-old game, still widely regarded as the best subsim ever.
