How did he do that?

[Phobus]

Hi, heres the thing.

It's 27 Dec 1939. I'm in square AM52, I've gone down to 120mtrs 0kts, listening, when I hear a warship; Moving slow, long range, closing, brg 332. Then I hear merchants closing as well. It looks like it might be a convoy. I'm ahead of it. I wait, then -

We're being pinged sir! next thing I'm taking damage and go down to 234mtrs before I get things under control, one dead.

Two thoughts occur to me. I thought the British DCs did not go below 350ft ( c100mtrs) and their asdic was only able to get an azimuth bearing but not depth until later in the war and its range was limited to about 2000yds in good conditions. Weather was 8m/s.

So how did he do it?

That does seem weird.

I have always suspected, while enduring a particularly nasty depth charge attack, that sometimes the computer just "poofs" a destroyer over head to make my life difficult.

One of the Anti-Submarine techniques developed between the wars was the charge and drift technique. Where the destroyer would steam head and then shut off the engines to "coast" along. Perhaps this is what happened to you?

Or the computer cheats

Do you know you were depth charged by the same warship you were tracking? Maybe your sound man was Bernard and he got "Long Range" confused with "right fricking above us". He has been known to make that confusion.

Or the computer cheats

Was your soundman rated? That does make a significant difference in the accuracy of the reporting

Or the computer cheats

While you were waiting for the convoy to approach, were you using TC? Injudicious use of TC can really screw up your chances of survival. Once I am engaged in the actual hunt, I rarely use TC. I have been killed many times by TC.

Maybe that wasn't just a nasty black stain in both periscopes lenses and basically at the same place and coincidentally with the same shape...

Maybe it wasn't a good idea to put all those glow in the dark stickers on the hulll....

How is this: you were
-not running silent
-doing more than 50 or even 100 rpm
-using TC
(I once got a beating when I went from 0kts to silent running in stock, that causes the boat to go to 3 kts (above 100 rpm) so I got detected BECAUSE i went to silent running)

of perhaps Bernard used the head and flushed a green cloud of sausage-ridden methane out of the bilge

What does TC refer too?

Angel dust; ever see what it does to kids?

Just kidding, it's time compression.

Ah, make sense now, I was trying to translate TC into a function of the actual sub operation. Thanks for the clarification.

[mbabbs]

Were you always at that depth or did the DD spot or hear you before you got there ?

For example if you were on the surface and then did a crash dive to that depth and switched off engines, an experienced crew may well know where you are.

Phobus; check out the first post in this thread

You didn't mention if your running GWX or not or what boat you had, because type IX will have a larger sig then a type VII for example. But there you will find I believe the answer to 'how he did it'.

I also would agree with any use of t/c near action usually results in bad news for your boat.

IMHO, you should never be out of sight of the DD's. They are best countered at periscope depth where you can see them and maintain initiative before sinking them. I just typed this for the post " Damn DD's or something so I make this quick.

1) Let him approach you at right angle

2) When his asdic begins pinging much faster ahead flank full rudder in direction he came from

3) when he passes ahead one 3rd full rudder opposite

4) let him pass towards your bow with a g7a on high spd, 2m 0angle

5) at 12 degrees from zero, fire as he passes the line. Practice until you get a feel for the effects of rough weather slowing his speed or an oblique angle away from your position, or range greater than 500m ( which will vary your aim point from 9-15). Oh yeah rudder 0 before you fire.

6) laugh as he sinks slowly, breaks in half or is immobilized to a significant or total extent. Not so funny NOW is it!

Works wonders on lone DD's, very well on two, and requires some imagination and a keen sense of situational awareness on three or more.
If you have it, Zaunkonig II is even easier.

Hope no one gets tired of me posting this method often,
thanks for reading!

1. What is zaunkonig? I thought I got shots for that when I was in the military!

2. Good hints should be posted often. A good hint, running silent in the forums, does no one any good

[kaarlo]

When the escort is approaching, go ahead flank away from him (periscope depth). When she is exactly behind you, and the range is about 500 m, and he closes in to kill you, fire one fish from the rear tube. Depth should be 6 m. Watch closely as the eel goes under the escort. BOOM!

Not very realistic, but very satisfying when you have seen enough of DD:s for one day
