How to survive ??

Chisum · 07-27-08, 03:17 PM

I know it's a suicide to attack a convoy in 1944 but as is my duty, I try anyway.
But...
But when we fight against a weapon devastating like this on the picture, can you tell me how can we survive ?

The first attack...

...is fatal.

R.I.P. my friend

Development of hedgehogs is number two in my list of evil anti-sub creations after improved sonar

Fire from long range and take advantage of FAT eels

And dont get caught

all you can really do is go as deep as possible and listen for the splashes... at the first hint that hedgehogs are in the water go ahead flank... maybe turn. a lot of it has to do with luck and avoiding detection in the first place.

hedgehogs sink quickly, and its difficult to manuever out of the way quickly enough to evade them, but i recall an occasion where i managed to evade about a dozen hedgehog runs before they finally got me so it is not impossible.

im not sure on the historical accuracy of launching a full scale assault on a convoy that late in the war.

single ships and targets of opportunity were the order of the day really... byt late 1943 convoy attacks were nearly impossible to survive.

One tip for evading a hedgehog salvo...
crash dive... and I mean DIVE... straight down if you can... bow to the bottom / stern to the stars!

It makes a much smaller target profile. :rotfl:

The best solution for escape is to pull out the pc voltage plug and run away from home

Sorry, my friend. Fire from long distance.

U-46 Commander · 07-28-08, 02:02 PM

when the real u-boat captains were faced with this, they had to fire from long range. Also try to get ahead of the convoy, dive deep-50 meters, and slow to 1 knot or so.(silent running). wait for the escorts to pass, then go to periscope depth, sink afew ships, then get out of there!

strategic use of decoys...

What i have done in the past is launch decoys in the following manner.

While diving after the initial attack start a 270 degree turn, release a decoy every 45 degrees of heading change

lets assume you start at 000 degrees

here is the procedure

order a depth of 220 meters
start a right turn
rig for silent running
at heading 045 - launch decoy
at heading 090 - launch decoy
at heading 135 - launch decoy
at heading 180 - launch decoy
at heading 225 - launch decoy
at heading 270 - launch decoy - stop turn - continue dive to about 220 meters

this will create a descending spiral of decoys... the destroyers will be receiving seven echo returns when they ping... 6 decoys and 1 u-boat. this forces them to decide which return is the actual u-boat and then attack it... they have a 1 in 7 chance of selecting the right target... hopefully the selected a decoy instead of your boat.

sneak away at 220 meters depth making gentle 15 degree turns left and right.

never increasing speed never surfacing or never securing from silent running until you are sure you have escaped.

the problem with this strategy is you use up pretty much all of your decoys in the process, but you can refit at a supply ship.

I don't know.. Once I tried this tactics, but leading escort sweeps the area pinging frequently so it didn't worked for me

Wise

"sneak away at 220 meters depth making gentle 15 degree turns left and right."

is this gentle zigzaging really necessary ? slows down a boat a little though :hmm:

Do DC have a maximum deep to explode; i mean, can you avoid them at certain depths or you are not safe even below crush depths :rotfl: :rotfl:

300 meters if memory serves.

DCs just vanish at 300m

As far as the gentle zig zag... i dont know if it really helps or not

I like it :rotfl:

Always try to keep an eel loaded in the stern (two if in a IX)....the escorts always slow to 10/12 knots to get a precise fix.

A Falke later in the war is often your best friend....but remember, they take an extra 100 metres (400) to arm.

Chisum · 07-28-08, 06:45 PM

Fire long range...
Ok.
But the problem is that they wan't !
The escort is increasingly close to the convoy and force me to stay out of range of fire...(this sentence has been entirly translated by Google, I'm not sure you can understand lol).
And if I fire an acoustic topedos (T5) after 400m she follows the nearest destroyer and never hit a merchant...

Thanks to your ideas, I like the spirale system and try it next opportunity.

PS: to all players, don't forget: maximum depth is estimated with 100% integrity hull ! If lowest...maximum depth decrease(unknow values...). I can just tell you that with 30% integrity hull my IX/D2 had imploded at +/- 250 meters...
Last screen taken at 249m:

PS: note that the official values found on google says max depth at 230m...
