rough weather attack

unterseemann · 06-12-09, 06:10 AM

Some are complaining about the bad weather and the difficulty to get a good solution for a torpedo shot.
First, learn to love bad weather as it will help you approaching convoys especially late war. Escorts are far less effective in heavy seas...
Ok so the main problem is the poor visibility: If you expect a classic 90° shot you may not see your target or if you see it distance may be less than 300m and will result in dud.
If you want to attack a convoy, you will get in front of it and have an idea of its course. When the lead escorts have passed and not detected me i try to get perpendicular to the convoy course. When this is done i check my hydrophon and try to get a contact in the 270-280 or 90-80 and keep it in this zone ( by moving forward or backward)

In that photo, convoy is heading east and i got it in my 280. This means that at one moment it will cross just in front of me so i will have it in my periscop

As soon as i see it i order a parallel course to it

I will let it pass ( be careful about collisions) next to my sub. Even if the ship is very near it can't detect you

So now you're behind it. Your goal now is to get REALLY behind it. It's not the case in the photo under but you need very light course modification to reach this goal

I ussualy do a salvo shot if visibility is poor and there's a convoy.. Most of the time it ends with at least one hit.

During this time you will identify the ship and set your torpedo. Go to the torpedo room, set to magnetic trigger (never impact because it will bounce against the hull) 1m below keel depth, switch to manual input, check in your crew screen that a weapon officer is ok and open tube door.

Go back to periscop view

After light changes

Ready to shoot

As you are now in the column be careful about what should come behind you

Close call...

Torpedo impact! The advantage of this method is that when you shoot your torpedo, enemy vessel is in visual range and as he is moving away your torpedo will need extra time before join it. This means you can shot at 250-300m only. I use T2 torpedo running at 30kn, if my target is 10kn when the torpedo runs 300m the boat runs 100m so the torp has a 400m (minimum) course and will explose.
I know magnetic triggers can detonate prematurely in heavy seas but it happens very rarely to me

So now you got a empire freighter in front of us, pb is that it will zigzag but in the meantime it will give a larger target

It's going starboard
Instead of a 0° shot i will aim the bow of the ship to ensure a hit. Go to torpedo room, change the bearing to 4°, keep the AOB at 0, open tube door as usual

Fire your torp

Now escorts will try to catch you. Put a mark on the map

And get away depth 190m, course north, silent running. Damaged ships in rough weather easily sink, just wait for it...

One ship is sinking! Escorts have not detected us so far

Both are sunk, attack successful!

Who's the boss now?

Very good Sir! As a fellow 100% DID player I'll definitely study this method further. Thanks for sharing
