So that's where those oranges are for.

No no NO! You have to save the oranges for the U-boat special cocktails!:yep:

I would stick to official BDU doctrine:lol: , it saves your food:rotfl:

Yes and it works very well if you have the correct data :up: The main reasons for not using large Gyro Angles were two:

1.- More difficult firing solution, specially more dependant on the distance (You are taking bearings and calculating from the scope or UZO, which is in fact some 40 metres behind the Torpedo tube:88) so the torpedo must have a convergence and cross the line of sight of your UZo/Scope at the distance you estimated your target is. Failiure in distance is then fatal as the torpedo is aimed incorrectly).

2.- Chances of the torpedo not turning accurately, either by mechanical failiure or simply by currents or rough seas deviating it.

90º/270º is however much better than anything intermediate for both the easyness of the firing solution and the tactical possibilities it offers. Specifically, it is a wonderful shot when you miscalculated your approach or the target zigged and you would be too close if you stay in perpendicular course. Changing direction to a paralell course (Either same direction for bow shot or opposite for stern tube shot) ensures the distance to target at the moment of shooting will no longer increase :up:

I heard this story! That was incredable.

I like to get out in front of the Allied Convoy and sit still. During this time I use the ruler and plot tools to locate and plot most of the ships from the convoy. After the lead escort closes within 2000m, or round-a-bouts, I take a look at him normally not raising the scope but as low as possible. I try to torpedo the lead escort first, then I have several minutes at high speed to move in and make a un-molested attack on the convoy.

After getting in, if the convoy doesnt scatter too bad, I use the merchants as screens against the escorts to reload my torpedoes for another attack.

Caution though: This method means certain depth charge.

HUZAA! :arrgh!:

This is especially useful in fog condition when all you have is the hydrophone and a parallel course.

A tactic I've used a few times, and one that I am beginning to favor a lot is this.

1) Lying off wayyyy ahead, and about 1000 m outside the track of the outside column (call it Column 1), with bow aimed between what I calculate to be midway between the last ships in Column 1 and the column beside it (Column 2). I set depth at about 80m and speed at 1-2knts, silent running of course...

2) When the lead escort is just past abeam, I go to 3kts and aim for 15m. Once I have some momentum, I will drop to 2kts, but I am aiming to come up about 100 m inside the Column 1 track. Just as I hit about 30 m, I set rudder slightly to port or starboard (as appropriate) so that my bow will begin to come "up the line" of column 2.

3) All torps are set for magnetic, and I have already dialed in for depths of 11. T2s unless it's choppy sea at night.

4) As soon as I can break scope, I take the last big thing I can see down the line on Column 2. Adjust depth of the torp. Go. Give a little rudder if needed (drop the scope, too, if needed), up scope, take the next big thing (or even a small thing if the set up is A1, which it should be). And then again.

5) I stop at 3 shots. I fade to black... I aim low at 3 knots to get some mo' to about 80m, drop to 2knts and either come back dead under Column 1's track or over to Column 3's track, then head out the back.

6) Results are mixed. So far, on 12 3-shot runs, I've scored 0/3 (2), 1/3 (2), 2/3 (7), and 3/3 (1), mostly big ships (pyro, large tanker, large merchant, whaler). By "score" I mean "sink" or "cripple" so that the convoy leaves them.

I know it's conservative, but it puts us on the scoreboard just about every time. On our boat, our watchword is:

2 weeks of "Be more passive" 0 tons, but alive
+ 2 minutes of "Be more aggressive" 33,000 tons, not dead
= 33,000 tons, alive

PS: I'm doing this AFTER T2s become reliable, and am using GWX 1.03.
PPS: I'm not very slavish about the gyro angles... as long as I am within 330-30 degrees, I consider the shot "takeable", though I wait if I can.
PPPS: Sorry... one more key detail..... detection rates are high, but (my) escapes are good. On 12 runs, I've been pinged on 8, DC'd on the same 8, but, running low, slow, and "I belong here", have taken only "fender benders" for damage. But this is all pre-May 1942, so I know this won't last.

I've found a new method that requires no munitions.

I just attach a picture of hillary to the attack periscope, most free/allied shipping self destructs.

Be forwarned however Russian ships, at the time being communists will be attracted to you like flies.

:rotfl:


I've yet to come across a convoy (early days yet.. and I need to get outta the dock some more), but I think my first few tries I will incorperate the 'Blind Mans Bluff'.. sit about 2kms off the side of the convoy at roughtly a 90 AOB in about 200m of water.. use hydrophons to assume they're pretty much infront and unload all tubes.. slink away and hope to maybe have some numbers when return to dock.. I'm sure it's the safest way to do it.. :smug:

Question.. if you're in the middle of a convoy after an attack.. how sucessful is hiding underneath a merchant (I literally mean hiding.. keeping his speed and sitting about 50 meters directly beneath him)? Obviously the escorts will have trouble DC'ing you if you're crusing directly beneath another boat..

Deck guns and torpedoes firing with aa guns shooting at the deck guns of the escorts (i always choose the biggest aa guns)

fights in 1944 with nygm 2.6β and does not sink nothing.........:damn: :damn:

Standard attack against convoy is
a) postion sub on estimated course of convoy / slightly to the side
b) dive/sneak between escorts in front of 2 promising ship lines
c) on torp per ship
d) deep dive /escape in 135 degrees away from convoy course
e) reload and kill all trailers

f) if fuel permits and convoy course is plotted, repeat with a)

With torpedoes.
