Torpedo salvos

[fisherstoys1]

Hi there
Question today is getting your torpedoes to not hit the same spot.
I have tried the salvo but I really dont get much in response.
Is this because you cannot select the tubes to salvo or do you set the spread and then fire you fish.
I am running Opmonsun on its own right now,
it has been great to have one Atlantic fight and a secound Pacific side. The prime double agent.

There is something else I noticed that the US torps are much less effective than when I was runnnig just 1.4.

The US did not have a salvo option, they fired torpedos as individual shots.However, there are two methods.

One is what was the traditional.Say you want to fire three torpedos at a mid sized freighter.For max coverage you fire one at middle of target(MOT), one forward, say a forward mast, and one to the aft area.Find range and get a bearing on middle of target(MOT), send to TDC and FIRE1 Then using the spread knob on the TDC, adjust it the appropriate degrees forward(which would be starboard in this example situation if attacking from starboard side at a 90 degree angle, if attacking from port then would adjust the knob to port to send the fish forward of MOT, obviously) The number of degrees forward of course depends on length of the target.After adjusting the knob, fire two.Then adjust the knob a few degrees in opposition direction and FIRE 3 to send torpedo to target.May take some practice but this works and from my understanding was the more traditional method use by US subs, esp in earlier years of war.Of course make sure the PK(Position Keeper) is on as it keeps the bearing, range , and AOB updated.This was the major advantage US TDC's had over other nations.

The method I use is different and I find it more accurate.I got the idea to use this after reading Admiral Richard O Kane's books about his time on Wahoo and the Tang.Under Morton on Wahoo(and later on Tang under O Kane) shots were fired using new bearings.So find range and send bearing for middle of target, FIRE 1.Then move the scope crosshairs over the forward mast, send new bearing, FIRE 2.Then move crosshairs over desired point aft, FIRE 3.The torpedos really are aimed as individual warshots here.

Hope this helped.

I do about the same as Bubble, cept I fire forward to aft.

The other method that works well is to fire by the wire as the ship crosses, basically a 90 degree OKane attack, but you can do the same with the stad, get the same info you normally would by stad, then set a bearing in front of the ship, unlock PK and shoot the spots you want as they cross the wire.

Hmmmm, now I've had some of my best spreads firing aft to bow.

That's usually what I do. Read somewhere it's harder for the target to evade all the torpedoes if they are traveling in a divergent spread.

(a) Divergent Spread
A divergent spread is a spread in which the torpedoes of a salvo intersect the target's track at different points along the target's length and at different torpedo track angles. This type of spread is difficult to avoid because of its fan-shaped pattern. (Diagram A, Plate XV).

(b) Longitudinal Spread
A longitudinal spread is the spread obtained by firing a salvo of torpedoes along identical torpedo tracks. Torpedo #1 hits the target at A, #2 at B, and #3 at C, due to movement of target across the identical track of the torpedoes. It is a simple type of spread, having the disadvantage that the target which can avoid one torpedo track undoubtedly can avoid the others which are following in the wake of the first. (Diagram B, Plate XV).

The first is a Middle of Target, Stern, Bow spread, as opposed to an Aft, MoT, Forward spread, but it illustrates the point.

Longitudinal spread may be difficult to acheive when the Position Keeper is on, right? Since the target's position will be constantly updated. I think that the skippers that rely heavily on the TDC and PK may find it easier to use the spread option, to hit diferent places in the target. It has the advantage of allowing you to calmly set diferent angles and fire, as the TDC/PK will be constantly keeping up with the target.

Now, those crafty methods come in handy when you have, say, a damaged computer or an u-boat on your hands - specially so with u-boats, as it's computing device is archaic and its accuracy decreases seconds after you made an gyroangle estimate.

I guess I should of this coming!

Sorry to be rude, but a quick lesson in the Queen's English: It's "should have", not "should of".

Is it time for another "Uboats vs. Fleet Boats" thread?


I vote for the B-29!

That's Bull.

You don't like the B-29?

Perhaps you prefer the Dornier Do 200 or Do 288?


It seems the Japanese used them as well:
