The US periscope isn't slaved to the TDC so you have to use a different method.

If you know how to use the SH4mission editor, open the torpedo training mission and drag your sub down and to the right 2,000 yards or so and give yourself a little more time to do all this. you can save the game at first contact and try different approach angles, ways to plot the course and get speed, etc.

Also if you're doing the unlock the scope and sending bearing ahead of the bow you will hit a little bit behind where you fire the torpedo at so you have to make a small adjustment as to where you shoot, A shot right at the bow will hit a little aft of the bow.

And herein lies the root of all the trouble I've been having....!

So am I right in saying that under normal circumstances my torpedoes will not go where I am pointing the periscope but rather where the TDC is currently programmed to send them- unless I'm locked onto the target of course?

I spent some time last night playing around with the mission editor as you suggested. I am now able to hit things fairly regularly using a continuous bearing attack which is a good start, I am certainly beginning to understand the greater flexibility of the US TDC in general.
I attempted the unlocking of the scope, and taking a range bearing slightly ahead of the target, turning off the TDC and firing when he crossed the wire, but my torps always seemed to go to the same place (in relation to the target) that I took the final bearing from, ie ahead of the bow. I can understand why this is considering the first line of this post but can't quite work out the fundamental step in this process that I am missing.

And yes, I need a lot more practice as it is indeed not a piece of cake:woot:

Once you have a firing solution and start the PK it doesn't matter where you point the scope. The PK will Keep that firing solution unless you change it or turn off the PK. With the PK off the TDC will have your firing solution in it but will not update it as things move along.


You want to unlock the target, move the scope a few degrees ahead of the bow and than turn off the PK and than send range, gotta be very quick doing this or you will hit too far back on the target. The longer the PK is off before you shoot the less accurate your shots. Even being real quick the torp's will hit a little behind your aim point.
On that Mogomi I shoot right at the bow and will hit about the first gun turret at 1700 yards. The longer the torp's take to get to the target the farther back you'll hit, this is a 2000 yards or less method. Any thing longer that that I'll use vector analysis shot. Deadly accurate at long range.

Seems like you are getting a handle on all this and yes practice is the key.

Don't sink them all, save some for me. :D

Cheers Magic, I'm sure there'll be plenty left for you to sink mate!

So for a fixed bearing (of less than 2000 yards) it should be-

-Unlock target
-Turn off PK
-Send range with scope in new position
-Shoot quickly afterwards

Vector Analysis shot?! Waaaarrrrgh :wah:

Do it all quickly.

Vector Analysis, Just wanted to give you something to think about.:D:D

Magic

Thanks for all your help Magic, very good of you to take the time sir!

Once I've absorbed all this and am able to put it to good use, especially the fixed bearing, then I shall move onto the V.A.S :D
