It's a bit late but better late than never I guess.

Here's a compilation of information not included in the SCXII readmes. Some of this was available in SCX 1.x readmes, some was ripped off somewhere else.

First, a tidbit about wakehomers:
Wakehomer torpedo will ONLY work at 10 meter depth!


Second, guide on how to use advanced torpedo programs (Tom's torpedo mod included in SCX)

************************************************************
TTT Mark 25 & 3/4s - A Torpedo Mod for Sub Command - by Thomasew

This Mod comprises 2 files...the 'Torpedo.txt' and the 'Torphoming.txt'. Installation is a simple matter of copying/unzipping these 2 files into your '\Sub Command\Doctrines' folder. Please either rename, or make a copy of, your existing ones.

That's it....give it a go.

There are a couple of things that I would like to suggest, and although they are not necessary, I highly recommend you implement them. It will make your experience with Sub Command that much more realistic.

The use of the excellent Editor by Ludger is required for this, so if you don't yet have it, I suggest you obtain it as soon as possible.

Firstly, backup your entire database folder....all the files....just in case.

Load SCEDit.

1. Load the 'Sensor Dialog' from the toolbar...it's the 4rd button from the left (has a Radar icon on it)

2. To make a 'record' active, all that is required is to Double-Click on it.

3. Double-Click on the record for '0007: Wep Sonar (Wep Sonar)'. This is the Sensor for the 'Active' Torpedoes.

4. In Field 1: for 'Detection Curve Ranges', you should see a value of 4000, indicating that this sensor has a range of 4000 yards. It's a little low, so change that number to 5000.

5. Click on 'Apply' to write these changes to Memory.(NB. not written to disk)

6. Next...scroll down the list until you find 'record' 0070: LF Pas Son (Wep Pas Son), and double-click on it to make it the active record. This is the sensor used for the 'Passive
Torpedoes'.

7. In Field 1: for 'Detection Curve Ranges', you should see a value of 45000, indicating that this sensor has a range of 45000 yards. This is seriously way out....no way can a little 'itty bitty' sensor in a Torpedo have almost the same detection capabilities as the 'Towed Array' on a Submarine. Some people have suggested that the figure is this high to compensate for the 'Passive' sensor 'washing out' (losing detection). Anyway, please change this number to 3000 (Yes, three thousand). This indicates that the 'Passive' Torpedoes will, or should, acquire a target at a range of 3000 Yards or 1.5 Nm...which is much more realistic. Believe me, this figure works just fine. I've run hundreds of tests.

8. Once you have entered that number, then click on 'Apply' to write the changes to memory.

9. Close/Exit the 'Sensor Dialog' window

10.Click on the 'Save' button (of the toolbar)...3rd from the left....to Save your changes to disk.

There is another 'optional' component...and that is the addition of a MAD sensor. And no, it's not a crazy sensor.....although it results in some crazy effects when the Torpedo detonates. What this MAD (Magnetic Anomoly Detection) will do, is to compensate for near misses. If the Torpedo passes close to the Target, say within 50 yards or so, there is a good chance that the MAD sensor will trigger the Torpedo, which results in proximity detonations. Very cool effect...if you're into that sorta thing. The end result is a better chance of survivabilty should a Torpedo detonate close to you.

Anyway, it's not required right now...and because I've had some queries regarding 'Contact/Moored' mines...and getting them to Detonate, I'll post a short 'How To' on how to set up and attach MAD sensors on the Subsim Forum, in the 'Modders Only' Topic.

Just in case you haven't read my posting on the Forum regarding this Torpedo Mod, I'll summarise briefly here.

Essentially, for all intents and purposes, the Torpedoes, in 'Basic Mode' will work exactly the same as before, with one or two exceptions.

1. The Torpedo, irrespective of it's Speed at the time it 'acquires' a Target, will attempt to accelerate to it's maximum speed in it's 'homing' phase.
2. If the Torpedo subsequently loses track, or contact, on the Target, it will attempt to re-acquire by decelerating back down to it's 'Preset' speed. Going slower will give the Sensors a better chance of re-acquiring. It may circle, it may snake, and is dependent on numerous variables....so, please don't expect it to automatically re-acquire. The same principles will apply to those Torpedoes that were 'spoofed' by decoys. Once they realise they have made a 'fool of', they will/should decelerate, and start searching again.

And that's it for the Basic Mode of Operation....


Advanced Mode: What this does, is to give you more control over your Torpedo, once it has been 'Launched', and comes in the form of 3 Usable, and 2 'No-Op' pre-programmed modes. These 'programs' are initiated and selected via the 'Torpedo Control Panel' where you would have already assigned your 'Preset' Speed, Depths etc.

Selecting a 'Program Mode' is a simple process of pushing the 'Enable' button, followed shortly thereafter by pushing the 'Pre-Enable' button. Unfortunately, Program modes can only be selected sequentially. i.e. You would have to go through Program 1 and 2....to get to 3. This may require a little practice to get the timing right. The only real issue you have to concern yourself with...is when you are trying to activate a program for an 'Active' Torpedo. If, during your selection of a program, you leave the 'Enabled' state active for too long, the 'Active' sonar may emit a Ping or Two, before you press the 'Pre-Enabled' button, to switch off the Sensor.

The Pre-programmed modes are as follows, and as already mentioned, selectable by first pushing the 'Enable' button, followed by the 'Pre-Enable' button. The Torpedo, when first launched, will continue at the depth, and speed, it was launched at.

Program 1: The Torpedo, at it's current speed, will go to it's 'Preset Depth'

Program 2. No-Op...reserved for future use. The Torpedo will do nothing.

Program 3. The Torpedo will either Accelerate or Decelerate to approximately 2/3rds of it's maximum speed. It will remain at the current depth.
Program 4. No-Op...reserved for future use. The Torpedo will do nothing.

Program 5. The Torpedo will return to it's original launch state. That is 'Depth at Launch' and 'Speed at Launch'. e.g. If you launched the Torpedo at 500 feet, with a Preset speed of 30 Knots...then it will return to these parameters.

Once Program 5 has been initiated and completed, the internal software will be reset, and any subsequent 'Enable/Pre-Enable' sequence will start from Program 1 again.

Also, if at any time, the Torpedo acquires a Target and engages it's homing phase, the internal software will be reset back to Program 1.

So, you can see from these few simple Program Modes, that you have far better control over the guiding of your Torpedo, and thus, are better able to position your Torpedo to your Tactical Advantage.

For instance...you could launch your Torpedo at a depth of 500 Ft, with a 'Preset Depth' below the layer. Once the Torpedo has been launched, you can initiate Program 1, which will effectively put the Torpedo below the layer. It could then traverse under the 'layer' until such time as you required it to 'Pop-Up' back to it's Launch Depth (500 ft in this case) by initiating Program 5. You could then enable the Torpedo at this depth, which would activate it's Passive or Active Sonar, and it would continue searching until it either acquired a target, or you 'Pre-Enabled' it.

Conversely, you could do the opposite, and launch the Torpedo below the layer, where it would stay until you initiated Program 1, which would take the Torpedo up to it's 'Preset Depth'. Obviously, initiating Program 5, would bring it back down again.

Having dual speeds also gives you some additional tactical advantages. You could launch a Torpedo at long range ,basically as slow as you wanted, in an effort to avoid it being detected. Once the enemy eventually became aware of the Torpedo, and was attempting to outrun it...you could initiate Program 3, which would allow the Torpedo to accelerate to 2/3rds of it's maximum speed. In the case of a Mk 48 ADCAP, this would be 42 knots, and in the case of a Type 65, this would be 38 knots. No Ship, nor Submarine, could outrun it.

Conversely, in a 'quick kill' or 'snapshot' situation, you could launch a Torpedo at full speed towards the enemy, and once it was close to it's 'Enable' point, you could activate Program 3, which would allow the Torpedo to decelerate to a slower speed, at which it's sensors would operate more efficiently.

Etc...Etc....

I am sure I said 'summarise' somewhere back there.

Anyway, that's enough technical blurb. I am planning to upgrade this Mod to allow for further Programs that would allow you to set the Torpedo to go to the 'Floor' depth and the 'Ceiling' depth. Most of it is already done....but it would amount to having about 8 or 9 different programs for Torpedo Control. Therein lies the problem...no feedback...except for visual....as to what Program Mode the Torpedo is currently in. This is something you will have to do yourself. That's one of the reasons why I didn't want to implement too many Programs right now. Also, I would like some feedback and suggestions. Both are most welcome.

Pease post any questions, or feedback etc on the 'Subsim' forum. I will be posting some notes on setting up the MAD sensors etc., shortly.

'til then

Enjoy the Mod

Cheers
Tom
