In a current test mission, I have a Trafalgar attacking a Brazilian CVBG. It fired a couple Harpoons, then dove down and fired Spearfish and Tigerfish torpedoes at a small surface vessel, in two salvos.
Now the odd thing happened, one torpedo hit the surface vessel and sank it - and immediately the Spearfish of the second salvo turned away 50 degree to target another vessel, while the Tigerfish continued it's run on the sunk vessel!

Well well well
I keep trying to tell you the Spearfish is better than an adcap

Heres a little something i've found on the net about the spearfish .....
"Spearfish was originally designed in the
late 1970s to replace the ageing Tigerfish heavy_weight torpedo. The requirement was to provide the Royal Navy with a capability against the large aircraft carriers and the (then) new deep_diving, titanium_hulled, very fast Alpha class submarines. Also, Spearfish was to cope with the various
countermeasures, jammers and repeaters thought to be deployable. In the event, only a few Alphas were built and the political scene has moved on.
Nevertheless, Spearfish is in service and
provides the Navy with the capability it required.Today, the requirement has expanded to include a slow or stopped target capability in very shallow water. This aspect of Spearfish's performance is still under development. However, Spearfish has recently demonstrated performance against slow submarines and stopped ships in shallow water. As such, it is the only heavyweight torpedo in service in the world with this capability."
"Spearfish is a 21inch (0.53_m) diameter heavy_weight torpedo. It weighs approximately two tons(2_000_kg) and can travel at greater than 50_m.p.h. It carries a forward_mounted sonar array digitally_
controlled and capable of both passive and active operation. The torpedo has been designed for primarily autonomous fire_and_forget operation whereby once the submarine Fire Control system has
downloaded all the requisite target and environ_mental data, the weapon will make its own way to the target and commence the prosecution with its sonar. A wire link to the submarine provides two_way communication for as long as the link remains physically intact. This provides weapon position and contact details to the submarine and, in return, enables the Fire Control solution to be updated or the weapon manually controlled."
Hope this explains a little
Heres the link to the site where i got this info from

Today the AI wire-guided a ADCAP on me. A 688(i) fired an ADCAP on me, I tried to run out of its search zone, put failed. Then I did my standart evasion maneuver. I let the weapon come in and when it was at about 1000 yards I hit flank, at a course +90° of torpedos bearing. Then I let the weapon come in to about 300 yards, fired a CM and made a 180° turn away from the weapon ( about 60-70% sucess rate ). The weapon passed me about 100 yards. I was happy and went down to 5kn. Then some 20 secs. later I heared some pings and boom, I was hit. The replay showed that the weapon did a big 180° turn directly back on me. Tha AI must have wire-guided the torp back, because I never saw a weapon in SC reaquiring after a miss. Very cool.

TK, how did you change the weaps for extra playables? I thought you can only fire the weaps from the default subs?

Fancy things, the British torpedos! 
Stewy, the Trfalgar used it's usual payload as per default, didn't change anything on it.
I just put it in to test paints, that's all.

Hi TK
Personally ... I think you were 'Zonked'. 
Individual 'capabilities' of Torps are not modelled in the Sim ..... yet. However, by default .... the Tigerfish will 'perform' i.e. Acquire and Lock .. better than the Spearfish, due to it's lower speed.
If anything, the Spearfish lost sight of the Target ... especially if it was a Passive .... which the AI do fire, irrespective that they have Passive Sensors attached ... or not.
What 'is' it you drink anyway???
To MBot: The 'Active' Adcap has re-attack capability. If it misses you the 1st time .... it will turn around and try again .... as you had said it was pinging, therefore it must have been an Active. There is very little chance that an Adcap Passive will re-attack due to some problems with the logic ... by default in the sim. I have fixed this in my mods.
I haven't seen anything happen in the sim, that would suggest that the AI 'uses' wire-guidance. In fact, all evidence points to the contrary.
Cheers
Tom

Tom ol'bean of course I was zonked, after all that way I am most creative
But I swear to you, one torpedo immediately turned away as the small vessel was sunk while the other one stayed on course, was about 5 nm out of the target, now what was it, think the Bosisio or what.
I could send you the test mission in question, although it won't work with your DB anyway since there's a couple separated entities in it... as said, it's just a 'Show Truth' mission for testing this and that eye-candy...
Btw when do you release your torpedo mod?

Btw it's beer, and only beer, no high percentage stuff or what - would put me in a coma anyway...

Hi TK
Oh ... I do believe you .... I've seen it happen many times .... although not specifically with the Spearfish.
It's all dependent on the level of confidence that the Torp has on the Target. As the Target slows, or stops ... it's noise level would also drop accordingly. An Active is much more inclined to go after a 'dead' Ship, than a Passive would. After all, an Active will always get a 'return' off a ship whether it was dead or not. There is no logic ... that I have seen anyway ... that would tell the Torp that it's target is 'no longer valid'. In your case, the Tigerfish, due to it's lower speed, would have had a higher level of confidence on the 'dead' ship. The Spearfish's level of confidence would have already been lower ... due to it's higher speed .... and thus, when presented with a 'better' contact, will attack that one instead. In reality, I'm sure that some Torps would have this capability ... however, it happens in the game .... solely as a result of the way
the Sensors work. So, it does 'look' or 'seem' great when the Torp does things like this .... as it suggest that there is some higher level of AI at work ... but, I'm afraid to say ... that it just ain't so.
The Torp actually stores contact info, and generally will attack the one that it has the highest 'level of confidence' on. If it's 1st Target's 'level of confidence' drops sufficiently ... it will drop that target ... and go for the next one.
I've also seen Torps 'veer away' from a Target, if the Torp is still far enough away, and is 'blinded' by a previous detonation, from an earlier Torp.
What I've done with the Adcap, due to it's multiple sensors ... is give it a slightly more advanced 'Acquisition and Homing Phase'. It will prioritise targets depending on where they are .... with Targets directly in front of it ... obviously having the highest priority ... and not necessarily the one it has the highest 'level of confidence' on.
In due course, I'll have given each Torpedo independent capabilites (I've only done the user ones thus far) .... and each with their own doctrine. (once again, I've only done the user Torps thus far).
Re: Releasing the Torp stuff etc. .... it's close. Spent a lot of time putting new sensors on the Subs ... all the Subs have their own Sensors now. Really been having a problem with the Types and Ranges (so much conflicting info). I'm primarily testing and tweaking now. Also, haven't been able to do much over the last 3 days ... had other issues to sort out.
Soon ..... I hope.
Cheers
Tom

Thomasew,
I put your mod in and it didn't completely work. Did I have to change the torp themselves with ludgers edit?
The ADCAP still has 360o sonar.
What am I doing wrong??
NB. The Spearfish is highly advanced, and it speed is supposed to be 70kts. I read that some where.

Hi Guts
You must be using my old mod ... haven't released the new one yet.
The old mod uses the default database, so ... the Adcap Sensors are the same as the other Torps in the game.
Cheers
Tom
