AI working acoustic torpedo ("fido")? Take a look!

[Rubini]

Hy guys,

Last days with few sleep ... the Ai torpedos matter is really very interesting!:

I finished the Air Torpedos, tested it on campaigns, save&reload campaign games, all working ok and with random Air torpedo bombers covering all the war time following the allied air coverage. It´s ok and ready for release.

But then I found something new. I as able (with some tricks) to have also a "real" working Ai acoustic torpedo (without use of Virtual torpedos)...take a look yourself on the videos below.

In truth they continue with that old limitation to only be spawed going to north...but with some tricks they are working, finding loud propellers in any direction. They are very good in behaviour for my taste. Let me know what you think.

surfaced
submerged



Ahoy!
Rubini.

PS: correct me if I´m wrong: Fido and others acoustic torpedos were eletric ones and didn´t had visible trail over water? Is this correct?

Great work Rubini! It looks marvelous (and horrible at the same time - I don't think I'll be sleeping too good myself thinking about 1943 and those damn Fidos hunting my poor boat)

Looks like your onto a winner Rubini

OMG, this is fantastic Rubini. First Air torpedoes and now FIDO, the seas have now become a terrifying place to be.

As far as I know, they were indeed electric, Falkes, Zaunkönigs and Fidos. There should be no clearly visible trail like the one a G7a torpedo in the game leaves.

(However there is a mod in downloads section that adds some trail to electric torpedoes. I don't know how realistic that is but I would guess that any torpedo would leave some trail behind it that would be visible at least in very calm waters.)

Thanks by the input. Let´s wait more opinions about, then I will finish the mod!

Another great addition.

I can't wait to try it

Rubini, very nice indeed, but I was just wondering if there is any defensive tactic that would avoid the loss of the U-Boot. i.e deeper submerge, turning off all engines and/or more evasive maneuvers? Thx

Yes all the above works, mainly going very slow or going deep. Also high speed manouvers can help but if you have more than one fish on water will be difficulty to avoid all them.

Great work, Rubini...
Sorry my ignorance but i all aways think the acustic torpedos was exclusive used only by the Krigstmarine in the W.W.II.

How deep will the torpedoes track you?

My normal procedure with aircraft is to crash dive. I suppose if the aircraft drops close to my position, the fido may hit me pretty close to periscope depth, but I wonder if they will pursue you much below 25 meters or so.

Just wondering.

Looks like a very welcome addition. Thanks for your work.

The Allies developed the Fido air dropped torpedo later in '43. Some of the accounts I read in Michael Gannon's "Black May" were pretty chilling. He gives a pretty detailed account on their development and use.

Fleet boats in the Pacific used acoustic torpedoes later in the war as well.

I understood that Stiebler has modded Fido so that the torpedo will follow you regardless of depth if it can hear you. That would mean going slow is the only way to lose it.

Allies had the FIDO (an acoustic torpedo) after 1943 and it was used against uboats.

In my tests seems that they will catch you until 12-15m below water. I don´t know if this is historically correct but is what we have in game. The ai torpedos are a compromisse because Sh3 lacks totally the code to control them. Anyhow seems that even in Sh4/Sh5 their stock routines isn´t that good. Remembers me about lifeboats, where the sh3 mod works frequentelly better than the original Sh4 code...

[Rubini]

Ok! Tests finished, success, so, we will also have acoustic torpedos on the Air Torpedo mod.

The mod idea:
At the beggining of war, until 1943, we will have only aerial direct torpedos. After that, the Avengers will carry aerial or fidos. This will achieve by holding both virtual torpedos and the "real" acoustic ones on the mod.

This means that, when attacked early war, if not get hit by torpedo quickly, (max. one or two minutes after release) no more torpedos left on that attack (simulating only direct aerial "virtual" ones). But late war you can be hit even some minutes after the attack by "real' acoustic torpedos, even if submerged until 15m. No wakes trails on acoustic torpedos...if you want to see then take a look at your back in external or object view.

By Sh3 limitations, you will not see any torpedo just after it enters water. The acoustic ones (FIDO), will be armed several seconds after it enters water and then they becames visible using external camera.
