New Torpedoes

[M. Sarsfield]

I would assume that it's an easy change/addition to a config file. If we can add new ship models, you shoudl be able to crate a new torpedo model.

I found this site talking about homing torpedo development from 1940-1946:

... and post-war "heavy weight" torpedoes:

It looks like you are after the Mk. 31, which is a Mk.18 equipped with passive homing.

you can change easily the type, warhead and speed/range as idid to model the ijn type 93 and 92 (e) but i don't know about homing, will look into it

Here's an interesting tidbit that I found:

Prior to the mid-1960s Soviet submarines had diving depths of 650 to 1000 ft and submerged speeds under 30 knots.

This should help with some of the torpedo parameters. Also, early acoustic torpedoes had safety features that prevented them from doing a 360 on the launching boat and a minimum operating depth so that they would not attack nearby ASW/friendly surface ships or even the launching sub at persicope depth.

Thank you M. Sarsfield, you've brought precios infos!
I'm currently at work with s3d to understand how a torpedo works (in game) and how to make a new homing torpedo...I think the best results would be achieved by "adding" new torpedoes instead of transofrming existing ones.

I'll keep you informed!

If anyone has some clues or ideas....be my guest.

[keltos01]

transforming existing ones reduces dramatically the amount of work necessary, as you have to edit quite a few files referring to the torpedoes you're using including the sub's. I plan to do that to go along with the human drivable japanese sub we're currently working on : a junsen B type. Have you asked the russian team ? I got their november design for a sub, which in turn should help me with the Junsen B.

This is the first time I ask for help with torpedoes, and I haven't asked the russians yet. I know that if I re-work existing torpedoes I will avoid a lot of extra work, but the fact is that I doubt I will be albe of creating a new homing torpdo using the mk 18 or the mk16 as basis. I modded the mk27 to a mk16 type of torpedo, but the result was a failure. The model used by the game was the short mk27 one, and even the proprieties of the torpedo (explosive power, speed, propulsion etc) remained the mk27 ones.

Basically I need to start with a G7e T-V like homing torpedo.
Is it possible o change the torpedo model of the mk 27??

[M. Sarsfield]

More than likely the Mk 27 has sensor nodes on it, like the ASW ships and aircraft. The Mk. 18 probably lacks nodes, since it's a straight shooter (after turning to the proper course set by the TDC). If you sped up the Mk. 27 and improved it's listening range (out to 1,000 yards), it could mimic a Mk. 31 or other early post-war acoustic torpedo.

For a late Cold War acoustic torpedo, modify a Mk. 14, since they eventually returned to combustion engines for torpedo motors - albeit much quieter and faster. Also, the Mk. 14 should have at least one node on it, since it uses magnetic detonation and it has to sense the the target to detonate. Just change the node to passive/active homing.

Post-war torpedoes had other features, too, like noise filters and delayed receivers (for active homing), so that they would ignore false echoes from cavitation, the sea floor, etc. when sending out a ping. They also designed in more sophisticated search patterns where the torpedo would circle and/or fish-tail as it listend for and closed in on a target. The Mk. 27 is pretty unbiased as to what it locks on to and in addition to slow velocity, it has a slow turning speed.

WWII also saw the beginning development of wire-guided torpedoes, but they weren't refined until the 50's and 60's.

Ironically, Mk. 14's stayed in service until something like 1981. Probably for training purposes.

If you read through the two links that I sent you, you'll get all sorts of cool ideas for Cold War fish.
