Anyone operated with wolfpacks? Seen friendly subs attacking?

[Hitman]

With all this mess about the DRM, we had been distracted of what was the most supported petition by the community

What about wolfpacks? Anyone here been able to operate yet with them? Cooperating with friendly subs, or at least have you seen them attack the same convoy?

Come on, I'm interested in knowing what happened to this

[shawnyp420]

Nope. I've even been experimenting with the "Send Contact Report" hoping subs would show up.

[ReFaN]

Not really, but i nearly crapped my pants having 2 torpedoes swish by my own ship, couldnt find the aggressor tho.

this was near Norway during the invasion days.

[SteamWake]

Only passed a friendly sub in the Kiel canal damn near smacked into em they had to throw it into astern flank to avoid me.

[TripleDaddy]

Saw one operating off the coast of England. Thought he was going to steal my kill, but he motored on...

The same goes for British subs. Curious to see confirmations on whether they can dive and attack with torpedoes.

They have been reported to dive when attacked but I haven't seen anything about wolfpacks or AI subs torpedoing people..

We're trying to test this using custom missions but the mission editor is not being cooperative, if you can help, please check this thread.

Have not seen such reports. Can you point out?

[JU_88]

Tested the British U class abit in the mission editor.
I can confirm they can dive and surface -but they seem to a have a few problems with this in shallow depth. (they bottom out on occasion)
I have yet to see one make an attack with guns or torpedos.

Im my test mission i put a submerged U-class up against a german merchent (unarmed)
But the mission screwed up, 3 merchents and and 3 U-class were spawned (stacked on top of each other)
Some took and damage and sunk themselves as a result)

not sure what Im doing wrong.....
On a side note: the 3D model of the U-class is beautifully crafted.

[Nisgeis]

I shelled a U Class near Scapa Flow and the cheeky git dived and then fired two torpedoes at me.

[Kravixon]

I came across a Brit sub of the U class in the mid-north Nord See. I came close on the surface to about 1 km and opened with the deck gun (no torpedos left and heavily damaged on the return trip). He dived after 3-4 impacts so I just motored on full speed away for fear of retaliation.

[piri_reis]

I mean look at the AI Sub Script !
Lots of tactics implemented already.
Run or attack based on time of day and enemy strength, torpedo/guns attack percentage, Get into firing position (there's your wolfpack!), etc.

Perhaps this script can be modified to keep shadowing a convoy and contact BDU/other boats with radio, with all this scripting I would bet it's possible!

Awesome...
Now i Just to finnish this mother off and get her in as an AI/player unit.

(The T-Class = British equivilent of the Type IX & Gato ... gotta love those 11 torpedo tubes )

Hello to all subsimmers.
Good news to us - wolfpacks ARE in game. Don`t know yet how exactly they work, but they exist. You can find them in campaign files.
For example here`s a map of wolfpack operation in "Happy days" campaign.

There are also many single Uboats patrolling.
