SSGN Behaviors

[stormrider_sp]

I´m always trying to create missions, but they never work as I want or should....

The first thing I do before I create the mission, is a test mission, to actual test the behavior of the AI. I like the idea of editing doctrines, but can´t.

I will post here some results I got by testing.

-Oscar II attacking.
If the Oscar II detected a surface:
If it was stated at the mission editor that it should "attack" (not track, nor avoid) than it will launch few weapons, quickly.
If it was a script "engage" with "weapon" than he will attack with more fury.

If the target is a "remote", I mean, a promoted link, then he won´t launch a salvo, but 1 missile after another, after waiting for a long time. If the target was an Arleigh Burke (L&A Mod 2.0) then it will probably never hit a single missile. Where is the salvo??

If you order 2 SSGNs to attack a single target, then only 1 will attack.

The same goes to my "edited" Ohio SSGN, and its 154 TASM


For submarines.

I would like to know more about tactics.
I know that if the sub is driving a transit traffic than it will be completly blind and unarmed, unaware ship.
Oposed to Transit Search.
But how about, Random, Ladder, Expanding box, Perimeter? Are they searching or just playing ducks in the water?

Sometimes they will launch snapshots when attacked.


I came with this questions because I was building a mission where an american CVN, well defended, operating in the area had to be attacked by russian SSGNs.

There were a few american SSNs defending the CVN perimeter waypoint.
The red side was compoused by 2 groups of 3 subs (2 SSGNs and 1 Akula Imp. and 1 Victor III) and an Akula II.

The concept of the mission was to drive the Akula II into the frontline, detect, classify and promote the link to the SSGNs, acting as a intel. The problem is that the SSGNs will take too long to launch not enough weapons against its targets and the Akula II is then detected and attacked. Oh, a suggestion to Luftwolf&Amizaur: I think the American surface ships´ sonars are way too powerfull... They detect an Akula II farther than a 688 does.
Well the mission didnt worked.

American surface ships, with TA's, share the SQR-19, which is the same sensor the FFG has/had. So American ships in this mod are no more sensitive in passive sonar than the FFG in stock DW. Is it possible they had you on active sonar?

Also, I'm not sure but I think the SQR-19 is actually more sensitive than the TB-23 in the real world.

[PeriscopeDepth]

All depends on the mission. If they've got somewhere to go in a hurry (which surface ships do quite often). I think anything over 19 knots and the TA is going to be degraded severely. The total washout speed is 25 knots IIRC.

Edit: And also depends on target speed. And it very well could have been using active sonar.

ive been on the run a few times while on my latest mission a jap kongo DDG chased me before i was able to detect him i was only at 10 knots

i did manage to get away but only just

[LuftWolf]

If you didn't have your TA out (as usual) the Kongo should have had you at 10kts, considering the Kongo has a variation of the SQR-19 TA (in the mod and in RL).

[Kapitan]

the kongo picked me up 10 miles away ruffly because she went full speed at me or close to it

[stormrider_sp]

It is hard to believe that a surface sensor can be more effective than a sub one.

[LuftWolf]

The TA's of surface ships drag far under the water so it minimizes surface noise.

Also, why would the TA station of the FFG be so complex if it gave no advantage over the simplier TA station from the subs?

The relative sensitivities of the SQR-19 and the TB-16/23/29 have not been changed at all in this mod (the TB-23 was added in this mod). However, passive sonars have been assigned to appropriate surface platforms, where 90% of warships had no passive sonar at all before.

[Molon Labe]

Maybe when I'm done studying tonight I'll give an ASUW mission a try and see what happens when a 688I tries to pentrate the whole bloody Northern Fleet on its own. I'll report any significant detections by the skimmers.

In two weeks, the rest of you can try it too! Bill's put a pretty good campaign together.

Hmm I think these days there is no difference in sonar capabilities between a hi-tech sub and a hi-tech surface warvessel but the advantige stays with the sub because he only have to search the surface But I could be wrong

[Ghost Dog]

makes sense to me. a surface ship can not only hold more men and sensor stations to crunch the data, but also sqeeze more computers in as well. The skimmer just cant hide himself from the subs like a sub can.

i remember it used to be rumored that specialized ASW vessels like the Udaloy have special 'creep' motors for times when they want to quiet down. anybody confirm that?

[Kapitan]

i can udaloy does have creep motors as does the type 23 i belive and the udaloy is an offical ASW unit just like the counter part sovremenny is ASuW

[LuftWolf]

The Oliver Hazard Perry FFG has a "Prairie Masker" noise reduction system that, it has been reported, is very effective in masking noises at low speeds.

I'm not sure, but I'd imagine that it is an active sound dampening system, similiar to what is used in the latest Russian submarines, meaning that it is only effective at fairly low speeds because it generates vibrations that cancel out the normal vibrations generated by the machinery of the ship.

[Rob86TA]

"Prairie Masker" is a ring of small bubbles generated around the ship. Presurised air is injected into the water to create a halo that 'lessens' the amount of noise passing through.

These small bubbles reflect sound back in towards the ship, and lessen the amount of noise that escapes past the ring.

I'm only guessing, but I think it would be very dependent on sea conditions, as strong currents/rough conditions/high speeds would tear the 'mask' away from the ship.

[Ghost Dog]

im assuming this isnt modeled in DW? I know that the masker is something you 'turn on' during ASW operations, you wouldnt have enough compressed air to leave it on all the time.
