Preferred Sonobuoy?

OneShot:

'Dr.Sid ... take a look at FAS or GlobalSecurity.org or some other pages and research the differences of the
buoys used in DW. You will notice that they have quite differing characteristics and uses. To stay with the VLAD
... before 1.03 there was no real modelling of the layer as well as uniform buoy depths which were not really
consistent with what should be according to unclassified Real Life sources. Since VLADs had a slight advantage
(not more then 1 nm ususally, mostly less) and otherwise same characteristics as DIFAR, the choice was simple.

Now with 1.03 we have a clearly modelled layer which is usually deeper then the old Deep buoys (400ft). After a
lot of lobbying SCS finally agreed to bring some more realism into DW and fit the buoys to the new conditions
and their real life counterparts (certainly not perfect, but close enough for gameplay purposes).

So what are the buoys for ? DIFAR are good for littoral waters and can go as deep as 400ft, VLADs are designed
and used in open waters of usually 800ft and more (VLAD Shallow is now 600ft). DICASS retain both a very shallow
t) and get a slightly deeper depth then before to get below some of the layers. And not to forget the cable
of the Hydrophone was extended to 2500ft (or was it 2000ft) and speed of deployment increased.

With these changes the Airborne plattforms are now capable to reach below the layers.
Bottom line, every buoy now has its strengths and weaknesses and your loadout has to be careful selected before
starting the mission. Yep that might suck in some cases for the FFG drivers with AI Helo, because they may not
be able to use all of the buoys, but th'en hopefully sooner or later the ASTAC station will get a revamp...'

'Going crazy after the narrowband identifications'

TLAM Strike:

'Ok each platform’s signature has five lines (called Tonals). Each of these tonals is generated by something on
the boat (a electrical generator, a turbine etc). The objective of a narrowband classification is to match all
five lines (if possible all maybe not be visible to a sensor) to a signature in the database. Now each set of
tonals is different in some aspects platform to platform while others are the same, generally the 1st few lines
are shared by many platforms (example the Akulas and Kilos both share a 50 Hz and 125 Hz tonals) while the 2nd
two tonals tend to be unique to a few platforms and the last one is used by one or two platforms. Another thing
to remember is the frequency range of each sensor, a Spherical Array can detect tonals of around 800 Hz to 2000
Hz while the Towed Array can detect 0 to 1200 Hz, and Conformal Array is around 100 Hz to 600 Hz.''

'TLAM strike gave the essentials, though it may be a bit hard to read.

I'll also give you some rules of thumb to go by.

All non-US platforms in the game has the first line at 50, while US ships and subs have the first line at 60.

This line can only be seen by a towed array.

The towed and hull arrays can detect the 125 lines which all subs and a few ships (most notoriously, the
"fishing boat") has in common.

Every nuclear powered sub (at least the playable ones) has a 320 line. The kilo has a 340 line. (Though if you
see that, he's running diesels, cavitating, or just too damn close)

From around 1000 and up, the lines show up only on the spherical array.

Each platform has a unique signature. (In the game, platform refers to class of ships instead of each and every
ship, as IRL) However, there are two cases where you'll get the wrong signature on screen. The first and most
common, is the partial signature. If you only have a 50 and a 125 line, you can scroll through the possibilities
- which include every sub not US-made, as well as plenty of both civilian and military ships. If you get a 320
on top of that, the selection is narrowed a lot. As the signal gets better (less range, target becoming noisier,
crossing layer, etc etc), you'll get even more lines.
The other case is when you have most every line, but two signatures are close to each other. There is a bit of
uncertainty allowed in displaying the signatures, and you have to determine which one matches the best. (Beware
of the doppler effect) '

From CADC Posted 19th March:
'How to use the Speed formula.'

Oneshot:

''This is about the formula for calculating the speed of a contact from the P-3C OWTOP Manual, page 24.

For this forumla to work you need two successive contact positions, for example two MAD returns. Now place the cursor on the first MAD contact and hit "R" - without clickin draw a line to the next contact and read out the distance between those two. Thats the distance ... for the time you need to put down markers with the time when this position was marked on the NAV map (check the manual how to do that). Means both Markers you used should have a time attached. The difference in minutes between those two markers is your time in the formula.

Example :
First contact at 1235, second contact at 1237 = 2 minutes between them. Distance measured between those two is 1000yds. Divide the Distance by the time means 1000yds by 2 minutes. Multiply the result with 60 (for 60 minutes = 1 hour). The last step is to divide that result by 2025 (because we are using yards for distance and 2025 yds are 1nm). The result would be 15(kts).

Just the numbers :
1000 / 2 = 500
500 * 60 = 30000
30000 / 2025 = 15

You can use whatever time lies between your two positions, just.the example uses 2 minutes.''

Passive Torps.

Dr.Sid:

''Have you ever been targeted by passive homing torpedo from AI ship ? Does it have any sense to drop both active and passive CMs ? I mean .. passive CM makes a lot of noise, giving your position just to everybody (who does not know yet). It also masks torpedoes so it is harder for you to track them. And what more, you can load some active CMs instead of passive ones.''

Molon Labe:
Posted: Mon Feb 20,

''I don't think AI fires passive torps, but humans sure do! If you're playing with LW/Ami though, passive torps have a very hard time acquiring subs are are practically useless against them.

On the other hand, once Amizaur's torp control mod is finished, passive decoys may become a lot more important, since the player will be able to switch the torp from active to passive homing at will!

Edit: Here's a tip. Mark the incoming in BB and check the speed in DEMON. If it's 50-55 knots, it's active. If it's turned down to 45 or lower, it's probably passive, so get the right decoy ready! (TEST-71 exempted) ''

I got hit by a passive torpedo fired from a TYPHOON SSBN the other day. It never pinged once. I suspect it had to do with the sub being set to "avoid" hence it tried to remain more stealthy.'

Re: Horizon Calculator - Radar and Visual.

Subguru:

''Quick rule-of-thumb I was taught in the Navy:

Radar horizon (in miles) = 1.4 * sqrt (height in feet)

Thus, a height of 100 feet yields a radar horizon of 14 miles

(compare with 14.146 using the Horizon Calculator) ''

RECYCLE 8.

Fish has posted on Subsim.Com :-

''Better then EndItAll.

- But more complicated''.

RECYCLE 9.

The UUV.

Fish:

''Triangulation with a UUV is common use in multiplayer. Further, you can use it to look over a reef or around a seamount.
It becomes very usefull when you have to go at speed to evade, or sprint and drift. The UUV then can follow, or warn you for, incoming torps. And it's very acurate when you use it in active mode when it gets hot. Launched below 520 feet, and with depth setting below 520 the UUV will not generate TIW. You should try, I have always two loaded and two in stock, at least.''

Molon Labe :

''UUV's are a great idea in a lot of situations.

The main downside of the UUV is that it will often reveal your location. Below 520 feet, it doesn't generate a TIW, but it still generates a NB signal. The UUV can only go 2.5 miles, so when you find one you know the launching sub is close. For this reason, the worst way to use a UUV is when you're searching the open ocean and you just don't have any contacts yet.

The other downside of the UUV actually relates to aTMA. If you are using aTMA, and there are a lot of contacts out there, firing a UUV is the last thing you should do. Too many contacts will be reported to TMA, and your solutions will not be updated as quickly as you need them to be.

That crud out of the way, I have to say that I love UUVs. The best thing about them is they keep listening even when you're running at flank. A UUV contact + spherical/cylindrical contact is a great way to find out exactly where an ASROC or Mk50 dropped so you can react quickly. They're your best friend when it comes to maintaining situational awareness when the **** has really hit the fan.

Other benefits: Triangulation, peeking over/around terrain features, sending the other way around a large island so you don't end up chasing your opponent in circles all day...''

TLAM Strike:

''But the UUV can be the worst thing in your inventory if you don't know when to leave them on the pier. On the Kilo 95% of the time I don't carry them since...
A) They take up very scarce torpedo space.
B) They take up your even scarcer wire guide capable tubes.
C) They are quite useless in ASuW, which is what the Kilo is meant for.''

JoGary:

''Yeh for Kilo they take up a wire guided tube and u only have 2 but for all other subs they a must have. I dont know anyone who is good in Sub v Sub dives that doesnt use a uuv. Also i have to say that if the UUV is launched below the 580ft then it does not cavitate and so hears better. Alos if it not cavitating then the NB signiture is way smaller than the signiture a SW at 0 kts gives out so i dont think there is a problem with giving your position away unless you set the active sonar to go on.
But as said if there is alot of contact which there usually are in Sub v Sub games. Torps, neutrals, subs and bios. Then it takes the TMA ages to go through them all and update the position of the one you want updated. But having said this it is a must have on all subs but Kilo.

One trick i use when torps are near me is to launch another UUV and have 2 in the water. This way you can get exact positions of the torps as they move and dont need to wait for TMA updates. All u have to do is keep dropping the baring lines when they stop moving. By doing this u get new baring lines from both UUVs and where they cross is a torp. Also for firsy few min they will actually move and follow the torp so you get real time data from the baring lines. After a while they stop moving or TMA gets done on them and then u have to drop them again. But by doing this you can track torps all the way to your CMs .''

'Kilo weapon loadout.'

Kirk:
''Anyone know what weapons go in what tubes in the Kilo Sub. I was playing around that that sub, which is pretty cool and noticed on the tubes that some of a "P" which I remember from the other subs that means program for a waypoint. And others have a "P" and "W". Anyone help me with this? Thanks.''

TLAM Strike:
Posted: Mon Mar 06

''Tubes 1-4 are standard tubes that are loaded from the "Main Rack". These can fire anything but wireguided weapons (TEST-71s, UUVs etc)
Tubes 5 and 6 are loaded from their respective racks (#5 Rack etc) and can launch any weapon and has wire guide capablity.

The P is for the tube's Presets screen (RTE, Depth, Speed etc) the W (on 5&6) is for the Wireguide screen for that tube.

NOTE: TEST-71s should only be loaded in the Tube 5&6 racks NOT THE MAIN RACK! They cannot be loaded from the main rack to tubes 5 and 6 (SCS Really should remove them from that part of the loadout screen or make them capable of fire and forget use ) Also the PLAN TEST-71s once enabled and locked on to a target cannot be pre-enabled and redirected to another target, they can only be shutdown or pre-enabled (which just prevents the weapon from exploding).''

''TLAM Strike yes, putting "---" as they did for the UUV in the TEST-71 main rack cell.

TLAM Strike Well, this occur only for the TEST-71 ME-NK used by the chinese improved KILO.
TEST-71 M (russians) & TEST-71 ME (chinese standard KILO) could be guided as wish once they have acquired a target.

it's strange a more sophisticated weapon could be less efficient than the older version : TEST-71 ME-NK of the improved KILO inferior to the TEST-71 ME of the older KILO.

'Setting Gamma is a must do.'

TimmyG_00:

''Back in the old Sub Command days, Killerbuds and I were testing SCX detection ranges.
The way we discovered the gamma issue was that we were each driving a Seawolf, and although
I could see his NB lines, he could not see mine!

He took a screenshot of his NB screen... and I could see my NB line in his screenshot! So I surmised that
there must be a monitor or graphics setting that was affecting his ability to see my faint lines.
This was essential for inclusion in the TACMAN.

With Sub Command, it seemed that the Gamma setting at the graphics card level did affect the graphics
of SC in full-screen mode. I think that might be a function of which graphics card you have. I haven't toyed
around much with itRe: Setting Gamma is a must do. Get Tacman from Bills - included wth the DL is a bmp file
specificaly to enable you set up your monitor to show the very faint NB tonals.''
