Introduction to Airborne Operations in Dangerous Waters
This manual deals with the Sensors, Weapons and Tactics employed by the platforms P-3C
“Orion” and the MH-60R “Seahawk” in the game Dangerous Waters™. In here you will find
the “How-To’s” for using both platforms in a given tactical situation, and other stuff not
already covered in the manual, but needed for operating said platforms. It does not substitute
the game manual! If you have questions and/or problems regarding the buttonologyTM
(means what the particular buttons in a given station do) of the stations discussed within this
manual, you have to revert to the game manual shipped with Dangerous Waters™. If you
didn’t buy the deluxe version with the printed manual, you will find the manual as a PDF file
in the /manual folder in your Dangerous Waters™ installation directory.

The P-3C is used as a Maritime Patrol Aircraft (and in other roles) by various Navies in the
world. The user with the largest fleet and the only country you can fly the P-3C in Dangerous
Waters™ for (at the time of the writing of this document), are the United States of America.
The other playable airborne platform at is the MH-60R. The MH-60R is normally stationed
aboard a ship like a frigate or a destroyer and is used in various roles, one of them ASW.
This document is based on unclassified information and game experience. As our experience
evolves, so do our tactics, hence check back regularly for possible updates.

Since the first version of this manual, I have expanded the scope to include the most popular
mod and its changes to the P-3C/MH-60R in Dangerous Waters™ – the Luftwolf & Amizaur
Realism Modification (short : LwAmi and currently available as v3.10). Stuff only relevant to
the mod is marked [LwAmi] in this manual and can only be used if this mod is installed.
Further on I have added a complete new chapter with the information available on the net
about the P-3C (& MH-60R), its weapons and sensors (a note on the MH-60R, as stated in
the game manual, the real MH-60R doesn’t have certain capabilities the game MH-60R has,
so as far as the chapters go that deal with the real one, I will include information to weapons
and sensors that are only available in the game -60 as well).

Along the way I want to say Thank You! to the contributors to this document: Smuook, Beer,
STGChamby and JSteed. Especially the first two helped and teached me a lot, when all I
knew about the P-3C was that it’s a big airplane, and it’s supposed to hunt submarines.
STGChamby helped out with the Sound Gradients and Propagation Paths. Thanks to JSteed
for providing me with the original Sonar Profiles file, that way it was easier to bring them in
another format, and include the information for reference.

Note to our virtual Bubbleheads (I know you read this too …). Stealth is your friend – if you
are ever seen/found by a good Orion or Helo Driver you are pretty close to being dead meat,
unless one of the following happens:

• You shoot down the Orion/Helo.
• The Orion/Helo expands all weapons capable of hitting you (which is a lot easier on
the Helo than on the Orion)
• The Orion/Helo looses contact with you (that’s a good one …)

In other words … You can run, but you cannot hide.

Sensors
Acoustics Station (P-3C - Key “F2” / MH-60R - Key “F3”)

P-3C Acoustics Station

The P-3C Acoustics station is the larger brother of the MH-60R Acoustics station shown on
the next page. It will serve as an example for the handling of both stations. However I will
present the Acoustics station of the MH-60R later on and go into the differences between
them.
Grams
The Acoustics Station gives you access to your most important underwater sensor, the
sonobuoys. As you can see on the image, you have 16 Grams (2x8) available, which means
you can monitor up to 16 buoys in OMNI Mode (marked green) or eight buoys in
DIRECTIONAL Mode (marked blue) or five buoys in ACTIVE Mode (marked red). You will
soon learn to appreciate the NAV map feature, where sonobuoys with a contact within range,
will go “hot” (means they display a red dot in the middle). That is very helpful, especially
when you have to cover a lot of ground with them or you have a lot of buoys out. To be
honest, this is far from reality, because in real life you need to monitor the buoy to notice it
going “hot”, plus tactics that spread the buoys out, like this manual suggests sometimes (if
not all the time), wouldn’t work in real life either. But then, this is just a game. A good idea is,
to try and keep the number of buoys dialed in as low as possible, that way you can easily
switch modes or call up a buoy fast, without having to switch around a lot. Just keep those
buoys that show “hot” and which you suspect have a submarine nearby, dialed in. If you
select channel 00 (marked white) the Gram will show NO SIGNAL and can either be used as
a supporting Gram for Directional/Active Mode or you can dial in a buoy of your choice. In the
search phase you usually stick to Omni Mode to be able to dial in more buoys at a time (if
needed). Only when you have a sniff on one buoy should you go into directional mode with it.

Frequency Alerts
I recommend printing out the Appendix A, as you will need that information during a mission.
The frequency alerts (you have four available – one of them is marked black) basically just
notifies you, that one of your buoys (only dialed in ones) has a line in the Frequency Range
you have set as alarm. It won’t tell you which Gram though. That’s something you have to
find out for yourself. Frequency alerts work even when you don’t have Autocrew enabled.
However, assume you are hunting an Akula-II submarine in a moderate density Environment,
means you have a couple of Freighters, maybe a Tanker or a Trawler and the occasional
military ship around. The Akula-II has 5 frequencies: 50, 125, 320, 1125 & 1886 (This – the
combination of certain frequencies - is called a "class identifier"... it's important to know all
the class identifiers for your target), and you have only four possible frequency alarms
available. If all you want to do is finding the Akula-II then you can simply dial in all 4 lines
according to the Appendix A. You will notice that you can’t dial in anything over 1200Hz,
because that’s the max range of the buoys, therefore you are limited to 1200Hz. That’s no
biggie though, since to see those high frequencies (given that the buoys could display them),
you would have to be practically on top of the submarine. So all you can use are the first four
frequencies anyway. And here comes the other big problem: The Akula-II isn’t the only
platform with the combination of 50 & 125 Hz in its Profile, no Sir – the Fishing Boat,
Powerboat, other submarines and surface ships have them too. And if you are in the
aforementioned environment, chances are good, that your alarms will go off, but not because
you have found the Akula.

Then there is the problem of getting more than one or two frequency lines. You see, most of
the subs are pretty sneaky and if you are lucky you will get the first or even the second
frequency line. If you are good, you will track him and place your buoys accordingly, that will
let you classify him with lines three and four. Anyway, if you use your frequency alarms, you
have to take a look at your tactical situation first. Sometimes you can dial in the lower
frequencies and it’ll work, and sometimes you better start with the 3rd or even 4th frequency
as alarm, or otherwise you end up with a lot of false alarms.

At other times you are out looking for more then one type of submarine. If you want to use
the frequency alarm then you have to decide which frequencies you will go for because all
you have are 4 “slots” for the alarm frequencies.

MH-60R – Acoustics Station

The Acoustics station on the MH-60R is both in DW and the real life a lot more cramped than
the P-3C Acoustics station. Space doesn’t matter for us, but the reduced capabilities do.
Let’s see where the differences are.

The Acoustics station of the MH-60R has only two Frequency Alerts instead of four on the P-
3C, however the handling is the same. The more important restriction is the number of
displayable grams. Unlike the P-3C the MH-60R only has 4 displayable grams – no more and
no less. This means that you can only monitor one DICASS in ACTIVE mode (remember,
you need three grams for that – one for the actual display and two as support) or two buoys
in DIRECTIONAL mode (you need two grams for that – one for the display and one as
support) or four buoys in OMNI (or four BT buoys at the same time) mode.

While this might sound like a hefty problem at first glance, you have to realize that the buoys
are only your secondary sensors on the MH-60R. The primary sensor for the MH-60R is his
dipping sonar, which is nearly as capable as a towed array from a submarine or the FFG and
can actually reach much farther down then the VLAD Deep, your deepest diving sonobuoy.
Sure, you can use the sonobuoys just like in the P-3C, but you have a lot less of them and as
you have already seen, it’s a lot harder to keep track of them in the MH-60R. So be patient
the dipping sonar station on the MH-60R will be discussed shortly.

Sound Gradients and Propagation Paths
In this game there are 3 distinct ocean environments modeled: Bottom Limited, Surface Duct
and Convergence Zone. Depending on the graph you get on your BT buoy (P-3C, MH-60R,
FFG) or XBT Probe (All Submarines) you can determine the actual Sound Speed Profiles
(SSP) meaning that you have Positive, Negative or Isothermal conditions.

BT Gram Display

The image above shows the return of a BT buoy in deep water. As you can see, the layer at
the place where the buoy was dropped is at 462ft which is marked graphically (red) and
displayed in numbers (blue). Important here is not only to know where the layer exactly is (in
this case 462ft), but what general conditions you are operating in – which you can see in the
graphical display - to determine probable distances to target. As explained later in this
chapter, depending on the SSP in the operating area you might discover contacts out to 30+
nm (only with the LwAmi Mod – Stock Dangerous Waters has a hard cap on ranges of 7nm).

Layer depth is defined as max sound speed at max depth above the thermocline. The
important thing to remember about sound is that it is lazy and will seek an area of low sound
speed. In the above example, sound originating above the layer will tend to be trapped in
that area or duct. If your sonobuoy is shallow (above layer) and your target is deep (below
layer), the chances of a detection are minimal.

Along with this chapter consult Section 5 - Training, pages 5-3 to 5-19 in the Dangerous
Waters manual to learn about things not mentioned in here but necessary for game play.

The Sound Velocity Gradients tell you about your environment and if you know how to read
them properly you will know how to most effectively employ your sonobuoys. The rest of this
chapter deals with the various SSPs, how they look and how they will affect your detection
efforts.

Generally it is advisable to try and place your buoys on the same side of the layer as the
target submarine. You achieve this by first placing buoys on alternate sides of the layer, once
you detect the sub on one of them you know if he is above or below the layer and thus you
can concentrate your buoys on the right side. However never forget that the sub can always
change depth and therefore cross the layer.

Gradient consists of sound speed either decreasing (image 1-2) or increasing (image 1-1) at
a constant rate with growing depth. In regard to the sound waves this means they either
bend toward the bottom or toward the surface. In the case of an isothermal environment, the
sound speed is constant from the surface to the bottom with little or no change. An example
of isothermal would be the Persian Gulf. The entire water column acts as a duct with sound
propagating in all directions. Sound will primarily be bounded by the two physical barriers of
the surface and the bottom experiencing loss at all interactions.
