Sub Tutorial

Phase I: Sub vs. Sub

Proceed to Exercise Area A (marked by reference points A1-A4) where a simulated Chinese Han class submarine is currently patrolling. Detect and destroy this vessel. When complete proceed at best speed to Exercise Area B. Please slow down before entering area to preserve stealth characteristics.

Tips:

1. You may choose to create an ASW patrol mission in the Mission Editor to accomplish this task.

To do so:

The ASW patrol mission uses reference points to define the area to be patrolled. You will need to deselect the existing reference points and select the area A reference points to be used or define your own area by using the define area function.

You can deselect all reference points by left click drag selecting a box over all reference points (including the Barking Sands Range marker). You'll know they're unselected when they appear to be gray x's.

You should then define the area you want to patrol by left click drag selecting reference points A1-A4 to activate them. You'll know they are selected when they appear as gold diamonds and you see their names in bold white.

You could create your own box by pressing the control key while right clicking the mouse. When the drop down appears select define area and left click drag select the area you would like to create a zone which creates four selected reference points.

Next select add new mission from missions drop down menu at the top of the UI.

When the New Mission dialog appears give the mission a name, select class (Patrol), Select Type (ASW Patrol) and then click the okay button . When the Mission Editor Dialog appears select the mission to edit by selecting your mission name from mission list on the left. You'll know it is selected when the text is highlighted.

Select the checkbox next to USS North Carolina from the Unit Unassigned list on the far right and then click the left arrow button moving it into the units assigned to mission column. Your unit is now assigned to the ASW mission you created.

Click close to complete process of assigning North Carolina to a ASW Patrol Mission.

2. The UI does provide some helpful clues about the environment your submarine is operating in. Your mouse data block displays depth, thermocline (layer) depths and convergence zone range information. The green rings or arcs show the range of your sensors. The larger translucent rings show convergence zones.

3. Review the sensor dialog to learn about the type of sensors you submarine carries and how to best use them.

4. The faster your submarine is traveling the easier it is for an enemy's passive sensor to detect it and the harder it is for your submarine's sensor to detect an enemy submarine.

5. The thermocline is a great thing to have between you and a sensor that might be hunting you.

6. Submarines are assumed to trail their towed array at the same depth as themselves except when they are close to the layer or just inside it. At those locations they will trail their arrays just in or just out of the layer to minimize their counter detection range.

Phase II: Sub vs. Surface Warship

Exercise Area B (marked by reference points B1-B4) is currently being patrolled by a Chinese Luhu class destroyer. Hunt down and kill this ship. When completed proceed at best speed West to Exercise Area C. Please slow down before entering area to preserve stealth characteristics.

Tips:

1. You may choose to create an ASuW Patrol (Naval) mission in the Mission Editor to accomplish this task. To do so:

The ASuW patrol (naval) mission uses reference points to define the area to be patrolled.

Deselect all previous reference points. You'll know they're deselected when they appear to be dull gray x's.

You should then define the area you want to patrol by left click drag selecting reference points B1-B4 to activate them. You'll know they are selected when you see their names in bold white.

You could create your own box by control+right clicking, select define area and left click drag selecting the area you would like which creates four reference points.

Next select add new mission from missions drop down menu at the top of the UI.

When the New Mission dialog appears give the mission a name, select class (Patrol), Select Type (ASuW Patrol (Naval)) and then click the okay button.

If you assigned the sub to a previous mission you'll first need to unassign it from the previous mission and then assign it to the mission you just created.

To unassign a unit from a mission:

· Select the old mission name from the mission column on the left. You will now see the unit in the assigned to a mission slot in the center.

· Tick off the check box to select the unit and then click the right arrow button to move it to the unassigned slot on the right side of the mission editor dialog.

To assign the vessel to your new ASuW mission:

· Select the mission name from the left mission name slot. Tick off the check box next to USS North Carolina in the unassigned column on your right.

· Click the left arrow to move it into the assigned column in the center of the mission editor dialog.

The USS North Carolina is now assigned to your new mission.

2. You will likely detect the Luhu because it is using active sonar. Active sonar is highly effective however it is very detectable and can give your position away when used.

Phase III: Sub vs. Surface Warship and ASW Helicopter.

Exercise Area C (marked by reference point C1-C4) is currently being patrolled by a Russian Udaloy class antisubmarine destroyer with Ka-27 Helix ASW helicopters embarked. Hunt down and kill this target.

1. You may choose to create an ASuW Patrol (Naval) mission in the Mission Editor to accomplish this task. Please follow the same procedures you have used in the last two exercises to do so.

2. ASW aircraft in the game can be employed in a couple of ways to counter submarines.

The helicopter could be assigned to a ASW strike mission which triggers when a sensor detects the submarine. The helicopter will take off and employ it on board sensors and sonobouys to localize the target and then attack using torpedoes or depth charges.

The helicopter could be assigned to an ASW patrol mission at which the helicopter will launch and patrol a designated area using its onboard sensors and sonobouys. When a submarine is detected and localized the helicopter will attack.

3. It is assumed that towed arrays and VDS pods streamed from surface ships always hang just below the layer to benefit from the deep sound channel. Over the layer detections are usually handled by a hull mounted set on the same ship.

Phase IV: Sub vs. Land Target

Destroy the medium building target on Barking Sands Missile Range with 1-2 Tomahawk cruise missiles.

Tips:

1. You can assign your submarine to Strike (Land) mission using the same procedure as mentioned in previous phases.

2. If you would like to manually launch be sure to check the launch parameters of your missiles. Typically you will have to come to shallow depth or surface to fire. In this case it will be shallow depth.
