Offline Modes

Silent Hunter: Wolves of the Pacific has the following single-player modes available.

Submarine School

Game Mode Description
The Submarine School is the games tutorial, a collection of missions teaching you the essentials of submarine navigation and warfare. Four courses (objectives) are offered: Navigation, Artillery (how to use guns), Torpedoes, and Convoy Attack. Completing Submarine School missions is not mandatory, but it gives you a boost when starting a new campaign. Exams can be taken an unlimited number of times, so dont despair if you get a bad grade your first time out. To complete a mission, finish your objectives and then press the Esc key.

Content

Navigation Training
Objective: Reach a designated zone. To control the speed of the submarine you may use the speed telegraph dial (the left-most dial on the interface).You can left-click anywhere in the dial. The dive officer will automatically set the engine speed according to your selection. On the right side of the speed telegraph dial are the speed steps for moving ahead. On the left side of the speed telegraph dial are the speed steps for moving backwards. In the middle lower part of the speed telegraph is the All Stop command. To control the direction of the submarine you may use the compass dial (the middle dial on the HUD). You can left-click on the outer disc of the compass dial to set a new direction for your submarine. The compass will allow you to turn the boat toward a direction and continue in that direction. To control the depth of the submarine you may use the depth dial (the right-most dial on the HUD). You can left-click anywhere on the marked area. The dive officer will automatically set the depth according to your selection. Using the depth dial, you can dive up to 165 ft. Each marking represents 5 ft of depth. You can use the following shortcuts to set various depths: S key to surface the submarine and P key for dive to periscope depth

Sonar and Radar Training

Objective: Detect the enemy convoy. In this mission you will learn to use the radar and the sonar to intercept an enemy convoy.

Convoy Attack Training

Objective: Sink 10,000 tons of merchant ships. This is a training exercise in which you have to engage convoy in combat conditions. The enemy will attack you. Use the submarines capabilities to the maximum. The convoy will move on a NNE course. You start in a good attack position, SE of the current position of the convoy. The sun is setting. Remain submerged and take a general course to NW, perpendicular to the convoys estimated course. Approach the convoy at Ahead Slow to remain undetected by the escorts. The escorts hydrophones have a limited range. Avoid getting too close to them and you will remain undetected. An escorts weak spot when searching a submerged submarine is behind it. The escorts hydrophones cannot detect a submarine behind them because of their own propeller noise. If you find yourself in such a position, you can move fast without being discovered. If an escort has detected your submarine, dive to a safe depth of at least 50 m. When an escort launches depth charges, you should move your submarine with Ahead Flank speed and turn hard to one side or the other. After evading an attack, return to Ahead Slow to remain undetected. Once you pass the escort screen, the best chances to successfully attack with torpedoes a merchant ship are when you remained undetected, within 1,000 yards, and positioned abeam of the target.

Career

The Career mode is also known as the dynamic campaign. In this mode, you perform a series of patrols throughout the course of the war. The length of your career will depend on your performance. A poor player may be relieved from command early, while an excellent captain will be offered the command of a new and better submarine and later retire to a desk job.

Career Menu

In the Career menu you can choose a name, the starting date of the campaign, the starting unit that youll be part of, the type of submarine, the difficulty of the campaign, and the starting renown. Several of the starting options will default to random, allowing you to receive a surprise assignment every time you start a career.

Objectives

Before every patrol, you will be presented with a number of objectives that your commander wants accomplished. As the campaign and the objectives are dynamically generated, there is no telling what each of the patrols may consist of. Your orders may, however, include the following objectives: Patrol area and sink enemy ships. Photo recon of enemy installations. Lifeguard duty in support of air operations. Supply drop to friendly forces. Transport and insert Allied agents or troops on an enemy-held island. Stop at a friendly base. Accomplishing the objectives is not mandatory, in that you are not required to complete them in order to advance in the game. As in real life, sometimes its just not possible to complete a certain action without losing your boat. Remember, though, that an unproductive commander will not be appreciated, so try to bring results as well as keep your boat safe. You are free to engage any enemy targets you encounter before, during, or after the completion of your objectives. To terminate the patrol you will need to sail back to port.

Career Progression

As you complete each patrol in your career, you will receive several rewards for your actions. Renown: This is a measure of your fame as a submarine captain and the influence you have with the commanders of the submarine fleet. The more successful you are, the more renown you gain. You can use the renown to get access to certain improvements for your submarine sooner than they become available to the fleet. You can also use the renown to recruit better-trained crewmembers for your submarine. A few actions that get you renown are: Destroying enemy ships. Destroying enemy planes. Completing objectives. Saving downed Allied pilots. Loss of Renown: It is perfectly possible to lose the influence you have with the commanders and your renown. Possible reasons include: Sinking neutral ships. Sinking Allied ships. Shooting down friendly airplanes. Getting your men wounded or killed. Receiving damage to your submarine.
Promotions: If you are particularly successful, you may be allowed to award promotions to members of your crew. If you have sufficient renown, you may even get promoted yourself. Medals: If you are particularly successful, you may be allowed to allocate medals to members of your crew. It is also possible for you to receive such decorations. Qualifications: Whenever you promote a crewmember that reaches Petty Officer status, you will be required to assign him a qualification. This will improve his skills and thus his efficiency in the submarine, but for best results you should qualify men based on their natural skills.
To save your career during a mission, hit the Esc key. You will then see a menu option to save your career.
Saving, Loading, and Deleting Careers Ending a patrol
To end a patrol, you will have to reach your home base. When youre close enough to the base, a pop-up screen will appear asking if you wish to dock. You do not have to travel the last mile and dock in the submarine pen, though you are welcome to try it.

TBT Station

The Torpedo Bearing Transmitter (TBT) is a large binocular affixed to a special post on the deck of U.S. submarines. Historically it was used in 1943 to help obtain the bearing and range to a target during surface torpedo attacks. In our game, the TBT will be available from the start of the war, simulating the ability of the crew to transmit orders verbally rather than automatically through the rotating post of the TBT. The TBT can be accessed in two ways. In 3D mode, go to the bridge (shortcut: F4) and left-click on the large binoculars that you see mounted in the center. Or, you can press the U key on the keyboard to be transported directly to the TBT. NOTE: This station, like the bridge, is only accessible while surfaced. Function-wise, this station is almost identical to the two periscopes, except that the range-finding mechanics are missing the split image function. Refer to the Periscope descriptions and the chapter on conducting torpedo attacks for further information.

TDC Station

Conducting Torpedo Attacks
One cannot overestimate the importance of the torpedo attack in the training of the submarine officer. To quote the official submarines doctrine of the U.S. Navy, as formalized by ComSubPac in February, 1944: The primary objectives of submarines are enemy ships. The primary weapon of the submarine is the torpedo; the secondary weapons are the mine and gun. A successful torpedo attack requires several steps. It is your duty as captain to ensure that each step is completed. The steps are: 1. Approach and positioning 2. Data collection 3. Sending data to the TDC 4. Tubes selection 5. Attack
1. Approach and Positioning
Your torpedoes are not extremely reliable and easy to use. Before attacking, bring your submarine as close to the target as possible within 1,000 yards for best results. At short range, even if you or the torpedoes are suddenly spotted and the target starts evasive maneuvers, it will be too late for the enemy. Distance is not the only point of interest, however: the submarines position relative to the target is equally important. Generally speaking, the best position to begin your attack would be ahead of the beam, meaning 45 to either side of the targets course. From this point, you will have plenty of time to gather the data required for the attack and still be well placed for a bow or beam shot.

2. Data Collection

To have your torpedoes meet with the target is not a simple feat. Every attack is a complex trigonometric problem that needs to be solved. Fortunately, most submarines of the World War II era were equipped with a Torpedo Data Computer an electro-mechanical device that solves the movement equations and provides you with the data needed for the actual attack. Unlike the TDC onboard other nations submarines, the U.S. TDC does a lot more, but well talk about that later.
The Torpedo Fire Control Problem
Given an initial situation: a target ship moving on a constant, straight course C, at a constant speed S, we need to obtain the course CT on which a torpedo of speed ST must travel in order to reach point (X) at the same time as the target.
The mechanics of torpedoes are such that after leaving the tube, they run a standard straight distance the so-called torpedo reach before making one turn according to the set Gyro Angle to reach the desired course CT. The Gyro Angle is calculated by the Angle Solver part of the Torpedo Data Computer, but requires the following information to be collected on the target: Bearing to target Range to target Angle on bow Target speed To acquire this data, you will have to use one of the two main stations of attack: the Periscope (optic used for underwater attacks) or the Target Bearing Transmitter (binoculars used for surface attacks). Both are equipped with all the tools needed for this task. You can also obtain range and bearing information from the Sonar stack and Surface Search Radar. On lower difficulty settings, all data will be acquired automatically by the game whenever your crosshairs pass over a viable target. On Historical settings, however, each step will need to be completed by you. Measuring Range Determining range to a target of a known height is a simple problem, so the first step to be undertaken in any attack is identifying the target. Bring up the recognition manual (shortcut: M key) and flip through it until you find a match with the one you are looking at through the optics. This is not an easy task, but focusing on the defining elements of the ship (bow and stern shape, number and disposition of masts, number of turrets) you should be able to get a close match.

Once satisfied, check the empty box present on the manuals page. This will identify the ship in question and automatically enter its mast height the tallest object on the ship into the stadimeter. Hint: Its easier to identify a ship when looking at it from abeam (90 to its side) as it presents the full profile, much like in the manual. Click the icon on the attack data tool, which will switch it to the correct mode.
As you have the targets real height from the ID book, all you need to do is read its apparent height (as angle alpha) from the periscope or TBT. Both optics are fitted with marked reticles for this task. The periscope comes equipped with a split-image stadimeter to automatically measure it, while the TBT only simulates the measuring process through the usage of a moving line index.
The meaning of the reticle marks is outlined in the table below: Optic Used (Zoom Level) Periscope (Low Magnification) Periscope (High Magnification) TBT (7x) Small MarksLarge Marks 1 0.25 (015) 0.2 (012) 1
To use the stadimeter, first lock the target. Next, press the
icon in the upper left part
of the Attack Data tool. Your mouse cursor will be captured, and vertical mouse movement will be used to displace a second image of the target instead. Raise it so that it touches the top of the original image. In other words, you need to have the waterline of the target, as viewed in the second picture, touch the masthead of the first one. All through the process the stadimeter will automatically calculate the range to the target, based on the angle displacement between the two images. When you are satisfied with the results, leftclick and the range will be saved. You can then use the Send to TDC button to correct or set the target data. Should you desire to calculate the range yourself, the formula you should be using is:
When intelligence on a target is unavailable or it is impossible to obtain an accurate identification, you should estimate the height of the masthead or another significant feature on the superstructure: Count the number of decks that are seen above the main deck. Add the number of decks that would cover the visible freeboard. Multiply the obtained number by 8, which is the average height in feet of a deck The result gives you the height of the tallest point on the bridge structure. You can use this as a yardstick to approximate the height of the masthead on average 2.1 times the obtained figure. If the masthead appears shorter, use 1.7 or 1.8 as a ratio instead. By exercising on targets of known height you should be able to obtain an approximation good enough for a firing solution.

Angle on Bow

The Angle on Bow (AOB) is, simply, the bearing on which the target ship would observe your submarine. It is easier to approximate relative to your boat and is used to define the ships course relative to your own.

To enter AOB for your target, first switch the attack data tool to the appropriate section, by clicking the icon. Entering the desired value is as simple as dragging on the external ring
of the dial (representing the target ship) to put it in the correct position relative to your submarine, which is represented by the fixed index in the 6 oclock position. The question is, what should the desired value be?
There are multiple methods to judge AOB on a target. The quickest method is through visual observation. This is obviously quite inaccurate, but using the recognition manual AOB page you may come up with a reasonable value quite fast. A more time-consuming but also more accurate and difficult method is to adjust your heading until the lateral separation between your ships remains constant and you are both heading the same way. At this point, you have matched course to target. In other words you are traveling along parallel courses. Its easy to determine AOB at this point, using the following formula. AOB = 180 bearing
One of the most critical parts of the firing solution is to determine the target speed. In the game, there are two methods for doing this. The quickest method is to simply guesstimate the value by checking the target, the bow wake, and the intelligence info that you have from the recognition manual. Estimates by the sonar man also come in handy here. The more precise but also more time-consuming method is to take multiple sightings (range + bearing) of a target over a period of time. Using this data and your own speed and course, you can determine the targets speed. An automated method is implemented in the game.
To begin the process, left-click on the clock icon on the data tool. This will take the first sighting and begin counting the time. It is best to have the target locked at this moment. When satisfied with the expended time longer is better left-click again. This will conclude the measurement and display the results. As always, check them if you are satisfied with your approximation. Hint: This method of finding target speed is heavily dependent on the accuracy of your range estimation. If you are getting speed results that are off the scale, recheck the range.

Cooperative Mode
In cooperative multiplayer a maximum of four players over the Internet and eight players on a LAN, each commanding a submarine, must work together toward the completion of a common set of objectives. Enemy ships are controlled by the computer. The main objective for the players is to sink a specific amount of tonnage in enemy shipping, but there may be specific objectives depending on the mission.

Adversarial Mode

Adversarial mode is similar to the Cooperative mode except for the fact that one player the server operator controls the escort ships present in the scenario. Your objective during the game is to stop the submarine players from achieving their goals in the set time of the mission. To accomplish this, the player uses the sensors and weapons onboard the escorts, locating, attacking, repelling, and, hopefully, sinking the submarines.

Facts about U.S. Submarines in World War II
Submarines comprised less than 2% of the U.S. Navy during World War II. U.S. submarines sank over 30% of the Japanese navy. In fact, U.S. submarines sank eight Japanese aircraft carriers. U.S. submarines played an important role in the virtual strangling of the Japanese economy. U.S. submarines sank almost 5 million tons of Japanese shipping. 200 U.S. subs sank 201 Japanese warships and 1,113 merchant ships. 211 subs were built with an operational peak of 182 in 1945. The U.S. lost 52 subs with 3,503 crew. Gato-class subs were mainly used early in World War II. Later, they were joined by similar Balao-class subs.
