About Silent Shark
Silent Shark is a WWII submarine simulator that emphasizes tactical realism in the Pacific Theater. Players plot courses, estimate ranges, and command a sub using period‑inspired instruments while managing depth, speed, and stealth. The game features a full campaign, dynamic weather, and a scenario editor, catering to fans of naval history who enjoy careful decision‑making under incomplete information.
01 / THE GUIDE
Map Tools and Instruments
The tactical chart includes a compass, ruler, timestamped points, and angle measurements to plot intercept courses. Historical instruments such as the engine telegraph, depth meter, and stopwatch are fully functional. These tools let you calculate angle‑on‑bow, target speed, and bearing before entering data into the Torpedo Data Computer.
- Mark multiple timestamps to compare ship movements.
- Use the ruler for precise angle checks.

Periscope and Hydrophone
The periscope offers 1.5× and 6× zoom, showing a stylized 3D view of contacts within visibility range. The hydrophone lets you hear ships, distinguishing freighters from escorts by pitch. Both sensors feed information to your manual range estimation and targeting process.
- Switch zoom levels to verify mast height.
- Listen for pitch changes to identify escort types.

03 / THE GUIDE
Stadimeter and Torpedo Data Computer
Identify a ship’s mast height, then the stadimeter auto‑calculates distance from the observed angle. Enter angle‑on‑bow, target speed, bearing, and distance into the TDC to generate a firing solution. The TDC includes a Position Keeper, gyro angle, spread, and salvo controls.
- Confirm mast height before trusting the stadimeter.
- Double‑check TDC inputs against plotted data.
04 / THE GUIDE
Sea State, Weather, and Thermal Layers
Visibility and stealth are affected by sea state, weather, and time‑of‑day. Dynamic thermal layers, based on time of day and region, are measured by bathythermographic readings. These conditions require careful timing of dives, surface runs, and torpedo launches.
- Plan attacks during calm sea state for better visibility.
- Take bathythermographic readings to track thermal layers at different times of day.
05 / THE GUIDE
Campaign, Resources, and Progression
A Pacific Theater patrol campaign assigns zones and long‑range mission planning, with fuel, torpedoes, and fresh‑air management across extended patrols. Six submarines unlock through a reputation‑based progression system. Base operations relocate as the war advances, and enemy convoy routes, escort strength, and patrol density evolve over time.
- Conserve torpedoes early to maintain firepower later.
- Monitor fuel levels before committing to long chases.
