Silent Shark, a tactical WWII submarine simulator with native Linux support, has been released on Steam.

Players command a US submarine in the Pacific Theater, hunting targets by hydrophone, identifying them through the periscope, and manually building a firing solution with the Torpedo Data Computer (TDC) before destroyer escorts react; the game launches at €14.60 (down from €18.25, a 20% launch discount). A free demo is also available on the Steam page for anyone who wants to try before buying.

Silent Shark is a tactical and realism-focused WWII submarine simulator built around plotting, estimation, and submarine command, set in the Pacific Theater.

Track contacts by hydrophone, work out their course and speed, identify ships through the periscope, estimate range with a stadimeter, and build your firing solution from imperfect information. The game is played on a tactical chart with period-inspired instruments and deliberate controls.

Core Features

Map tools like compass, ruler, timestamped points, and angles help you to hunt for the perfect course to intercept.

Realistic replicas of historical instruments such as the engine telegraph, depth meter, and stopwatch.

Periscope with 1.5x and 6x zoom shows a stylized 3D view of contacts within visibility range.

Hydrophone for tracking ships and convoys by sound - tell the difference between freighters and escort by pitch.

Manual range estimation of ships with a fully functional stadimeter: identify the ship to get its mast height, then auto-calculate the distance by observing the angle to the top of the mast.

Torpedo Data Computer (TDC) with a Position Keeper: Enter angle-on-bow, target speed, target bearing, and target distance to fire torpedoes that will hit their targets.

Destroyer escorts, aircraft, merchant traffic, and convoy encounters. Destroyers act on their own predictions of your location based on a realistic sonar model and their own hydrophone readings.
