Show HN: Silent Shark – tactical map-based WWII submarine sim
Plot bearings, estimate target motion, and turn imperfect reports into an intercept.
Manage depth, speed, visibility, sea state, and the danger of being detected.
Identify ships, estimate range and angle-on-bow, then build the solution in the TDC.
Run patrols through an evolving war shaped by radio intelligence and historical events.
Measure mast height to derive range. Manual, fast, and error-prone.
Hide beneath temperature gradients based on actual WWII bathythermograph readings.
Use period-inspired controls for speed, course, depth, observations, and fire control.
Time of day, haze, weather, and sea state all affect detection and attack.
iOS, iPadOS, and Android versions are planned; release timing will be announced separately.
The 1.0 release brings the full Pacific campaign, patrol progression, lifeguarding missions, cribbage, and 32 achievements.
