Sonar Hunt

Sonar Hunt is a submarine stealth game built on a real acoustic model. You command a diesel-electric boat in a hostile strait. You cannot see the enemy — you can only hear them. LISTEN FIRST Every ship makes noise, and so do you. The faster you go, the louder you are and the less you hear. The passive sonar gives you a bearing and a signal on the waterfall display, never a range. Stay slow, stay quiet and let the contacts come to you. BUILD THE SOLUTION Mark a contact and manoeuvre. Every leg you sail changes the bearing rate, and the firing solution grows from real geometry — sail straight and it stays blind. When the solution is good enough, fire a torpedo that runs at 45 knots and homes on the target. USE THE LAYER Cold water below the thermal layer bends sound away. Hide under it after a shot and the escorts lose you — but you lose them too. An active ping reveals everything at once and tells every escort exactly where you are. SURVIVE THE ESCORTS Corvettes and destroyers listen with the same physics. Get noisy and their suspicion rises, they start a search pattern and attack with depth charges. Watch the battery, the hull and the crush depth. TWELVE PATROLS AND AN OPEN HUNT Twelve operations along the strait, starting with a coached first patrol. Each has three mastery stars: complete the patrol, exit undamaged, never use the active ping. Free Patrol opens after patrol four with endless convoys and a tonnage record. REFIT YARD Earn commendations and refit your boat: quieter screws, a better sonar array, bigger battery cells, torpedo guidance and hull plating — every card shows the real before and after. Three hull classes: Coastal, Ocean and Long-Range. SERVICE RECORD Total tonnage, confirmed kills by class, the longest silent run, the deepest dive, patrol ribbons and five ranks from Ensign to Captain. Everything is personal and stays on the device. OFFLINE AND PRIVATE No network permission, no advertising, no sign-in and nothing to buy. Your progress stays on your phone.
