Uboat Attack

YOUR CRASH COURSE

Navigate the Atlantic Campaign Map

Plot patrol routes across a dynamic map where convoy lanes, weather systems, and Allied air cover evolve across the war years. Fuel management determines patrol range — push too far into the mid-Atlantic without reserves and the return trip becomes a crisis. Port upgrades between patrols (better torpedoes, radar warning receivers, hull reinforcement) reflect historical U-boat technology progression.

Stalk Convoys and Set Up Attack Runs

Detect a convoy through hydrophone contacts, then maneuver into an attack position ahead of its projected course. Surface running closes distance faster but risks visual detection; submerged approach is slower and consumes battery but preserves the element of surprise. The approach phase can take ten minutes of real-time maneuvering before the first torpedo launches.

Calculate Firing Solutions

Input target range (stadimeter estimation through the periscope), speed (measured by bow-to-stern transit time across the crosshair), and angle on bow (visual estimation of target's relative heading). The TDC (torpedo data computer) generates a firing solution. Fire a spread of two to four torpedoes with spread angles to account for calculation uncertainty — a single torpedo hit might cripple a freighter; a full-spread impact can break a tanker in half.

Dive Deep and Survive Depth Charges

After torpedo impact, crash-dive below the thermal layer and rig for silent running. Destroyer sonar pings intensify as escorts triangulate your position; depth charges detonate in patterns that escalate in accuracy if you maintain course and speed. Changing depth, heading, and speed between charge patterns while managing battery levels and oxygen is the game's most intense sequence.

Complete War Patrol Objectives and Return Home

Each patrol carries specific objectives — tonnage quotas, specific high-value targets (carriers, battleships), reconnaissance of enemy harbors. Returning to port with objectives complete unlocks upgrades, crew promotions, and new patrol zones. A patrol that sinks nothing but survives to report a convoy's position still advances the strategic layer, rewarding prudent captains alongside aggressive ones.
