parts

10 mechanics, as Silent Hunter III does them

core · 2

conflict & defense

Military operations

The campaign engine generates convoys, destroyer escorts, and task forces in assigned patrol grids, and the player chooses targets and approaches.

operation & procedure

Procedural checklists

Manual targeting requires identifying a vessel's class and nationality and computing its speed, angle on the bow, and gyro angle before setting torpedo depth and spread.

supporting · 8

agents & behavior

Agent skills

Crew members carry rank, experience, morale, and decorations between patrols.

progression & goals

Career ladder

A career begins at the rank of Lieutenant, Jr., with a U-boat base assignment between 1939 and 1943.

environment & ecology

Day-night cycle

control & automation

Delegation to AI managers

With manual targeting off, a Weapons Officer computes the firing solution.

information & legibility

Fog of war

physics & materials

Projectile ballistics

Torpedoes run at a set speed, depth, and gyro angle toward an intercept computed from target speed and angle on the bow, so a bad solution misses.

environment & ecology

Weather

core loop

receive a patrol grid -> transit under time compression -> detect contacts -> identify the target and solve speed, angle on the bow, and gyro angle -> fire torpedoes -> evade escorts -> return to base and promote crew

design notes

The campaign engine generates convoys, destroyer escorts, and task forces in each patrol area rather than scripting engagements, so a career starting between 1939 and 1943 is a sequence of unplanned encounters. Realism settings scale the procedure: at the hardest, the player identifies class and nationality and computes speed, angle on the bow, and gyro angle; with manual targeting off a Weapons Officer solves the problem while approach geometry still matters. Crew members persist between patrols with rank, experience, morale, and decorations.
