Submarines & Depth
Depth is the submarine's armor.
| DEPTH STATE | DETECTABILITY |
|---|---|
| SURFACED | Fully visible on every channel |
| PERISCOPE | ~70–80% harder on visual/infrared; somewhat harder on sonar/radar |
| SUBMERGED | Invisible to radar/visual/infrared; sonar (full) and acoustic/magnetic (reduced) still work |
