Damage

Locations

When your sub takes damage, that damage is applied to a specific location on your sub, which will impact one of your sub's systems.

Location	Effect of Damage
Flooding	How fast your sub sinks. This is the most important damage, as it's the one that will kill you.
Periscope	Limits your perception range when at periscope depth.
Dive Planes	Limits your dive/ascend speed.
Rudder	Limits your turn rate.
Batteries	Reduces the amount of battery power you can store; in turn, limits how long you can move while underwater.
Engines	Reduces your maximum speed while surfaced.
Motors	Reduces your maximum speed while submerged.
Bow Torpedo	Reduces the number of available bow torpedo tubes.
Aft Torpedo	Reduces the number of available aft torpedo tubes. To 0.
Deck Gun	Increases the time it takes to reload.

Indicators

Each damaged system is represented by a "damage indicator" on the right side of the screen. The indicators give you information on the state of the damage.

The colored bar shows how badly damaged the system is. The smaller the bar, and the more red its color, the worse the damage is to that system. If the bar is completely gone, then that system has been destroyed, and can not be repaired by your crew; if you're playing a War Patrol, you will need to find a Resupply point to replace that system for you.

The left-hand light will be yellow if the system can be repaired, red if it cannot. If the system hasn't been destroyed (there is still some bar shown), then it cannot be repaired because that system is outside the sub and you're submerged; you'll have to surface to repair it.

A spinning wrench will be over the light of the location that is currently being repaired.

Long-press on an indicator to bring up a 3D view of your sub highlighting the damaged location and giving a description of the damage and its effect.

Repairing

Whenever your sub is damaged, your quick-thinking crew will automatically begin repairs. If multiple systems are damaged, they will prioritize the order in which those systems are repaired.

You can override that priority by tapping on the damage indicator for the system on which you want them to focus their repair efforts.

If you tap on a location that can't be repaired (either because it is destroyed or because you must surface to repair it) you will hear an error sound.

Flooding

Your top priority for repair should always be flooding; if your sub is flooding, you're sinking. The worse your flooding damage, the faster you're sinking. If you don't repair it quickly enough, you will sink below your crush depth and implode.

By default, Flooding is always the highest repair priority.

Crush Depth

Your Type VIIC u-boat is technically only rated to 200 meters, but in reality it can go deeper than that. If you long-press the Dive button, you will immediate crash dive to 210m. You can then keep tapping Dive to go deeper in 10m increments. But somewhere between 230m and 295m, your sub will implode…

The actual crush depth is set randomly at the start of each encounter (since it can vary depending on water temperature, salinity, currents, etc.), so if you safely dive to, say, 250m once, you can continue to safely dive to 250m for the remainder of that encounter.

Why take the risk? Because the deeper you go, the harder it is for the enemy to find you and the easier it is to escape.
