But, when they do the pressure hull fails violently and catastrophically. Most likely death is due to traumatic injury. They’re probably crushed by the hull, internal equipment or the force of seawater coming into the breached hull. There’s no time to drown.

How do submarines avoid crashing?

Avoiding collisions in shallow water requires different skills. Submarines are fitted with bottom-sensing sonar but mostly rely on maps of coastal waters. They navigate using an imaginary “pool of errors”. “The longer you are without a proper fix then your pool of errors expands,” says Tall.
