German WW2 submarines could generally stay underwater for 24 to 48 hours using battery power alone. The actual time depended on their activity level and battery capacity. For longer durations, submarines used a snorkel system to intake air while remaining submerged close to the surface.

FAQs & Answers

  1. How did German WWII submarines manage to stay underwater for extended periods? German WWII submarines used battery power to stay underwater for 24 to 48 hours, and a snorkel system to intake air while submerged near the surface for longer durations.
  2. What factors affected the submerged endurance of German WWII submarines? The submerged endurance depended on the submarine's activity level, battery capacity, and availability of snorkel systems for air intake.
  3. What was the purpose of the snorkel on German WWII submarines? The snorkel allowed submarines to intake air while remaining submerged near the surface, enabling extended underwater operations without surfacing.
