Do Submarines Travel Faster Underwater or at the Surface?

Discover whether submarines are faster underwater or on the surface and why.

663 views

Submarines go faster underwater than on the surface. This is because their streamlined shape is optimized for underwater travel, where water resistance is lower. On the surface, submarines face more drag due to waves and air resistance, which slows them down.

FAQs & Answers

  1. What affects the speed of a submarine? The speed of a submarine is influenced by factors such as water resistance, hull design, and propulsion systems.
  2. How do submarines reduce drag underwater? Submarines are designed with streamlined shapes that minimize drag and optimize their speed when submerged.
  3. Are submarines more efficient underwater? Yes, submarines tend to be more efficient underwater due to reduced resistance compared to traveling on the surface.
  4. What is the maximum speed of submarines? Modern submarines can reach speeds of over 20 knots when submerged, depending on their design and power systems.
