Penetration

This is a display at the US Navy Museum. It’s a 26 inch thick piece of armor from a Japanese Yamato class battleship. The hole is from a US Navy 16 inch gun.

  1. Classical ballistic penetration depends on two things: Velocity and sectional density.

    A 16 inch gun appears to have both.

  2. I believe that was a section of test armor, not something actually installed. Both the Yamato-class ships lie on the ocean floor after fierce combat. The number of torpedoes and armor piercing bombs required to put them there is rather impressive.

  3. The super heavy US AP punched way above their weight. The effectiveness if these shells is one of the reasons we never went bigger than 16″

    Japanese armor composition was also inferior to US and British variants.
