Unbuild Post-war Battleships

As a follow-up to my recent KZbin video about United States' War Plan Orange, I have created a further video about the battleships and battlecruisers that were designed during and after World War I but never built or completed as designed.
The ships that I have included are the Japanese Navy's Tosa-class battleships, Amagi-class battlecruisers, and Kii-class battleships, the Royal Navy's N3-class battleships and G3-class battlecruisers, and the United States Navy's South Dakota-class battleships and Lexington-class battlecruisers
