How are 20 century ships builth?

Answer 1

In the 20th century, ships were built using a combination of traditional shipbuilding techniques and emerging industrial methods. Steel became the primary material, with ships constructed in large shipyards using assembly line principles. Sections of the ship, or blocks, were fabricated separately and then assembled in dry docks. Advancements in welding technology, machine tools, and computer-aided design greatly improved efficiency and precision in ship construction.
