20th century shipbuilding

20th century shipbuilding saw rapid technological advances, shifting from traditional wooden vessels to massive steel ships driven by steam, diesel, and eventually nuclear power. Innovations like containerization revolutionized cargo transport, making ships more efficient and allowing global trade to expand. Wartime needs spurred developments in military ships, such as aircraft carriers and submarines. The industry also emphasized safety, durability, and environmental standards. Overall, 20th-century shipbuilding transformed maritime transportation, enabling larger vessels, faster travel, and greater global interconnectedness.
