The history of ship design has been influenced by factors such as sea, wind and weather conditions, global conflicts, war strategy, and technological advancements. Ship design involves specialists with diverse requirements, and the use of software has made the process more efficient, effective, and safe. The Digital Revolution has significantly improved the efficiency, effectiveness, and safety of ships. Designing a ship involves a combination of theoretical analysis and empirical data gathered from past successful designs. It is an iterative process that must meet various techno-economic requirements. Currently, China, Japan, and Korea are the primary constructors of merchant ships. However, classification societies are crucial in ensuring a ship's structural strength and safety. The most important stage in ship design is the concept design phase, where calculations are used to translate the mission or ship owner's requirements into naval architectural and engineering characteristics. Despite the progress made, ship design remains a challenging task, and naval architects and marine engineers must continue to refine and improve their methods to meet the industry's constantly evolving requirements. Research and development along with navy requirement, are play important role in warship designing and construction. It’s an analytical paper which discusses the amazing technological development and wonderful constructional skill in war shipbuilding along with future technology which will influence entire shipbuilding.
