What is the modularity of warships?

Modular design is a trend in modern shipbuilding. The "Virginia" class, the latest multi-purpose attack nuclear submarine in the United States, is also built in a modular manner. Modularization is to divide the submarine into several segments. Each segment is composed of modules, sub-modules, components, components and parts. Modules are like independent "building blocks" that can be combined into different types of submarines. For example: installing cabin modules that can launch ballistic missiles makes it easy for attack nuclear submarines to develop into ballistic missile nuclear submarines; configuring cabin modules that can accommodate special operations personnel so that nuclear submarines can achieve the transport capabilities of special operations submarines; and also Pressure shell module, non-pressure shell module, command and control module, weapons processing module, auxiliary machinery cabin module, residential module, command platform enclosure module, etc.

The planning, design, construction and service life of ships are as long as 30 to 40 years, and it is inevitable to improve and update them during this process. Although due to the continuous development of technology, when a ship is refitted after serving for several years, the technical parameters of the new equipment may be different from those originally expected, which increases the difficulty of refitting to a certain extent. However, due to the module Due to the characteristics of modernization and the advance consideration of the upgrading of important equipment and systems during design and construction, margin for replacement can be reserved in advance and the necessary conditions for replacement can be provided in advance.

Therefore, modular technology can not only shorten the construction cycle, but more importantly, it can improve the construction quality and life of the boat, reduce construction costs and life-cycle costs, and is more convenient for maintenance and repair than traditional design and construction models. Modification. There is no definite rule on how many modules are suitable. It depends on different ships and needs. Generally not a lot, so it is mainly allocated by the system.
