Why can't there be women in the submarine?

The space of the submarine is very narrow, which brings inconvenience to life and work, and women are more sensitive to the environment, and it is easy to have various problems if they stay for a long time.

There are many kinds and shapes of submarines, ranging from fully automatic or small civilian diving detectors operated by one or two people for several hours to Russian typhoon-class nuclear submarines that can carry hundreds of people and snorkel continuously for 3-6 months. According to the volume, it can be divided into large (mainly military), medium or small (pocket submarines, submersibles) and underwater automatic mechanical devices.

Submarines are also used for non-military purposes, such as marine scientific research, property rescue, exploration and development, scientific exploration, equipment maintenance, search and rescue, submarine cable maintenance, underwater tourism and academic investigation. Submarine is a recognized strategic weapon (especially in disarmament or arms expansion negotiations), and its research and development requires high comprehensive industrial capacity, and only a few countries can design and produce it by themselves.

So far, submarines are propelled by manpower, which limits the development of submarines. At this time, the steam engine has been invented and applied to railway transportation and surface ships. The application of steam engine in submarine promoted the development of submarine power plant. With the continuous efforts of submarine designers, a modern submarine powered by machinery finally appeared.
