Because of its rich resources, vast space, great economic value, scientific research value and ecological environment value, the deep sea has become a battleground for all countries in the world in the 2 1 century.
The vastness, connectivity and concealment of deep-sea area, as well as the reality and huge economic potential of shallow exploration, make it not only show an increasingly important strategic position in safeguarding national security and development, but also become the sixth important strategic space after land, sea, air, sky and electromagnetism.
The importance of the deep sea
The uniqueness and advancement of deep-sea battlefield space triggered the development and transformation of deep-sea military, which was realized through new technologies and means, and gradually changed the strategic situation of military struggle. All maritime powers are stepping up the development of deep-sea technology and deepening its application in the military field, with the intention of occupying the commanding heights and initiative in the new deep-sea space.
Due to the attenuation characteristics of electromagnetic wave propagation under water, the deep-sea base located in the deep seabed hundreds of meters or thousands of meters deep is difficult to be monitored by satellites and has strong concealment.
