ABSTRACT:
Submarines with air-charged cargo holds are provided. The pressurize hull of a traditional submarine's cargo hold is replaced by non-pressurized hull, which lowers costs for transporting dry cargo and solves strength and seal problems raised when providing large openings for hatches. The dive depth of the air-charged cargo submarines is not large, so the pressure and volume of the charged air in the cargo hold are limited. This allows problems associated with ensuring the safety of the crew and properly operating the submarine to be easily solved.
