China Shipbuilding Corporation has developed high pressure-resistant hulls for submarines since beginning a research and development program a year ago, according the company. The success in building the pressure-resistant hull section for the main propulsion motor, one of the major parts of a submarine, has allowed the company to move forward in its bid to secure orders to build conventional submarines for the navy. China Shipbuilding, with technical assistance from the Joint Ship Design Center, has been trying to upgrade its shipbuilding capabilities in view of winning orders to build diesel-powered submarines for the navy.
The building of the hull section for the main propulsion motor marked the completion of the first stage of development of the company's submarine-building program, dubbed the "Hidden Dragon Project." In the second stage of the project, the company will focus on internal outfitting work, such as piping, which will take another three or four years to complete. These efforts to build submarine parts and components is also in line with the government's policy of promoting domestic construction of warships, according to the company.
