China is building a new diesel-electric submarine
Chinese diesel-electric submarine (DEPL) of a new type is being built at a shipyard in Wuhan (Hubei province), according to the magazine "Canvas Defense", published in Hong Kong.
Experts note that one of the unusual characteristics of the new Chinese diesel-electric submarines is the relatively high value of the angle between the cabin and the submarine hull, which makes it look like the German submarines of the 212 project. The main objective of this hull form is to increase the hydrodynamic properties of diesel-electric submarines during underwater and surface voyage, as well as to reduce the noise caused by water impacts on the submarine hull.
According to the magazine's experts, one of the most important aspects of modernizing the submarine was the installation of new weapons. According to the publication, the PRC has developed a multipurpose missile for launching from submarines at increased subsonic speed based on the Russian anti-ship missile (ASM) Club-S. It is assumed that this Chinese weapon is installed on the new diesel-electric submarine. Experts believe that it is used to equip Type-039B submarines, which China has been serially producing for a certain period of time.
Analysts at Canvas Defense say that the new diesel-electric submarine is most likely a significantly upgraded version of the Project 039B submarine (Type 039B), so they designated it as Project 039C. Over the past 10 years, the PRC's naval experts have repeatedly published very detailed reviews of the advantages and disadvantages of the cigar hull of submarines. In this regard, experts note that the PRC has probably made a decision to design a cigar-shaped rather than a drop-shaped body of a new diesel-electric submarine. Also, the Chinese could install X-shaped rudders.
Diesel-electric submarines "Type-039B" are equipped with air-independent power plants (VNEU). It is assumed that the Type-039S submarine is equipped with a similar VNEU.
The experts of "Canvas Defense" believe that the question of replacing the production of "Type-039B" with a modernized version of the new submarine will become urgent in the near future. As an indirect argument, they point out that since 2012, no information has been received about the production of Type-039V diesel-electric submarines at the shipyards of Wuhan or Shanghai.
