China says it leads the world in submarine power systems

China's 039B Submarine

China’s 039B Submarine

The following is based on a translation from a report in Chinese media:

Mil.qianzhan.com says in its report that People’s Daily mentioned China’s new hot air engine for submarines, that has a power output 117% higher than imported engines.

This makes China the leader in such power systems.

According to the website, the new engine was developed by No.711 Research Institute, which specialises in research and development of various types of power systems for China’s conventional submarines.

The one with the highest technology is the AIP power system used in China’s Type 039B submarines.

The AIP engine China uses in its Type 039B submarine is a Stirling Engine imported from Sweden in the 1980s.

According to the report, Sweden markets various kinds of Type 4-275 engines including 75kW and 110kW ones, but it only sells 75kW ones in the international market now.

Sources say that at that time China imported a single 75kW Stirling engine. China succeeded in copying the engine and installed China’s homegrown version in its 039B conventional submarines.

On the basis of the imported Stirling engine, the special engineer team at the No. 711 Research Institute have spent almost 10 years in developing a brand new type of engine entirely with China’s own intellectual property.

The website says the new power system will be used in China’s new conventional submarines.

  1. Mere claims! All of China’s military hardware are not battle-tested. In my opinion, one of the reasons the U.S. wants war with China in the South China Sea is to test the capabilities of it’s weapons viv-a-vis China’s. Lately, China has been bragging about it’s latest drones, missiles, subs, etc. It is clearly just the reaction of somebody who is scared. China knows that if the U.S.were to send the 7th Fleet to the area, PLAN would have no other option but to back down.
