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.

The second edition of the book will be published within a few days to mark the 25th anniversary of Tiananmen Protests All the parts in the first edition remain in the second edition with a few changes due to information available later and better understanding. There are also some changes for improvements of style. The new parts are Chapters 12-19 on events in China after the first edition was published: The fierce power struggle for succession between reformists and conservatives; Xi Jinping winning all elders’ support during his mysterious disappearance for 2 weeks in early September, 2012; and Xi Jinping Cyclone. Chan Kai Yee's new book: SPACE ERA STRATEGY: The Way China Beats The US An eye-opening book that tells the truth how the US is losing to China. The US is losing as it adopts the outdated strategy of Air-Sea Battle while China adopts the space era strategy to pursue integrated space and air capabilities: It is losing due to its diplomacy that has given rise to Russian-Chinese alliance. US outdated strategy has enabled China to catch up and surpass the US in key weapons: Hypersonic weapons (HGV) that Pentagon regards as the weapon that will dominate the world in the future. Aerospaceplane in China’s development of space-air bomber that can engage enemy anywhere in the world within an hour and destroy an entire aircraft carrier battle group within minutes. Anti-satellite (ASAT) weapons, anti-ASAT weapons, stealth aircrafts, drones, AEW&C, etc. The book gives detailed descriptions of China’s weapon development based on information mainly from Chinese sources that the author monitors closely. U.S. Must Not Be Beaten by China! China is not a democracy. Its political system cannot prevent the emergence of a despotic leader or stop such a leader when he begins to bring disasters to people. A few decades ago, Mao Zedong, the worst tyrant in world history did emerge and bring disasters to Chinese people. He wanted to fight a nuclear war to replace capitalism with communism but could not bring nuclear holocaust to world people as China was too weak and poor at that time. If a despot like Mao Zedong emerges when China has surpassed the US in military strength, world people will suffer the misery experienced by Chinese people in Mao era. China surpassing the US in GDP is not something to worry about as China has the heavy burden to satisfy its huge population, but China surpassing the US in military strength will be world people’s greatest concern if China remains an autocracy. US people are of much better quality than Chinese people. What they lack is a wise leader to adopt the correct strategy and diplomacy and the creative ways to use its resources in developing its military capabilities. I hope that with the emergence of a great leader, the US can put an end to its decline and remain number one in the world.

  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.
