Hi wispywood2344 and Anonymous thank you for your comments of July 4, 2021 and
July 6 respectively. These comments are below the article Chinese Submarines: Big Modelling Intelligence Gap of July 1, 2021.
I'll assemble most unique information on China's nuclear and conventional submarines behind the paywall, ie: after July 31, 2021.
1.I will be using the NATO reporting name system which assigns Chinese dynasty names to Chinese submarines. Hence I don't talk of confusing "Type 039" numbers in identifying Song class or Yuan class conventional subs. Use of NATO reporting names removes the power to control and confuse from the potential enemies - be they Russia or China.
2. Instead of the three dimensions of batteries (height, depth and width) I am going to rely more on comparative displacement, in metric tonnes, between submarines. Of course their major components, like batteries, will also be totalled into metric tonnes.
