Covert Shores Surface Recognition Guide To Chinese Navy Submarines
A quick guide to the submarine classes of the People's Liberation Army Navy (PLAN). The chart is intended as a practical guide and does not include every sub-variant.
These recognition guides were a familiar part of the Cold War. In modern times they have fallen out of favor. However in my experience they are extremely valuable and still have a place in the OSINT (Open Source Intelligence) toolkit.
For a fuller guide, my book World Submarines, Covert Shores Recognition Guide, has annotated silhouettes and descriptions:
