The People's Liberation Army Navy is a branch of the People's Liberation Army of the People's Republic of China (PRC). According to Wikipedia:

As of 2024, it is the second-largest navy in the world (behind the United States Navy) in terms of total displacement, and the largest navy per number of ships in active service.

The PLAN consists of large aircraft carriers, frigates, destroyers, and submarines (amongst other types of vessels), and is considered a "blue-water" navy in that it is able to project and deploy its force around the world for long and sustained periods of time.

With substantial territorial disputes amongst almost all of its neighbours in the South China Sea - perhaps most notably with Taiwan and the Philippines - there is a risk that one or more of the PLAN's vessels may be lost at sea; this could be due to warfare, or perhaps even accidental loss.

CNA recently provided a clarification on a PLAN nuclear-submarine which was allegedly sunk last year:

The British "Daily Mail" reported in October last year that the Chinese Communist Party's Type 093 "business-class" nuclear submarine sank in the Yellow Sea in August last year. Cai Mingyan, Director of National Security, said today that the Type 093 commercial-class nuclear submarine was not a serious shipwreck, but there were some accidents, and the location of the submarine was "all in control".

Will any PLAN vessel be sunk by 2030?
