There are some indications that the Navy might have decided to procure or may even be in some stage of building a fairly unique (~20,000 ton?) semi-submersible arsenal ship.
This is still in the fairly early stages of rumour + speculation, but there are a few articles and supposedly there have been a few vague references by big shrimps over the years to something like this but wasn't taken that seriously until recently.
But not much about this is really known at this stage, not even designation, not propulsion or even its real configuration or likely payload. It has been referred to on the grapevine as "常潜式海洋攻搜作战平台"...
Far too early to say this thing is real, but the way some of the rumours and info are unfolding makes me think this should be a space to carefully watch if anything comes of it.
