Well I asked grok, and it gathered some data from 20 webpages, like half of those were Wikipedia.
Here's the summary of it's summary. Naval/military vessels.
Notable types and groups: aircraft carriers, destroyers, frigates and corvettes counts these as one category, it isn't wrong, submarines, littoral combat ships, patrol vessels, amphibious ships.
Largest global producers: China (50%), South Korea(28%), Japan(13%) - it sums this at 85%, not 91, so I assume the variation comes from the sources and yearly fluctuation. This is insanely disproportionate. Probably these numbers include commercial ships too - just by the glance I took at the sources.
Other notable producers: US, Russia, UK, France, Germany, Italy, Netherlands, Spain, India (1%), Philippines, Vietnam, Turkey.
Aircraft carrier manufacturing in: China, US, India, France, UK. I'm not sure the latter two still produces them, or they built some and have potential capability to continue if need arises.
