Yes. But that's about it. PLA watching is mostly about collecting and interpreting signs over years. If you see models on defense industry expos, see patents or media articles that suggest a system is being developed, see prototypes through people who spot it coincidently or in media releases, etc, you can conclude that something is coming.
So:
- If we keep seeing a similar CGI ship on PLA or defense industry related material
- See patents or auctions that conform with a new destroyer
- See something hinting at a new destroyer in shipyard commercial statements
- Global times, etc talking about a new destroyer
- See new radars getting trialed
We can conclude that a new destroyer is coming. So the ship we see in these images is a sign we need to record but we can't say a new destroyer is coming.
