re: PLAN Type 071 LPD & its Landing Craft
I'm guessing it's not a carrier because even if it's a twin screw carrier, wouldn't the prop be at the end of an extended "boom", not right at the end of the hull? Nor a new and larger destroyer. (Sorry, not a ship builder so I don't have the right terms)
LHD is possible but maybe just a specialized civilian ship? Like an oil exploration ship? Someone did say the shipyard produces a lot of cargo/oil transports.
Regardless, it is fun speculating with everyone else here.
