Not sure how both of these could be correct. If 003 will have a sister ship that ship will be 004 and the CVN will be 005. BTW this whole nomenclature thing is similar to the 001A vs 002 debates of yesteryear, though in this case if there is a sister ship I feel the nomenclature tension will be even more exacerbated because both CVs will probably be much more similar to each other than the Liaoning is to the Shandong.Both that statements are correct: 004 is the first CNV and 003 will have a sister ship
I think I might have already brought this up before, but I wonder if for the specific case of carriers, the 00X designations would more appropriately be preceded by "Project" instead of "Type", as in Project 001 and Project 002, which at least in English gives more room for each carrier to be its own thing than "Type" which refers to an entire class of ship. If 003 and 004 are sister ships they would be the same type and yet they should still be called "Type 003" and "Type 004"??? Doesn't make sense to me.
