You apparently did not follow China's CV program all these years.Maybe it is for the second 003?
If I recall correctly, Liaoning already had her turbine installed when purchased from Ukraine.
So A01 for Shandong, A02 for first 003 and now A03 for the second 003?
Just a guess.
Liaoning did not have power plant when bought. It was just a haul. The Ukrainian even welded the rudder fixed so it could not be steered. It's power plant (boiler and turbine) are domestic product installed in Dalian.
"A03 program" here in the photo is what we call the 003 CV, it is not the designation of a power plant in a series. A03 is 003 or the other way around.
I think you are thinking that 003 is type or class 003. Untill now no body knows for sure what 003 actually means whether it is a class or sequence number of all CVs. Personally I believe it is a sequence number. What is clear is that in all leaked information we see "program/项目", not "class, type/型".
