I thought 055 will take a a little longer to build because it is the first hull of her class, but from what pop3 said it won't matter much since he is talking about breaking speed record here.
When people kept asking pop3 about 055. His answer:
Don't be impatient, you will see 055 sooner or later. Because the design process for 055 takes time due to China started late.(maybe he meant large DDG/cruiser building?) The whole project design process took 5 years not including early pre-research after project approval and initiation. But as long as there is founding the construction speed for 055 is not a problem. Besides, the 055 test cycles were very short, we might actually see 055 breaks the speed record for building modern DDGs. Of course.. that's a possibility only.
