I agree........looking at the building times of the 054A............it does appear that by going past 054A outfitting times, the latest 054A's are taking longer than usual to complete.
Basically, as an average, previous 054A's have taken a year from launching to commissioning.
As of this moment there are 16 active 054A's in the fleet.
The 17th vessel 'Yangzhou' was launched in April 2013.....so this vessel is well overdue for commissioning, and the 18th and 19th vessels were launched in Sept last year.
Hopefully, the 'Yangzhou' gets commissioned soon, before the end of year!
I also wonder when we are going to see the 6th 052C enter service as well, as that is taking an age as well.............it was also strange that a major surface combatant such as the 5th 052C apparently entered service in the summer of this year, but unlike the news on 056 commissionings, there didnt appear to be any news on Chinese military sites whatsoever of this event taking place (unless someone here can show me an article)!
.........and in all this we were all taken by surprise when the 1st 052D was commissioned, in super fast time.
Someone needs to tell the Chinese Navy to stop messing about.........eh?
