The 6th and final 052C Destroyer 'Xi'an', pennant no: 153 was commissioned on the 9th February 2015, according to a Chinese report.
After what appeared to be a lean year in 2014, regarding major surface combatants being inducted into the Chinese Navy.............in the last few weeks we have had a few 052C Destroyers, and 054A Frigates being commissioned.
Next up, should be the 2nd 052D.........which I imagine should be commissioned soon!
