Remaining empty pennants left after all of the last of the remaining batch of 052D gets into service. This may help predict what the pennants and the numbers of the next batch of 052DL/052E will be from the next 5 year building plan.

1st Destroyer Division --- 109 to 114 will all be taken up by 055. During construction of the second block of 055, 112 Harbin (052) and 113 Qingdao (052) will probably be retired in the next coming years, freeing both their names and pennants for new destroyers. The question is whether 115 Shenyang (051C) and 116 Shijiazhuang (051C) will retire early or refitted. If retired early, 115 and 116 will be given to the new block of 055, and both destroyer names will be recycled for use with new destroyers. I do not expect new 052D to be added to this division.

2nd Destroyer Division --- Only one pennant left, 166. This is the pennant of retired 166 Zhuhai, the last Luda. +1 here for possible new 052X.

3rd Destroyer Division -- Only one pennant left, 135. +1 here.

6th Destroyer Division --- 158 and 159 will be left. +2 here.

9th Destroyer Division --- 176, 177, 178 and 179 are left. +4 here but the 9th might get only 055 in the future using the 10X and 11X pennants. So I am not sure if the 9th will be getting any more 052X in the future, and likely not at all.

10th Destroyer Division --- 125, 126, 127, 128 and 129 are left. +5 here.

So all in all, about 9 possible pennants left for 052X.
