For number of TEL, in general a Rgt have 3 Batalions ( at less one sure have 4, reinforced ) but how many TEL in ?
Organisation of Chinese missile/artillery others also units are close to Russian/Soviet for historical reasons... in general a battalion want a western battery 6/8 TEL, S-300 8 by ex.
Then about 20 TEL ( 18/24 ) for a normal Rgt with 3 Bat x 5 + 1 independent Bat about 110 TEL can be a good number i think.
Always very difficult in more with China for found Coastal missiles data,TOE/Orbat..
NSF :
11th Coastal Missile Rgt ( 31,32,33,34 bat ), Weihei, YJ-62/C-602
12th Coastal Missile Rgt ( 35,36,37 bat ), Dalian, YJ-82/C-802
ESF :
13th Coastal Missile Rgt ( ? Bat ), Zhoushan-Dinghai- Maoling, YJ-82/C-802
1st Coastal Missile Regt ( ? Bat ), Fujian-Fuzhou , YJ-62/C-602
SSF :
2nd Coastal Missile Rgt ( ? Bat ), Shantou,YJ-62/C-602
46th Coastal Missile Battalion, Sanya,YJ-62/C-602
Eventualy all with YJ-62 ? and maybe now one which have YJ-82 can have new YJ-12 ?
