China can but you cant & these 5 system are full regiment sized with high potential for 7 More such system in future
1 regiment = 4 battalions
1 battalion == 1 command post
1 Battalion = 16 launchers 64 missile ready to fire and equal number in reloads
4 Battalions = 64 launchers 256 missiles ready to fire and equal number in reloads - 512 missiles and 4 command post
Each S400 battalion has 1 Pantsir-S battalion
1 Pantsir-S battalion = 6 launchers
Each Pantsir-S launcher has 12 missiles RTF and 12 for reload
1 Pantsir Battalion = 72 RTF+ 72 Reloads = 144
1 regiment = 4 S400 Battalion = 4 Pantsir Battalion = 4*144=576 missiles
So 1 full S400 regiment has 512 + 576 = 1088 Missiles in total comprising of 544 RTF and 544 reloads
Based on Indian News of 5 Systems (read regiments)
So 5 full Regiments = 5440 missiles (RTF+ Reloads)
Spare missiles = 560 missiles
Every missile has Pakistani f 16 ,jf 17 name written on it good luck
& You currently have no ballistic missile which can penetrate it nor you will have any for next 2 decade,your only hope is lord China who may help you in your missile program which may further irk uncle sam & buy the way chinese are themselves buying this system
