Vietnam's tiny frigate cannot carry this missile, so they must place it around its coast line.
But the problem is that no PLAN ship will get close to 300km of the Vietnamese coast, while the new PLAN DDG can bomb the Vietnamese coast from 2500km away.
Meanwhile, after a first wave of electronic attack, all those missiles and radars will become useless.
Hey, we never plan to occupy Chinese land ...
You dreaming about electronic attack ... while Vietnam has the state-of-art radar systems ...
could easily handle all J-series, J20, J31 ... even US stealth
harden by real experience against US electronic welfare for several years ( don't argue that Vietnam step in place for anti-electronic welfare).
Vietnam even could anti-radar counter-strike to China naval bases or on board Chinese warships
For coastal defense : those are mobile systems, and why we must attack other ships out of 500km range ?
You plan to launch the missiles over Phillipines head ?? East Sea ( SCS ) is narrow one, you may need Phil coast to have the effect range of 1000 km ... to Vietnam coast. Or you plan to rent Subic naval base ?
While Vietnam airforce has ability to hunt your warships ...
China navy could outnumber only in the Oil Rig ( in effective range of all coastal defense system of Vietnam ). you never could outnumber in our coasts ...
I could sort out that Chinese airforce must be afraid of Vietnam airforce at this time in limit regional conflict
