Now they are refueling and replenishment stations, you think China will just stop there? What makes you think Gwadar and Djibouti will not host aircrafts? An IOR fleet will be established first in Gwadar and Djibouti roughly matching Indian Navy, 10 destroyers and a dozen submarines will do, China can finish production in 5 years easy. Then HQ-10 missiles will be equipped in both bases and along Pakistani border. In event of war, China will send in reinforcements and attack Andaman, then the existing fleet in Gwadar will take action to tie down the Western flank, Pakistan will also assist. All of these is within Chinese capability. What you are seeing now is just the start.
Your only blockade is Andaman island and that is the first place to fall. You don't need 5 CBG to do that, one CBG will be adequate. We don't have to go near the Indian landmass, the purpose is just to flank India on both sides, when the Kyaupyu port is militarized. With this force in place, India cannot afford to disrupt Chinese trade lines. Do you know how many destroyers and Frigates and submarine China produced in 2016 alone? You are going against the world's second largest MIC and interms of naval production, I can say we are even bigger than the US. Hell, come to think of it, we are the world's largest naval builders.
Russians are observing Indian intimacy with US daddy ok, they will think twice about selling advanced weapons in the future. Apart from SU-35, aircraft engines and S-400, you think China is dependent on Russian arms? All project is to copy, steal and learn their technology. Whatever Russian ware you have now, we have the source codes too genius, but do you have access to indigenous Chinese weapons?
Again, you are just a US pawn, they will use you to fight us. Right, now go run to your daddy, cause you know you are toast if you face us alone.
