They've already ordered and launched quite a large number of modern ships in the mid to late 2010s.
Now they are:
- continuing a moderate pace of ship procurement for the surface fleet
.....
At one time China was literally building (2 Frigates, 4 Destroyers, 2 Cruisers, and 1 Landing Helicopter Dock)
on average per year.
Nobody was expecting these numbers to go on indefinitely.
The Last decade was the decade of surface combatants and amphibious assault ships.
Going forward, I expect the number of surface combatants and LHD's being launched to slow down a bit as some of the (money, material, and manpower) gets redirected to building submarines and carriers.
The next decade will be the decade of nuclear powered submarines and aircraft carriers......it should be exciting!
And what comes after the year 2035?
China will have all the equipment / weapons necessary for self defense. The next step will be to develop the capacity to project that power abroad long distance. I expect to see a lot of oversea military bases, diplomatic ties, and logistic supply lines being created.....but that's maybe getting ahead of ourselves here.
