Nobody has fought a current-tech Naval war since 1945. The situation is ripe for surprises in all directions. Weapons systems and sensors and tactics and platforms will be found to be useless, inadequate, or decisive wonder weapons. No telling what they will be.
My current expectation is that Chinese ship survivability is poor vs US long range attack from USN and USAF systems, and ditto for their submarines. And this is without risking carrier groups within the danger zone of Chinese missile attack.
Strategically the Chinese Navy is a long way from being able to protect their foreign trade from a USN “distant blockade”, a la the Royal Navy vs Germany in WWI and WWII.
But we may find out.
I have this image of drone swarms just overwhelming sensors on our weapons. Flying - exploding spray cans of paint would really mess up optics. Dangling wires like Portugese-man-of-war drones could short out power lines.
