If the F-35 fell into the sea and if a PLAN asset(s) was tagging along the carrier, what happens then?
Would the PLAN let the USN to salvage the aircraft uninterrupted?
The USN as well as the PLAN are racing to get the appropriate type of equipment to recover, due to the location, the PLAN would necessarily have an advantage, but that will depend a lot. It becomes a benevolent point that China has a direct imagination of where the F-35C entered the waters of the South China Sea, making its advanced stealth technology an attractive target for China to launch its own rescue operation. While both have the proper equipment like deep-diving submersibles that pull the wreckage from the ocean floor, both will want to get hold of the F-35C wreckage and that could lead to the inevitable rush.
Just as a curiosity, I read that Carl Vinson is already in Singapore, although I haven't had time to confirm this news yet.
