"I'm sure the US is spying on the Chinese in the region, and this sort of drone is probably involved."
Erm, spying, not so much. Studying thermoclines and salinity changes, etc, yeah.
All the better to hide submarines.
I can't for the life of me figure out *why* the PRC would mind US submarines near their waters. Why, the Russians loved them north of the Kola Peninsula for all of those decades.
