The captain of the Chinese PLA Navy submarine '093-417' is understood to be among the deceased, as were 21 other officers.

The UK report into the fatal mission reads:

Our understanding is death caused by hypoxia due to a system fault on the submarine. The submarine hit a chain and anchor obstacle used by the Chinese Navy to trap US and allied submarines.

This resulted in systems failures that took six hours to repair and surface the vessel. The onboard oxygen system poisoned the crew after a catastrophic failure.

Beijing has dismissed open source speculation about the incident as 'completely false' while Taiwan has also denied internet reports.
