A Chinese Submarine Was Lost and the Entire Crew Might Have Suffocated
Summary: In a tragic peacetime incident in 2003, a Chinese Type 035 submarine, designated as Submarine 361, suffered a catastrophic mechanical failure that resulted in the deaths of all 70 crew members aboard during a training exercise near the Neichangshan Islands.
-Submarine 361, a Type 035G vessel produced between 1990 and 1999, was considered obsolete by the early 2000s despite upgrades aimed at enhancing its capabilities.
-The exact cause of the accident remains unclear, with speculation centering around possible suffocation due to oxygen depletion or poisonous gas leakage from the submarine's diesel generator. The lack of transparency from Chinese officials leaves many questions unanswered, casting a shadow over the incident and the fate of its crew.
Mystery Surrounds the Deadly Incident of Chinese Submarine 361
In 2003, a Chinese Type 035 submarine suffered a mechanical failure that would lead to one of the country’s most severe peacetime military disasters. All 70 crew members on board the submarine were killed during a training exercise.
The vessel, identified as submarine 361, was recovered from Chinese territorial waters east of the Neichangshan Islands days later.
Introducing Submarine 361
Submarine 361 was developed as a Type 035G vessel, a sub-type produced between 1990 and 1999. Twelve Type 035G boats were designed to incorporate an array of capabilities including noise reduction and stronger weapons.
These aging vessels were considered obsolete by the early 2000s, and Chinese officials, according to some reports, referred to the upgraded variants as “new wine in an old bottle.”
The Accident
Right after the accident, a Chinese Foreign Ministry spokesperson said that the submarine was “training in our territorial waters east of the Changshan Mountains, all 70 officers and soldiers on board were killed due to mechanical failure,” and provided no further details.
The spokesperson only said that, “submarine 361 was a major loss for the People’s Navy. We express our deep condolences to all officers and soldiers of the submarine who were unfortunately killed in the execution of training tasks, and sincere condolences to the relatives of the killed officers and soldiers.”
What Really Happened? Suffocation Is Possible
Beijing is not known for its transparency, so a more detailed analysis of the submarine 361 mishap was never to be expected. However, one leading theory surrounding the event is that the submarine’s onboard diesel generator could have malfunctioned and used up all remaining oxygen.
If this is true, the submarine crew likely suffocated at their posts before even recognizing any danger.
Other experts have speculated that a poisonous gas, perhaps carbon monoxide, could have leaked from the ship’s diesel engines, also resulting in suffocation.
Without a thorough and transparent review of the tragic submarine 361 incident, we may never know why the vessel’s 70 crew members died.
