A total of 20 boats were built, of which 17 are left, and most serve in the North Sea Fleet. No. 361 serving the East Sea Fleet was the thirteenth and was built in 1995 making it one of the newest in the fleet.

Incident

According to the official Chinese news agency, Xinhua, the submarine was taking part in exercises east of Neichangshan islands in the Bo Hai Sea (渤海) of Northeastern China. http://news.xinhuanet.com/english/2003-07/02/content_936853.htm. The captain of the boat was (Naval) Senior Colonel (equivalent of a commodore) Cheng Fuming (程福明). Among the 70-member crew, 13 of them were not part of the original crew, but instead, trainees and cadres from the naval academy.

On April 16, 2003, all 70 crew members of the submarine were killed when the diesel engine failed to shut down when the boat submerged and used up all the oxygen in the boat.

According to Xinhua on May 2, 2003, the crippled boat was discovered by Chinese fishermen on April 25, 2003, when they noticed the periscope sticking out. The submarine was then towed initially to Yulin on Hainan Island, and later towed back to the northeast seaport of Dalian

. The submarine was drifting for ten days because it was on a silent, no-contact drill.

Mystery

A number of issues arose with this incident:
  • Michael McGinty, an expert on the Chinese navy at the Royal United Services Institute
    Royal United Services Institute
    The Royal United Services Institute for Defence and Security Studies , officially still known by its old name, the Royal United Services Institution, is a British defence and security think tank. It was founded in 1831 by The Duke of Wellington.RUSI describes itself asIt won Prospect Magazine's...

     for Defence Studies in London and a former British submarinerhttp://www.dcfp.navy.mil/mc/articles/other/MingSub.htm, said "The accident likely happened while the submarine was on the surface. If the accident happened when the boat was under water, it was less likely China could have recovered it." This contradicts the official version that the submarine was submerged.

  • One leading theory for the accident is called engine run-on casualty. This happens when the diesel engines are still running while the submarine is submerged, instead of switching to electric motors. This results in the diesels sucking oxygen out of the inside of the submarine, suffocating the crew. But this is dismissed because the original Russian design of this submarine has a device that cuts off diesel fuel supply to the engines if it detects a drop in barometric pressure inside the hull.

  • Another theory is that seawater seeped into the batteries creating a toxic environment via deadly chlorine

    Chlorine is the chemical element with atomic number 17 and symbol Cl. It is the second lightest halogen, found in the periodic table in group 17. The element forms diatomic molecules under standard conditions, called dichlorine...

     gas that could kill an entire crew while on the surface. Again, chlorine gas does not kill instantly. Chlorine gas also has a very distinctive smell.

  • Other military commentators also pointed out that the sea water outside of the Liaodong Peninsula was only one to two hundred meters deep, which was considered shallow for a submarine.

  • Also, all submarines have multiple escape hatches. So the inability of any of the crew to escape is also considered puzzling.

  • The Chairman was shown visiting the submarine at Dalian during the first week of May. The submarine was very clean during the visit, which made observers wonder if it were the original.

  • The usual complement of a Ming-class submarine is 9 officers and 46 crew. So the existence of 15 additional personnel onboard is puzzling, but may be related to the exercises. It has been speculated that the submarine was testing an AIP

     system when the accident occurred.

  • When the flap valve, fitted to the snorkel which sucks in the oxygen, shuts in response to water being sucked into the snorkel it causes a temporary pressure drop in the submarine. This change in pressure is quite noticeable, for example your ears will pop and you might feel that your head is swelling. This generally can happen for short periods of time. However, if the diesel engines were running the crew would have known this was happening and should have been able to don EBS (emergency breathing system) if fitted. This is the first emergency procedure taught to new recruits to a submarine.
