Lack of transparency over military accidents haunts China

Beijing [China] May 18 : The Chinese government is not disposed to transparency regarding its military accidents and experts belive that Military commissioner and former president Jiang Zemin acknowledged the tragic incident on May 2, 2003 of Ming class 361 in which all the 70 crew members were found dead just to downplay SARS epidemic.
China has never been transparent regarding its military accidents. Any breakdown in crew discipline or mechanical reliability can turn a submarine into watery coffins.
High standards of maintenance, manufacturing, and crew training can avert lethal peacetime disasters--standards which are difficult for many nations to afford, but which the PLA Navy likely aspires to it as it continues to expand and professionalize its forces at an extraordinary rate,says Sebastien Roblin, writing for the National Interest.
According to The National Interest, the Chinese government is not disposed to transparency regarding its military accidents. For example, it does not release the results of its investigations into jet fighter crashes and it never publicly acknowledged earlier submarine accidents.
At the time, some commentators expressed surprise that Beijing acknowledged the incident at all, and speculated it was obliquely related to contemporaneous criticism of Beijing's attempts to downplay the SARS epidemic.
In the year 2003, of the month of April, the crew of a Chinese fishing boat noticed a strange sight--a periscope drifting listlessly above the surface of the water. The fishermen notified the People's Liberation Army Navy (PLAN) which promptly dispatched two vessels to investigate.
PLAN believed the contact to be an intruding submarine from South Korea or Japan. But when Chinese personnel finally recovered the apparent derelict they realized it was one of their own diesel-electric submarines, the Ming-class 361, as reported by the National Interest.
However, when they boarded on April 26, they found all seventy personnel slumped dead at their stations.
Military commissioner and former president Jiang Zemin acknowledged the tragic incident on May 2, 2003, in a statement honouring the sacrifice of Chinese sailors' lives and vaguely characterizing the cause as "mechanical failure."
A month later, an inquiry by his commission resulted in the dismissal of both the commander and commissar of the North Sea Fleet and the demotion or dismissal of six or eight more officers for "improper command and control." Jiang and President Hu Jintao later reportedly visited the recovered submarine and met with the families of the deceased.
The Type 035 Ming-class submarine was an outdated second-generation design evolved from the lineage of the Soviet Romeo-class, in turn, a Soviet development of the German Type XXI "Electric U-Boat" from World War II. The first two Type 035s were built in 1975 but remained easy to detect compared to contemporary American or Russian designs. Though China operated numerous diesel submarines, due to concerns over seaworthiness, they rarely ventured far beyond coastal waters in that era, reported by The national interest.
Nonetheless, Chinese shipyards continued to build updated Ming-class boats well into the 1990s. Submarine 361 was one of the later Type 035G Ming III models, which introduced the capability to engage opposing submerged submarines with guided torpedoes. Entering service in 1995, she and three sister ships numbered 359 through 362 formed the North Sea Fleet's 12th Submarine Brigade based in Liaoning province.
361 had been deployed on a naval exercise in the Bohai Sea, the Yellow Sea gulf east of Beijing and Tianjing. Unusually, a senior naval officer, Commodore Cheng Fuming was aboard. In its last ship's log on April 16, the submarine was practising silent running while off the Changshang island, heading back to a base in Weihai, Shandong Province.
Because it was maintaining radio silence, the PLAN didn't realize anything was amiss until ten days later. The method by which 361 was recovered after its presence was reported remains unclear. Several accounts imply the ship was submerged, but the fact that it was promptly towed back to a port implies that it had surfaced, as reported by The National Interest.
Sebastien Roblin citing The Hong Kong Sing Tao Daily, says, " Another theory is that leaks allowed seawater to mix with battery acid, forming deadly chlorine gas that poisoned the crew. The Hong Kong Sing Tao Daily claimed the submarine had embarked on a "dangerous" antisubmarine training, and that "human error" led it to nose-down uncontrollably, causing it to get stuck on the seafloor."
A conventional diesel-electric submarine uses an air-breathing diesel engine to charge up its batteries for underwater propulsion. This is usually done while surfaced--but a submarine attempting to remain undetected can also cruise submerged just below the surface and use a snorkel to sip air. The snorkel is designed to automatically seal up if the water level gets too high.
According to Wen Wei Po, 361 was running its diesel while snorkelling when high water caused the air intake valve to close--or the valve failed to open properly due to a malfunction. However, its diesel engine did not shut down as it should have in response.
