Type 093 submarine
The Type 093 submarine (NATO reporting name: Shang class) is a class of nuclear-powered attack submarines constructed by the People's Republic of China for the People's Liberation Army Navy. Development
GlobalSecurity.org reports that development of the Type 093 began in the early 1980s. However, Admiral Liu Huaqing wrote in his memoirs that development began in 1994 following President Jiang Zemin's continued support for nuclear submarine development after the launch of the final Type 091 in 1990. Erickson and Goldstein suggest that the Yinhe incident in 1993, and continued tensions with Taiwan, also drove Jiang Zemin's support of the program. Russian experts aided the design. The first Type 093 was laid down in 1994 and commissioned in 2006. The second was laid down in 2000 and commissioned in 2007. The first Type 093A was laid down in 2009 and was commissioned in 2015. Unsubstantiated rumors from Taiwan sources 
On August 21, 2023, unsubstantiated rumors emerged on social media claiming that a Type 093 had suffered severe damage in an incident in the vicinity of the Taiwan Strait. A spokesperson for Taiwan's Ministry of National Defense said that the nation's intelligence and surveillance systems had not detected evidence of such a crash, while H. I. Sutton wrote that he had "not seen any convincing evidence to support" the rumors, which claimed the sub had suffered a fatal incident which killed all aboard. On August 31, Chinese PLA colonel Wu Qian issued a denial on behalf of the Ministry of National Defense, saying "reports claiming that a Chinese Type 093 nuclear-powered submarine had an accident in the Taiwan Straits are completely false."

Initial design. In the early 2000s, Chinese sources reported that the Type 093's noise level was on par with the improved Los Angeles-class submarines, and with Project 971 (NATO reporting name Akula) at 110 decibels. In 2009, USN ONI listed the Type 093 as being noisier than Project 671RTM (NATO reporting name Victor III) which entered service in 1979. Two built. NATO reporting name Shang I. Type 093A
