The Type 093 (NATO reporting name: Shang, Chinese designation: 09-III) is a nuclear powered attack submarine class deployed by the Chinese People's Liberation Army Navy. These boats are expected to replace the older Type 091 (NATO: Han class) SSNs currently in service. The Type 093 will be armed with various torpedoes and anti-ship missiles. The lead boat in this class was launched in 2002. It is thought to have a seven-blade asymmetric propeller. Construction of the Type 093 submarines is being conducted at the Bohai Shipyard in Huludao. Six to eight boats are expected to be built.
