**OVERVIEW:** The Type 093A Shang II is a nuclear-powered attack submarine (SSN) operated by the People's Liberation Army Navy (PLAN). Entered service in 2015.

**DETAILS:**
The Type 093A Shang II represents a significant evolution of China's nuclear submarine technology, building upon the earlier Type 093 Shang class. Development was driven by a need to address perceived shortcomings in the PLAN's undersea warfare capabilities, particularly in anti-submarine warfare (ASW) and the ability to project power further from Chinese shores. The design incorporates improvements in acoustic quieting technology, aiming to reduce the submarine's signature and enhance its survivability in contested environments. While specific details of the design process remain closely guarded, it is believed that the Type 093A incorporates lessons learned from both domestic research and potentially, through analysis of foreign submarine designs. The elongated hull, compared to the original Type 093, likely contributes to improved hydrodynamic efficiency and internal volume, potentially accommodating enhanced sensor packages and crew facilities.

The primary roles of the Type 093A Shang II are anti-submarine warfare (ASW), anti-surface warfare (ASuW), and intelligence gathering. As an SSN, it provides the PLAN with a long-range, high-endurance platform capable of operating independently and supporting naval task forces in distant waters. Its ASW capabilities are crucial for countering potential threats from opposing submarines, particularly in the Pacific and Indian Oceans. The Type 093A also poses a significant threat to surface combatants, including aircraft carriers and surface action groups, due to its stealth and the torpedo armament. Intelligence gathering is another key function, enabled by its advanced sensor suite.

The Type 093A's sensor suite is comprehensive. The installation of the China Type 921-A "Golf Ball" radar likely provides surface search and navigation capabilities. The China SQC-207 fire control system is crucial for accurate targeting of torpedoes. The TSM 2233 Eledone sonar suite, incorporating the DSUV 2H towed array and DUUA 2D flank arrays, provides enhanced detection ranges and improved target classification. The China SJG-206A TASS (Towed Array Sonar System) further extends its passive detection range, improving its ability to detect and track quiet submarines at longer distances. The H/LQK-359A radar is likely used for electronic warfare support measures (ESM). The submarine also possesses optical and LLTV periscopes. The vessel's 533mm torpedo tubes allow the employment of a variety of torpedoes, including both domestically produced and potentially, acquired foreign designs, to engage both surface and subsurface targets. The Signal Ejector may be employed for the launching of countermeasures or communication buoys.
