Jianggezhuang is a Chinese naval base approximately 15 miles (24 km) east of Qingdao on the Yellow Sea. The base spans a bay 1.2 miles (1.9 km) across, with the main facilities located in the eastern portion of the bay. There are 6 piers, a dry dock, various service facilities and an underground submarine tunnel.The base hosts China's Type 092-class ballistic missile submarine and Type 091-class nuclear attack submarines.

Han 403 Long March 3. Type 091/09I, 5,500t dived. As of 2008 the first generation Chinese SSN (401 to 405). The leading boats suffered radiation problems which were supposed to be solved after extensive refits. Improvements have been made on the remaining boats including better torpedoes and capability to launch YJ-82 AShMs from the torpedo tubes. A new black tile coating may have been applied to the hull in addition to new rectangular shaped venting holes. A new cylindrical bow sonar (H/SQG-262B) was also installed, as well as a 7-blade skew propeller to reduce noise. Type 091G may have new flank sonar arrays installed as well. One Han class SSN was spotted in May 2005 at a newly commissioned nuclear sub base in Hainan Island north of the South China Sea. This was the first time that an SSN was deployed in the South China Sea region, reflecting its strategic importance to China.

Xia 406 Long March 6. Type 092G/09II, 6,500t dived. This modern SSN included a new black paint, a new bow mounted sonar (H/SQG-262B), redesigned casing housing longer missile launch tubes, plus upgraded combat control systems for launching new SLBMs. Initially armed with 12 JL-1 (CSS-N-3) SLBMs (inertial guidance to 1,700km with a single 1.25MT nuclear warhead, improved version has a range of 2,500km), it is believed to carry the new JL-2 SLBMs (CSS-NX-4, with 3 or 4 MIRV at 90kT each, range 8,000km). For years Xia 406 has been PLAN's sole nuclear deterrence force. The submarine has become a valuable testbed for PLAN to shape its tactics and strategies for modern SSBN warfare since the first successful test fire of JL-1 SLBM in 1988. It was reported that a JL-2 SLBM was successfully test-fired from 406 on June 16, 2005.
