Coordinates: <a href="http://www.fas.org/blog/ssp/images/Jin-class%20SSBN.kmz" target="_blank">38°49′4.40″N, 121°29′39.82″E</a>.A commercial satellite image appears to have captured China’s new nuclear ballistic missile submarine. The new class, known as the Jin-class or Type 094, is expected to replace the unsuccessful Xia-class (Type 092) of a single boat built in the early 1980s.The new submarine was photographed by the commercial Quickbird satellite in late 2006 and the image is freely available on the <a href="http://earth.google.com/" target="_blank">Google Earth web site</a>. A Comparison of SSBN DimensionsTwo satellite images are now available (see figure below) that clearly show two missile submarines with different dimensions. One image from 2005 shows what is believed to be the Xia-class (Type 092) SSBN in drydock at the Jianggezhuang Submarine Base approximately 14 miles east of Qingdao. The submarine is approximately 390 feet (120 meters) long of which the missile compartment makes up roughly 80 feet (25 meters). Twelve missile launch tubes are clearly visible.The second image from late 2006 shows what appears to be the new Jin-class (Type 094) SSBN moored at the Xiaopingdao Submarine Base south of Dalian, approximately 193 miles north of Qingdao. The Jin-class appears to be approximately 35 feet (10 meters) longer than the Xia-class SSBN, primarily due to an extended mid-section of approximately 115 feet (35 meters) that houses the missile launch tubes and part of the reactor compartment. Xia- and Jin-Class SSBN Comparison<img src="http://www.fas.org/blog/ssp/images/ssbncompare.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />These two commercial satellite images of the old Xia-class SSBN (top) and the new Jin-class SSBN show the different major compartments. The Jin-class appears to be approximately 35 feet (10 meters) longer with an extended missile compartment. Both images view the submarines from a “eye-altitude” of approximately 500 feet (152 meters).The extended missile compartment of the Jin-class seems seems intended to accommodate the Julang-2 sea-launched ballistic missile, which is larger than the Julang-1 deployed on the Xia-class. Part of the extension may also be related to the size of the reactor compartment. The U.S. Office of Naval Intelligence estimated in 2004 that the Jin-class, like the Xia-class, will have 12 missiles launch tubes (see figure below). Other non-governmental sources frequently claim the submarine will have 16 tubes. The satellite image is not of high enough resolution to show the hatches to the missile launch tubes. Estimated Jin-Class SSBN Layout<img src="http://www.fas.org/blog/ssp/images/ssbnoni.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />The U.S. Office of Naval Intelligence estimated in 2004 (bottom) that the Jin-class SSBN would have 12 missiles.The U.S. Office of Naval Intelligence <a href="http://www.fas.org/nuke/guide/china/ONI2006.pdf" target="_blank">estimated</a> in December 2006 that China might build five Jin-class SSBNs. The estimate has been widely cited by non-governmental institutes and some news media as a fact, but the Pentagon’s <a href="http://www.fas.org/nuke/guide/china/dod-2007.pdf" target="_blank">annual report</a> on China’s military forces from May 2007 did not repeat the estimate.Background: <a href="http://www.nukestrat.com/china/chinareport.htm" target="_blank">Chinese Nuclear Forces and US Nuclear War Planning</a> | <a href="http://www.fas.org/blog/ssp/2007/05/pentagon_publishes_annual_chin_1.php" target="_blank">Pentagon Report Ignores Five SSBN Projection</a>                   In what will be a significant challenge to US Navy dominance and to countries ringing the South China Sea, one photograph shows China’s latest 094 nuclear submarine at the base just a few hundred miles from its neighbours.  <a href="http://www.telegraph.co.uk/news/worldnews/asia/northkorea/5155821/North-Korea-expels-UN-nuclear-inspectors.html" target="_blank">http://www.telegraph.co.uk/news/worldnews/asia/northkorea/5155821/North-Korea-expels-UN-nuclear-inspectors.html</a> Other images show numerous warships moored to long jettys and a network of underground tunnels at the Sanya base on the southern tip of Hainan island. Of even greater concern to the Pentagon are massive tunnel entrances, estimated to be 60ft high, built into hillsides around the base. Sources fear they could lead to caverns capable of hiding up to 20 nuclear submarines from spy satellites. The US Department of Defence has estimated that China will have five 094 nuclear submarines operational by 2010 with each capable of carrying 12 JL-2 nuclear missiles. The images were obtained by Janes Intelligence Review after the periodical was given access to imagery from the commercial satellite company DigitalGlobe. Analysts for the respected military magazine suggest that the base could be used for "expeditionary as well as defensive operations" and would allow the submarines to "break out to launch locations closer to the US". It would now be "difficult to ignore" that China was building a major naval base where it could house its nuclear forces and increase it "strategic capability considerably further afield". The development so close to the sea lanes vital to Asian economies "can only cause concern far beyond these straits". Military analysts believe that China’s substantial build up of its forces is gaining pace put has remained hidden from the world in the build-up to the Olympics. China has diverted much of its resources from the huge Peoples Liberation Army to the navy, air force and missile development. An old Russian aircraft carrier, bought by Beijing for "leisure activities" has been picked over by naval architects who hope to "reverse engineer" the ship. Within the next five to 10 years the People's Liberation Navy is expected to build up to six carriers which will also coincide with the Royal Navy’s construction of two major carriers. The location of the base off Hainan will also give the submarines access to very deep water exceeding 5,000 metres within a few miles, making them even harder to detect.</blockquote>
