One of China’s two new Jin-class SSBNs was photographed with two of its 12 missile tubes open when it visited Xiaopingdao Naval Base in March 2009.

在2009年3月，中国二艘新的晋级SSBN之一在泊留小平岛（Xiaopingdao）海军基地时它的12个导弹发射管中的2个开启时被卫星拍照。

The Jins are being readied to carry the JL-2, a single-warhead regional sea-launched ballistic missile that was most recently test-launched in May 2008. The class may become operational soon and replace the old Xia from 1982.

这艘晋级正在准备携带JL-2，一种单一弹头地区性潜射弹道导弹，最近在2008年5月试射。晋级可能很快成为可操作并且代替1982年服的夏级。

Xiaopingdao Naval Base, which is where I identified the Jin-class for the first time in 2007, serves as an outfitting and testing facility for new submarines and used to be the homeport of the single Golf-class diesel submarine China used for many years as a test launch platform for its first ballistic missile.

小平岛海军基地，我在2007年第一次识别晋级的地方，视为一个用于新的潜艇舾装和测试设施，过去一直是单独一膄“高尔夫”级柴电潜艇的母港，中国在许多年以前用于测试中国第一种潜射弹道导弹的发射平台。

Two or three Jin-class SSBN have been under construction, and it remains to be seen if China will build up to five as projected by U.S. intelligence. China’s nuclear submarines appear to be the noisiest nuclear submarines in the world and will probably be highly vulnerable at sea.

二或三艘晋级SSBN正在建造中，但仍有待观察，如果中国如同美国情报部门估计可能将最多建造5艘。中国的核潜艇似乎是世界上最嘈杂的核潜艇而且或许在海上非常脆弱。

The U.S. Office of Naval Intelligence described in August 2009 that two of China’s SSBNs (probably one Jin and the Xia) were based at the Northern Fleet Base in Jianggezhuang, and the third boat (probably the second Jin) at the Southern Fleet Base on Hainan Island. I identified the Jin at Hainan in February 2008.

美国海军情报办公室在2009年8月描述中国的SSBN中的二艘（或许一艘晋级和一艘夏级）部署在北方舰队的姜各庄基地，第三艘（或许第二艘晋级）在南方舰队的海南岛基地部署。我在2008年2月在海南识别了晋级。

The Obama administration’s first version of The Military Power of the People’s Republic of China is expected within the next month or two.

奥巴马政府第一个版本《中国军事力量》报告预期在下个月或二个月内发表。
