6. Shanghai defenses / 上海防空

Until the S-300 PMU-2s are deployed Shanghai is probably the best defended city in China.

部署了S-300 PMU-2防空导弹部队的上海可能是中国对空防御最好的城市。

The defenses were overhauled in about 2005:

于2005年被发现的防空阵地：

Shanghai also has a belt of AAA sites on the north side. Curiously these do not appear elsewhere.(Note: AAA sites in China are *** hard to find. These locations come courtesy of Top81.net. There could be many more sites maybe all over Shanghai buy I can’t find any others).

在上海的北边还有一条由防空炮组成的带状防区。有意思的是这样的布置从来没有在其它地方出现过。（注：中国的防空炮阵地实在是太***难找了。图中这些阵地位置的确定要感谢TOP81.NET网站，这样的阵地在上海应该还有许多，但我实在是找不到其它的阵地了。
