Balkhash Radar Station (also described as Sary Shagan radar node and Balkhash-9) is the site of two generations of Soviet and Russian early warning radars. It is located on the west coast of Lake Balkhash near Sary Shagan test site in Kazakhstan. Although it is used for monitoring satellites in low Earth orbit it is mainly a key part of the Russian system of warning against missile attack. It provides coverage of western and central China, India, Pakistan and submarine missile launches in the Bay of Bengal. There have been six radars at this site, although only one is operational in 2012, and it is run by the Russian Aerospace Defence Forces.
