Russia has started an upgrade of the Neman-P radar located at the Sary-Shagan test site. The radar (see the map below) was designed in the late 1960s by one of the three competing missile defense projects (the other two being the A-35 and a project that eventually became A-135).

At the time, Neman, was promoted as a radar that could provide better target discrimination capability than its competitors. The pilot radar that was built in Sary-Shagan, Neman-P, apparently has been used in various tests of ballistic missile reentry vehicles launched from Kapustin Yar. It probably began operations in 1981 and has been used in this role ever since.
