On October 29, 2009, Russia conducted a test of the 53T6 interceptor of the A-135 Moscow missile defense system (also known as Gazelle). According to a press report, the test was fully successful, which would allow the Space Forces to "considerably" extend service life of the interceptors.
In the last several year, interceptor tests have been conducted annually to confirm their characteristics and extend service life. No test was reported in 2008. However, two tests were conducted in 2007, as part of the program of modernization of the A-135 system, which includes an upgrade of the Don-2N battle management radar.
