Russian tactical missile system Iskander uses now terminal guidance system photos target 1511113.

The upgraded missile designated 9M723 for the Iskander system was tested last week by an artillery use and research center, reports Izvestia newspaper citing a source in the General Staff.

“The guided missile is homed ‘by photo’, that is compares the actual view to a pre-loaded digital image of the target,” the source explained.

The technology is similar to Pentagon’s Digital Scene-Mapping Area Correlator (DSMAC). In the case of the Iskander it helped improve the missile’s accuracy twofold. The versions currently deployed have Circular Error Probable (CEP) of 10 meters, while for the new missile it was lowered to merely 5 meters.

The improved precision makes the Iskander more efficient against highly fortified underground targets, the source says.

Iskander is a mobile theater-level ballistic missile system. It is a designated replacement for the older Tochka missiles, which had been deployed since 1970s. The first brigade armed with the missiles was formed in October this year. A total of 120 Iskander launchers are to be deployed by Russia by 2020.

The missile can be armed with different loads, including tactical nuclear warheads. Its estimated maximum range is 280 kilometers. An Iskander launcher can also potentially fire cruise missiles.
