Digital Combat Simulator World (DCS World) is a free-to-play digital battlefield game, focusing on simulation of military aircraft. It includes the FREE Su-25T and TF-51D aircraft and it is extensible through additional DCS modules as well as user-made add-ons and mods.
DCS World includes a vast mission area of the Caucasus region that encompasses much of Georgia - the location of the Russian invasion of Georgia in 2008.
The NS 430 GPS navigation system is an optional add-on module for DCS World aircraft. Starting with DCS: Mi-8MTV2, the NS 430 provides powerful, yet intuitive, navigation and radio communications options to supplement the navigation and radio systems already integrated into our aircraft. The NS 430 is particularly useful for older aircraft with less sophisticated navigation and communication systems.
