had helped Angola to defeat the UNITA. New generation The next step is an ambitious program, the Astros 2020 (Mk6), based on a 6×6 wheeled chassis. Being a new concept, it will require an estimated investment of R$1.2 billion, of which about US$210 million will be invested solely in development. It will be integrated with the cruise missile AVMT-300 with 300-km range during the stage of testing and certification. It is said that the venture will, for example, enable the Army to integrate the Astros with defense anti-aircraft guns, paving the way for the utilization of common platforms, trucks, parts of electronic sensors and command vehicles. The new MK6 system will use Tatra Trucks’ T815-790R39 6×6 and T815-7A0R59 4×4 trucks instead of the original Mercedes-Benz 2028A 6x6 truck. ASTROS 2020 offers several basic improvements including an improved armored cabin, modern digital communications and navigation systems, and a new tracking radar that replaces the AV-UCF's Contraves Fieldguard system. The new tracking radar used by MK6 AV-UCF was latter revealed to be the Fieldguard 3 Military Measurement System from Rheinmetall Air Defence. The Astros 2020 will also be equipped with a 180 mm GPS-guided rocket called the SS-AV-40G with a range of and SS-150 newly developed rockets with a claimed maximum range of 150 km. Four of them are carried. 36 Astros 2020 systems are to be acquired.
