Astros II (Artillery SaTuration ROcket System) is a self-propelled multiple rocket launcher produced in Brazil by the Avibras company. It features modular design and employs rockets with calibers ranging from 127 to 450 mm (5–17.72 inches). It was developed on the basis of a Tectran VBT-2028 6×6 all-terrain vehicle for enhanced mobility based on Mercedes-Benz 2028 truck chassis^[3] while later versions use Tatra 815-7 chassis.
