   The ASTROS II (Artillery SaTuration ROcket System) was developed by AVIBRAS of Brazil. This company was developing multiple launch rocket systems since the early 1960s. The ASTROS II entered service with Brazilian Army in 1983. This rocket system has been exported to Bahrain, Malaysia, Qatar and Saudi Arabia. It license-produced in Iraq as the Sajil-60.

   The ASTROS II has a modular design of launching containers. It can be fitted with four standard containers with rockets. The ASTROS II fires four types of rockets. These include SS-30 127 mm rockets, SS-40 180 mm rockets, SS-60 300 mm rockets and SS-80 300 mm extended-range rockets. Depending on the caliber a single container holds eight, four or one rocket. Maximum range of fire is 30, 35, 60 and 90 km respectively. All of these rockets are fitted with High Explosive Fragmentation (HE-FRAG) warheads. The SS-40, SS-60 and SS-80 rockets are also available with cluster warheads. Some sources claim that the ASTROS II also fires mine-dispensing and incendiary warheads.

   All launching procedures are made from the inside of the launcher vehicle.

   Secondary armament consists of 12.7 mm machine gun, mounted on top of the cab roof. It is also fitted with smoke grenade dischargers.

   The ASTROS II uses chassis of Tectran series high mobility vehicle. It is a modified military version of Mercedes-Benz 6x6 high mobility truck. Vehicle has a lightly armored cab, providing protection against small arms fire and artillery shell splinters. It is powered by a Mercedes-Benz OM422 diesel engine, developing 280 horsepower.

   The ASTROS II is supported by an associated reloading vehicle, fitted with a crane. Reloading vehicle also carries two sets of reloads.

   A battery usually consists of 6-8 launcher vehicles, the same number of reloading vehicles, command and control vehicle, battery fire control vehicle, mobile workshop and mobile meteorological station.

   A couple of years ago it was reported that AVIBRAS was developing a new generation ASTROS III multiple launch rocket system, which will be capable of firing cruise missiles with a range of 300 km. The launcher vehicle had an 8x8 configuration and could carry heavier rockets. It was planned that the ASTROS III will be capable of launching cruise missiles with a range of 300 km. It seems that the 8x8 launcher vehicle never passed a prototype stage, though other components of this program were incorporated into improved ASTROS II systems.

   In 2014 a first improved ASTROS II Mk.6 was delivered. This system is also referred as ASTROS-2020. The launcher vehicle is capable of firing new AV-TM 300 cruise missiles with a range of 300 km and AV-SS-G40 guided rockets. It was planned that Brazilian Army will operate three batteries of this version. Deliveries were planned to be completed in 2018.
