ASTROS II Mk3M

The ASTROS II (Artillery Saturation Rocket System) is a Brazilian-developed multiple launch rocket system (MLRS) designed to provide heavy fire support. The Mk3M is an upgraded variant, featuring improved fire control, navigation, and communication systems, capable of launching a wide range of rockets and tactical missiles.

Developed by Avibras in the early 1980s, the ASTROS II was initially designed to fulfill Iraqi operational requirements for a highly mobile, long-range saturation bombardment system during the Iran-Iraq War. The system officially entered service with the Brazilian Army in 1983, with the Mk3M modernization standard later introduced to upgrade existing inventories with digital fire control and GPS-assisted navigation. It saw extensive combat deployment with Iraqi forces during the Iran-Iraq War and was later utilized by Saudi Arabia during the 1991 Gulf War and subsequent operations in Yemen. Today, the ASTROS II family remains the cornerstone of Brazil's strategic artillery capability and continues to be exported globally, serving as the developmental foundation for the AV-TM 300 tactical cruise missile.
