The latest production of the Fajr-5 is installed on a new 6×6 forward control chassis and the platform is now integrated into a complete weapon system rather than an individual launcher. To provide a more stable firing platform four hydraulically operated stabilizers are lowered to the ground before firing. The new chassis has improved cross-country mobility and the forward control fully enclosed cab provides space for the driver and two passengers. Another fully enclosed cabin to the immediate rear of the cab houses the remainder of the crew. The new Mercedes-Benz chassis is similar to that manufactured in China, which is used as the basis for the Norinco (China North Industries Corporation) 122 mm (40-round) Type 90 ARS. While the primary role of this artillery rocket system is the engagement of land targets, AIO says that a radar can be added to give the system the capability to track and engage naval targets. The Fajr-5 missile, which is launched from a mobile platform, reportedly has a range of 75 kilometers (50 mi). Also a two-stage version of the rocket is reported to be produced with a length of 9 m and range of 190 km. But this variant is launched from TELs similar to Zelzal missiles which only has the capacity for a single rocket.
In February 2017, Iran revealed a guided version of the Fajr-5, similar to the Chinese SY300. It has a firing accuracy of 250 m when using INS and 50 m using GNSS, with range from 40-130 km (25-81 mi).
The first Fajr-5 were created when China exported WS-1 MLRS to Iran in the late 1980s/early 1990s. They were then subsequently created and produced by Iran's Aerospace Industries Organization. In May 2006, Iran's Aerospace Industries Organization (AIO) has developed an upgraded version of the well-established Fajr-5 333 mm (4-round) unguided surface-to-surface artillery rocket system (ARS).
