The Ukrainian military-industrial complex offers a number of options for modernization of the Soviet MLRS: modernization of the BM-21 Grad to the option Bastion-1 (2), and 9К54 Uragan to the option Bastion-3.
Modernization of the above complexes is carried out by installing the artillery unit (guides) removed from the BM-21 which were in storage or removed from the air force of Ukraine to a new KrAZ chassis.
The overhaul of the BM-21 part art is made by the Shepetovo Repair Plant GP. In the modernized version of the BM-21 Bastion -1 (2), the combat characteristics of the complex are improved by using new ammunition - which allows shooting to 40 km

The "Bastion-2" differs from the version (1) in the elongated chassis base, on which additional ammunition is placed. The same feature of this option is to equip the combat vehicle with two MANPADS.
In this variant, new ammunition is also used, allowing to fire up to 40km.
Option "Bastion-3" is an installation art.part of the MLRS "Uragan", mounted on the Kraz chassis. The replacement of the chassis was caused by the presence in Ukraine of its own chassis for this car - Kraz, the MAZ chassis (on which the Uragan complex was mounted) in Ukraine is not produced, but is only being repaired.
