Okay, I will start making the BM-30 Smerch first as I don’t think it will be so much of a hassle as I have some of the parts made from other Russin models.
The BM-30 Smerch (Russian: Смерч, “tornado”, “whirlwind”), 9K58 Smerch, or 9A52-2 Smerch-M is a heavy multiple rocket launcher. The system is intended to defeat personnel, armored, and soft targets in concentration areas, artillery batteries, command posts, and ammunition depots. It was designed in the early 1980s and entered service in the Soviet Army in 1989. When first observed by the West in 1983, it received the code MRL 280mm M1983. It continues in use by Russia; a program to replace it with the 9A52-4 Tornado began in 2018.
