History

The majority of the facilities were built in the 1970s and 1980s during the Soviet Union. The arsenal was listed among the GRAU's installations during the 1980s.
In 2013, it was decided to modernize the arsenal with fortified bunkers built to modern standards. However, nearly half of the 1.3 billion ruble budget was misappropriated by contractors. Work continued until 2021. Satellite images show that more than half of the buildings, including all those along the railway, were not covered with any layer of earth, but only protected by revetments. Many revetments appear to have been built only on one side of the buildings, not around them. Photos show that ammunition crates were stored in the open air.
In June 2002, four people were killed when ammunition exploded during unloading operations.
On June 28, 2022, the cell "BOAK-Vladimir" published a press release claiming sabotage action on the arsenal's railway. The rails were damaged. BOAK's press release stated, "Every stopped train helps to get rid of missiles and rockets, which could hit peaceful Ukrainian cities!"
