Part 3/7:
The 94th Arsenal is among the oldest military depots in Russia, with its origins tracing back to the early 20th century, and even further back to the establishment of gunpowder magazines in the early 1700s. This critical strategic location, away from urban centers due to the risk of explosive containment failures, has been documented since at least the 1800s. US intelligence monitored the site closely during the Cold War, employing sophisticated aerial surveillance methods, including U2 spy planes, to gather data about military readiness and stockpiles.
