The Sverdlov Plant is not only russia's largest producer of explosive compounds used to fill all types of munitions — from artillery shells to ballistic missiles — but also the country's sole manufacturer of octogen (HMX) and hexogen (RDX)

The Sverdlov Plant can legitimately be classed as target No.1 and as one of the key pillars of russia’s defense industry. It is the country’s largest producer of explosive compounds and, by russian declarations, the only industrial-scale manufacturer of octogen and hexogen — internationally known as HMX and RDX, respectively.

Those compounds are the primary explosive filling for the vast majority of russian munitions: from artillery shells to aerial bombs and ballistic-missile warheads. Immediately adjacent to the plant, about 4 km away, lies the 53rd Arsenal, which fills aerial bombs — including heavy FAB-3000s — and artillery munitions.
