On 22 June 2026, Ukraine struck the Voronezh Semiconductor Device Plant. Most of the coverage focused on what the plant feeds — components for the Kh-101 cruise missile, the Iskander-K, and the Pantsir air-defence system. The procurement record adds the part the strike footage cannot show: where the plant sits in the supply chain behind those weapons. Between 2014 and 2018, JSC VZPP-S (INN 3661033635) is the supplier of record on 298 Russian state contracts, worth roughly ₽1.19 billion, delivered to 58 separately sanctioned defence entities. It is an upstream node, one semiconductor plant that many production programmes draw on, rather than a single line building one system.
The customer set is the finding. Resolved one at a time, the 58 buyers span Russian air-defence, cruise- and ballistic-missile, naval, electronic-warfare and nuclear-weapons work. Against roughly 98,700 suppliers visible in the same contracting data, VZPP-S ranks 47th by number of sanctioned customers, placing it in the top 0.05%. The heaviest single dependency is the Central Design Bureau of Automatics (TsKBA), which alone accounts for 46 contracts worth about ₽260 million and builds passive anti-radar seeker heads. The convergence repeats on the product side: the Kh-101 and Iskander-K, the S-300V and Tor air-defence systems, the Oniks anti-ship missile and the nuclear-warhead complex all trace back through this one supplier.
What it shipped is consistent with that picture. By value the 298 deliveries are 39% microchips (₽466 million) and 18% transistors (₽208 million), with diodes, capacitors and bundled electronic components making up most of the rest — about 97% microelectronics overall. Two contracts carry explicit defence markers, one booked under the State Defence Order and one at military acceptance grade "5". The buyers place those parts in named systems: Mari Machine-Building (S-300V) and Izhevsk "Kupol" (Tor) on the air-defence side; Radiopribor in Kazan, which makes the SP-504 jammer carried on the Kh-101; VNII "Signal" for Pantsir-S1 and Iskander guidance; and five separate nuclear-weapons sites, including the Dukhov Institute (VNIIA) for warhead automatics and the design labs at Sarov (VNIIEF) and Snezhinsk (VNIITF).
The record stops in 2018, and the reason matters for how any analyst reads it. VZPP-S did not stop producing. On 28 December 2018, amendments to the law "On the State Defence Order" pulled defence contracting off the public register, and the effect shows up across the whole dataset: of roughly 1,400 sanctioned suppliers traceable in the records, about 80% make their last public contract by the end of 2018. General procurement stayed visible until the broader wartime blackout after February 2022. VZPP-S itself has been on the OFAC SDN list since 24 February 2023 under EO 14024 (electronics sector), with Japan and Australia following later that year. What the plant ships now is not in the open record, so the strike's effect depends on current output and on the physical damage, neither of which the procurement trail captures.
For compliance and sanctions analysts, the operational takeaway is to treat upstream component suppliers as multipliers rather than single endpoints. A microelectronics plant feeding 58 sanctioned buyers is not 58 separate exposure points; it is one chokepoint whose disruption, diversion, or replacement-sourcing touches air-defence, missile, naval and nuclear programmes at once. The same logic runs in reverse for screening: an entity that looks like an unremarkable regional electronics maker can be a higher-value node than any individual customer on a watchlist, which is exactly what the 47th-of-98,700 ranking captures. Component-level procurement mapping surfaces these hubs before a kinetic event forces the question, and the public 2014–2018 window remains usable for that even though it predates the classification cutoff. One correction worth carrying forward: two legally separate companies share the 119A campus address, VZPP-S and VZPP-Mikron. Early reporting named Mikron; the sanctioned entity and the hub by every measure above is VZPP-S. Same campus, different company.
