Ukraine's military intelligence has named the Russian companies that build the Su-35S fighter jet and singled out those no country has sanctioned, according to the Main Intelligence Directorate of Ukraine's Defense Ministry (HUR). The unsanctioned suppliers make parts as ordinary as wheels and fuel-system units, and one of them helped develop the aircraft. Kyiv wants sanctions efforts synchronized across every link of Russia's military-industrial complex.
The 22 firms no one has sanctioned
HUR identified 79 companies in the Su-35S production chain. Of those, 22 face no sanctions from any country restricting Russia over the war. The agency highlighted three. Rubin Aviation Corporation supplies the aircraft's braking and non-braking wheels. Gidroavtomatika builds the AU46-05 control units inside the fuel system. The Oktava research institute carried out design and development work on the Su-35S itself.
What the rest of the network builds
The 79 firms develop and produce the engines and fuel system, the control, communications, and guidance systems, the electronic warfare suite, and the main aviation missiles the jet carries into the war against Ukraine. HUR set the data out in the "Components in weapons" section of its War&Sanctions portal. The page carries a rotatable 3D model of the aircraft whose parts open onto the firms behind them, alongside directory listings and a profile for each company.
Ukraine mapped Russia’s Su-35 down to individual control units—and found 22 firms nobody has sanctioned
Three sanctions regimes, loosely aligned
The gaps HUR points to exist because the restrictions are not one list. The EU legislates in packages, the US and other G7 states maintain their own designations, and Ukraine issues sanctions by presidential decree, each covering a different set of firms. Kyiv has spent years asking partners to synchronize those lists, and its own designations often run ahead of them. A company can therefore supply a frontline fighter and still trade freely under most of them.
Previously, HUR ran the same exercise on the Su-34, where a third of the production network was still unsanctioned. The same pattern shows up above the component level, with Russia's largest arms conglomerate covered by EU measures while hundreds of its subsidiaries are not, and Western machine tools still sitting inside Russian missile plants.
