Ukraine has meticulously mapped the Russian Su-35 fighter jet, not just identifying its components but pinpointing the specific firms providing them. Their investigation extends down to individual control units within the aircraft. The analysis revealed 22 companies supplying vital parts – engines, guidance systems, jamming equipment, and air-to-air missiles – that have thus far avoided international sanctions. This detailed mapping aims to pressure the West to broaden sanctions targeting Russia’s military-industrial complex. The findings suggest Russia is relying on a network of previously unsanctioned suppliers to maintain its arms production. Ukraine hopes this information will disrupt Russia’s ability to build and repair advanced weaponry, hindering their war efforts. The investigation highlights vulnerabilities in the international sanctions regime and the potential for circumvention.
