Ukraine continued its campaign targeting Russian infrastructure, reportedly striking refineries and depot facilities. Simultaneously, Ukrainian investigators revealed a network of 22 companies allegedly supplying key components for Russian military hardware. The investigation focused on a downed Su-35 fighter jet, tracing parts back to unsanctioned suppliers of engines, guidance systems, and missiles. This discovery highlights potential vulnerabilities in Russia’s defense industry and exposes possible avenues for further sanctions. The findings suggest Russia is relying on a complex, and potentially illicit, supply chain to maintain its military capabilities. The investigation raises questions about the enforcement of existing sanctions and the effectiveness of international efforts to curb Russia’s access to vital technology. This dual approach – direct strikes and supply chain disruption – signals a broadening Ukrainian strategy.
