Russia-Ukraine War and Semiconductor Leverage

Key Insight

The Russia-Ukraine War starkly illustrates how a country's position in the semiconductor supply chain directly shapes its capacity to wield military and economic power. Russia's domestic chip industry has significantly declined since the Cold War, lagging behind Silicon Valley and further decaying as most Russian customers shifted to outsourcing production, predominantly to TSMC. Consequently, only Russia's defense and space industries remained as significant buyers, insufficient to fund advanced domestic chipmaking. This weakness meant that even high-priority defense projects, such as Russia's GPS-equivalent satellites, faced crippling delays due to difficulties in sourcing necessary semiconductors.

Russia's profound dependence on foreign semiconductor technology is evident in its military operations. Drones shot down over Ukraine have been found to contain foreign microelectronics, and the Russian military continues to rely extensively on non-precision-guided munitions; a prior analysis of its Syrian campaign found up to 95% of munitions were unguided. Furthermore, Russia experienced critical shortages of guided cruise missiles within weeks of invading Ukraine, a deficiency partly attributable to the dire state of its semiconductor industry. In stark contrast, Ukraine has received substantial stockpiles of guided munitions from Western allies, such as Javelin anti-tank missiles, each of which relies on over 200 semiconductors for targeting.

Russia's reliance on external semiconductor technology has granted the United States and its allies significant leverage. Following the invasion, the U.S., in coordination with partners in Europe, Japan, South Korea, and Taiwan, implemented sweeping restrictions on the sale of specific types of chips across Russia's tech, defense, and telecoms sectors. Key chipmakers, from America's Intel to Taiwan's TSMC, have ceased supplying the Kremlin. This has caused severe disruptions in Russia's manufacturing sector, leading to a substantial portion of its auto production being shut down. Even in sensitive defense sectors, Russian factories are resorting to evasive measures, reportedly deploying chips intended for dishwashers into missile systems, highlighting Russia's considerably weaker chipmaking capabilities today compared to the Cold War era.
