Artillery: Doing The Math
July 28, 2022: Since the Russian invasion of Ukraine in February the Ukrainians have had special teams investigating sites where Russian guided missiles landed, seeking fragments of the guidance system to determine which components were imported from the West. Russia has found they could not mass-produce many Western electronic items and that it was cheaper and easier to import them from the West (which includes South Korea, Japan and sometimes even Taiwan). The 2022 economic sanctions imposed on Russia halted export of electronic components used in missiles and guided rockets.
It was noted that many Russian manufacturers did not stockpile these components but used the more efficient and less expensive “just in time” system that had needed components delivered days before they would be needed for production items. The Russian economy could not afford to maintain stockpiles of these expensive components, something that became evident after 2014, when the first and milder round of economic sanctions were imposed on Russia. After 2014 Russia had to halt production of some systems because they could no longer get key components from foreign suppliers. The 2022 sanctions took note of this and immediately halted shipment of a wide range of electronic components to Russia. As expected, a lot of Russian manufacturing operations soon halted. Russia sought to smuggle in key components via China but that did not solve the problem. This use of China as a middleman for high-tech smuggling was a known problem and China was warned that they would be added to the sanctions list if they assisted the Russians. Evidence of such smuggling could be detected via examination of the missile fragments.
