According to Dmitry Shugaev, the head of Russia’s Federal Service for Military-Technical Cooperation (FSMTC), Russia may export its most advanced S-500 Prometheus air-defense weaponry to China and India after its own Armed Forces receive their allocations of the systems. Shugaev said, “When the [Russian] Armed Forces contracts are fulfilled, it will then be possible to supply the system for export. We consider India, as well as China and all those states with whom we have long-standing partnerships and stable relationships, as future owners of this latest system” (Radio Sputnik, November 2). Such a development would shift Eurasia’s military balance of power away from the United States and Europe. If exported, the S-500s would not only defend the Russian Federation but cover most of Eurasia with a next-generation anti-aircraft missile-defense shield specifically designed to counter US and North Atlantic Treaty Organization (NATO) aerial capabilities, including fighters, intercontinental ballistic missiles (ICBMs), hypersonics as well as low-Earth-orbit satellites.
