On September 20, Russia successfully test fired a SS-29 Yars intercontinental ballistic missile on the final day of the Zapad 2017 military exercise. As part of the exercise, Russian missile crews practiced relocating the missile, testing its mobile variant rather than the silo-based variant tested on September 12. The missile was launched from Plesetsk launch site in northwestern Russia, travelling approximately 6,000 km before its multiple warhead payload hit targets at the Kura testing range in far eastern Kamchatka Peninsula. The purpose of these tests was to “reaffirm the reliability” ICBM.
