The head of Russia’s Roscosmos space agency said on Friday that the country has deployed an advanced intercontinental ballistic missile that President Vladimir Putin once said will make Russia’s enemies “think twice.”

“The Sarmat strategic missile system has entered active duty,” Roscosmos chief Yuri Borisov said. According to Sputnik News, “The RS-28 Sarmat is Russia’s next-generation intercontinental ballistic missile (ICBM) that is set to become the backbone of the country’s silo-based strategic deterrent. With its impressive range and destructive power, the Sarmat is considered one of the deadliest nuclear missiles in the world.Based on experts’ estimates, the RS-28 Sarmat is capable of delivering a MIRVed warhead weighing up to 10 tonnes to any location worldwide, both over the North and South Poles,” added Borisov.
