Russia’s new Sarmat ICBM, which is capable of overcoming missile defense systems, has completed tests and is a “breakthrough” for the country’s missile program, President Vladimir Putin announced on March 1. Sputnik tries to find out what this missile is all about. The Sarmat heavy intercontinental ballistic missile, which Russia has been testing since last year, will replace the aging but reliable Soviet-era R-36M2 Voyevoda (SS-18 Satan) ICBMs.
