According to a Russian defense industry source, the SS-X-30 Sarmat intercontinental ballistic missile, frequently referred to as the “Satan II,” has been delayed. These sources told TASS news agency that “the [silo launch] testing of the Sarmat from the Plesetsk launch facility in March won’t happen… it has been shifted back to the second quarter of 2017, likely in April.” The ICBM, which is meant to replace the SS-18 once operational, will be equipped with 10 heavy nuclear warheads.
