Russia will begin deploying a new type of long-range missile in 2018 to replace a Cold War version.
Interfax news agency quoted Strategic Rocket Forces commander General Sergei Karakayev as saying a new Intercontinental Ballistic Missile (ICBM) called the Sarmat is being developed to supplant the RS-20B Voyevoda by 2018-2020.
The Voyevoda, whose NATO name is the SS-18 Satan, was developed in the 1970s and the missiles are approaching the end of their service life.
General Karakayev said some of the ICBMs would remain in service until 2022.
A pro-Kremlin newspaper reported on Monday that Moscow has deployed missiles with a range of hundreds of miles in its western exclave of Kaliningrad.
