The number of tests carried out will double to 12 next year as Russia steps up military preparations, commander Sergei Karakayev said.
Mr Karakayev said: “Five missile launches were carried out in 2017, with another one pending, and 12 launches have been planned for 2018.”
Russia’s troops will also be given 20 Yars missile launchers in 2018, with military chiefs planning to have transitioned to the ballistic missile launchers by 2026.
The upgraded system will allow ballistic missiles carrying multiple independent nuclear warheads to be fired from moving launchers and silos.
Mr Karakayev said: “There are plans to keep the missile complex in service until 2024… Plans have also been made to extend its service time until 2025-2027.”
RS-28 Sarmat missiles could replace the system and could be tested before the end of the month.
News of the military expansion comes after it was revealed Russia is preparing to expand its naval capabilities in the Mediterranean as Vladimir Putin looks to assert his influence in the Middle East and North Africa.
The plans for the base at Tartus on the coast of Syria would allow the facility to accommodate bigger warships.
Currently the base is classed as a ‘repair and replenishment’ facility and can only deal with four vessels at any one time.
But dredging work and new piers would make space for up to 11 warships, as well as Russia’s largest battlecruiser, the nuclear-powered Pyotr Velikiy.
Tartus is Moscow’s only naval base outside of the former Soviet Union, and the warm waters of the Mediterranean would give Russian ships access to the Middle East and North Africa all year round.
The announcement comes just days after Mr Putin ordered a “significant contingent” of Russian troops home from war-torn Syria.
The Kremlin has declared victory against ISIS militants in the Middle Eastern country, though a US-led coalition disputes this.
Moscow has been supporting Syrian President Bashar al-Assad in the bloody civil war which has raged for more than six years.
And as a ‘thank you’ for the backing, Damascus gave the green light to an expansion of the Tartus base in January.
And as part of the agreement, Russia would be allowed to use the facility for 49 years.
Russian submarines lurking in the Mediterranean have been spotted launching cruise missiles against ISIS targets in recent months.
