This was reported by the Defense Intelligence of Ukraine.
On November 1, Russia conducted an unsuccessful test of the RS-24 Yars intercontinental ballistic missile, a nuclear weapons carrier.
A combat crew of the 33rd Missile Army of the Strategic Missile Forces of the Russian Armed Forces launched the Yars missile from the Plesetsk cosmodrome (Arkhangelsk region) at a target at the Kura test site (Kamchatka). It went off course, as it had during previous command and control exercises of the strategic nuclear forces of the aggressor state on October 25.
On October 25, a test launch of the RSM-56 Bulava ballistic missile from the Borey submarine missile cruiser failed.
According to the Defense Intelligence of Ukraine, the Kremlin also has problems with the RS-28 Sarmat heavy intercontinental ballistic missile. It is one of the key projects in the program of modernization of the Russian strategic nuclear forces.
