In 1976, the improved UR-100NUTTKh (NATO designation SS-19 Mod 3) version entered development with flight tests in the later half of the decade.

The UR-100N is a fourth-generation silo-launched liquid-propellant ICBM similar to the UR-100 but with much increased dimensions, mass, performance, and payload.

Once the cause was unambiguously identified and corrective measures implemented, Rokot returned to active service on 28 July 2006, with the successful launch of an earth observation satellite for South Korea.

The treaty required the Soviet Union to begin the process of dismantling nuclear warheads and the launchers used for UR-100N missiles.

On May 31, 1996, the final train left Ukraine for Russia laden with the last of approximately 1,800 warheads, including more than 400 weapons from the 46th Bomber Army.
