UR-100 / SS-11 SEGO . The development of the massively deployed UR-100/SS-11 liquid propellant light ICBM was the centerpiece of a major Soviet effort to reach numerical strategic parity with the USA. The SS-ll was the Soviet counterpart of the US Minuteman system in quantity, size and purpose.

antitank guided missile, medium or long-range missile whose primary purpose is to destroy tanks and other armoured vehicles.

The UR-100 missile developed at Vladimir Chelomei's design bureau in the town of Reutov near Moscow became the most numerous ICBM deployed in the Soviet Union during the Cold War. Since mid-1960s, several generations of the UR-100-based missiles have been developed.

Tolubko emphasised raising the physical fitness standards within the SRF and in the late 1970s and early 1980s, the Strategic Rocket Forces began to field the new UR-100 (SS-11 'Sego') and UR-100N (SS-19 'Stilleto') ICBMs beginning with the 43rd Rocket Army in the Ukrainian SSR, providing them with longer range and more accurate missiles.

The UR-100N, also known as RS-18A, is an intercontinental ballistic missile in service with Soviet and Russian Strategic Missile Troops. The missile was given the NATO reporting name SS-19 Stiletto and carries the industry designation 15A30. [5]

The SS-11 Sego (designated the UR-100 in Soviet/Russian service) was the heart of Moscow's attempt to achieve numerical strategic parity with the U.S. in the 1960s. The liquid-propellant ICBM filled the same role in Soviet service as the U.S. Minuteman system.
