Lists on the subject

development

The UR-100MR was created as the successor system to the UR-100 (NATO code: SS-11 Sego). It was introduced to the Soviet missile forces in 1975 . The new system was designed to combat bunkered targets such as missile silos and command bunkers. A total of 150 systems were produced. All missiles were stationed in former silos of the previous version UR-100. Because the UR-100MR was longer than its predecessor, its tip could be folded to the side. Immediately before take-off, the tip of the guided weapon was raised.

technology

All versions were two-stage liquid -propelled rockets . The UR-100MR, like the previous model UR-100 or the R-36M, also from OKB Jangel, used the liquid and storable UDMH as fuel and nitrous tetroxide as the oxidizer. The warheads were mounted on a so-called post-boost vehicle (PBV) as a bus . The missile was controlled by an inertial navigation platform . An accuracy of hit ( CEP ) of 450 m to 900 m was achieved.

The UR-100MR was the first of its kind to use the “cold” starting procedure. The missile is ejected from the silo by means of compressed air. During this initial process, the engine ignites outside the silo. This technology saves fuel and prevents damage to the silo.

status

In 1986 SS-17s were stationed in the Kostroma area and near Osjorny (Jedrowo). The last system was phased out in 1997.
