It also had a fast reaction time, being able to fire in approximately five minutes, and was nearly impossible to intercept, thereby allowing it to penetrate defenses.

[6] During the mid-1960s the Soviets began developing a replacement for the R-17 Elbrus (NATO reporting name: SS-1C Scud B), which had some serious drawbacks including slow launching time, dangerous fuel,[b] and poor accuracy.

The 9M714, designed as an extended range version of the Tochka, used solid fuel which could be quickly loaded and fired with a smaller crew and less support vehicles.

It could carry a conventional high explosive fragmentation (9M74F), cluster munitions (9M74K), chemical, or nuclear (9M63) warheads.
