The TR-1 Temp is a mobile theatre ballistic missile developed and deployed by the Soviet Union during the Cold War. It was assigned the NATO reporting name SS-12 and carried the industrial designation 9M76. A modified version was initially identified by NATO as a new design and given the SS-22 reporting name, but later recognized it as merely a variant of the original and maintained the name Scaleboard. The Temp entered service in the mid-1960s.

The TR-1 was designed as a mobile weapon to give theatre (front) commanders nuclear strike capability. The weapon used the same mobile launcher (MAZ-543) as the R-11 Scud missile but had an environmental protective cover that split down the middle and was only opened when the missile was ready to fire. All were decommissioned in 1988-1989.
