The TR-1 Temp (Russian: Темп-С, Temp-S, meaning 'Speed') was 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 Scaleboard and carried the industrial designation 9M76 and the GRAU index 9К76. 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-17 Elbrus 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 as part of the INF treaty banning such weapons.[1]
