Ballistic missiles with a range of over 5,500 km. The Soviets specialised in their ICBM capability quite considerably- Russia still does. Remember that they put satellites into space before the US- and many of their space launchers are modified ICBM designs. In fact, like the US, some satellites are actually old missiles. The Soviets also developed something the US didn't- "heavy ICBMs" with lots of big warheads on. There were also plans for "monster ICBMs" with warheads of over 100 megatons. Acronyms: * R- "Rocket" * UR- "Universal Rocket"
