The Fractional Orbital Bombardment System (FOBS) was a nuclear-weapons delivery system developed in the 1960s by the Soviet Union. One of the first Soviet efforts to use space to deliver weapons, FOBS envisioned launching nuclear warheads into low Earth orbit before bringing them down on their targets.
Like a kinetic bombardment system but with nuclear weapons, FOBS had several attractive qualities: it had no range limit, its flight path would not reveal the target location, and warheads could be directed to North America over the South Pole, evading detection by NORAD's north-facing early warning systems.
The maximum altitude would be around 150km. Energetically, this would require a launch vehicle powerful enough to be capable of putting the weapon 'into orbit'. However the orbit was only a fraction of a full orbit, not sustained, and so there would be much less need to control a precise orbit, or to maintain it long term.
