GR-1
The Global Rocket 1 (GR-1) was a FOBS, Fractional Orbital Bombardment System (FOBS) intercontinental ballistic missile (ICBM) developed but not deployed by the Soviet Union during the Cold War. The system also was given the NATO reporting name SS-X-10 Scrag, and carried a Soviet GRAU index of 8K713. Development In 1961, faced with the prospect of development in the United States of an anti-ballistic missile (ABM) system to intercept conventional ICBMs, the Soviet Union began development of a fractional orbital bombardment system (FOBS) to defeat these interceptors. Soviet Chief Designer, Sergei Pavlovich Korolev designed the Global Rocket 1 (GR-1). The concept was to construct a missile that could be launched into low earth orbit (150 km), from which a 1500 kg nuclear warhead equipped with a deorbit stage could be dropped to its targets in a non-ballistic manner and without giving away its target until final descent. This concept would allow for very little warning to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FOBS
A Fractional Orbital Bombardment System (FOBS) is a warhead delivery system that uses a low earth orbit towards its target destination. Just before reaching the target, it deorbits through a retrograde engine burn. Mark ZastrowHow does China’s hypersonic glide vehicle work? Astronomy, 4 November 2021. The Soviet Union first developed FOBS as a nuclear-weapons delivery system in the 1960s. It was one of the first Soviet efforts to use space to deliver nuclear weapons. In August 2021, the People's Republic of China tested a weapon that combined a FOBS with a hypersonic glide vehicle. 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 150 km. Energetically, this would require a laun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
