Conventional Prompt Strike (CPS),formerly called Prompt Global Strike (PGS),is a United States military effort to develop a system that can deliver a precision-guided conventional weapon strike anywhere in the world within one hour,in a similar manner to a nuclear ICBM. Such a weapon would allow the United States to respond far more swiftly to rapidly emerging threats than is possible with conventional forces. A CPS system could also be useful during a nuclear conflict,potentially replacing the use of nuclear weapons against up to 30% of targets. The CPS program encompasses numerous established and emerging technologies,including conventional surface-launched missiles and air- and submarine-launched hypersonic missiles,although no specific CPS system has yet been finalized as of 2018.
