|Prompt Global Strike (PGS) is a United States military effort to develop a system that can deliver a precision-guided conventional weapon airstrike 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.
|Possible delivery systems for PGS warheads include:|
1) a rocket similar to existing ICBMs, launched from land or via submarine
2) an air- or submarine-launched hypersonic cruise missile
3) a kinetic weapon launched from an orbiting space platform
The Advanced Hypersonic Weapon (AHW) is a demonstrative long-range glide vehicle capable of flying within the planet's atmosphere at hypersonic speed. This capability will ensure the US can attack high-value targets or transient targets at the beginning of a conflict. The AHW technology demonstration programme is managed by the US Army Space and Missile Defence Command (USASMDC) / Army Forces Strategic Command (ARSTRAT).
|The AHW is designed to provide a 6,000km range with 35 minute time-of-flight and achieve less than ten metre accuracy. It delivers a conventional payload at medium and global ranges, using a hypersonic glider.|
The weapon's high manoeuvrability allows it to avoid flight over third party nations when approaching the target. It employs a precision guidance system to home in on the target.
|Russia has been working on the Yu-71 hypersonic vehicle for the last several years. Russia conducted the latest test of its hypersonic missile in February. Russia could produce up to 24 nuclear-capable Yu-71 between 2020 and 2025. Russia is planning to deploy both nuclear as well as conventional configuration.|
China has conducted flight tests of a 7,000 mile-per-hour maneuvering strike vehicle, the Wu-14 Hypersonic missile. China was also testing extreme maneuvers of a mach 10 (7860 mph) prototype.
