What’s the Justification for the Prompt Global Strike Program? April 27, 2010

The White House requested $250MM for research next year into hypersonic engines that could support a “Prompt Global Strike” (PGS) weapon system later this decade. Air Force General Chilton explains the need for PGS as follows:

Today we can present some conventional options to the president to strike a target anywhere on the globe that range from 96 hours to maybe four, five, six hours. If the president wants to act faster than that, the only thing we have that goes faster is a nuclear response.

Now I think hypersonic engines are as cool as the next geek, but PGS is going to consume many billions of dollars to produce a capability that we have had for half a century: Intercontinental ballistic missiles (ICBMs) can reach any point on earth in under an hour. Yes, today they may all be tipped with nuclear warheads. But it would be a lot cheaper to recommission ICBMs with precision conventional warheads than to build a maneuvering hypersonic cruise missile. And the proposed PGS doesn’t solve any of the strategic problems posed by conventional ICBMs: Russia and China are already protesting that PGS is as destabilizing as our strategic nuclear arsenal.
