Missile Envy: Modernizing the US ICBM Force

The USAF has claimed it is not looking at a road-mobile option for its next-generation intercontinental ballistic missile (ICBM). Under the Ground-Based Strategic Deterrent (GBSD) program the aging Minuteman III ICBM fleet will be replaced. Speaking about the mobile option, a service official said “We want to make sure that as we look at GBSD, we’re building it modular so if changes need to be made in the weapon system you don’t have to open up, let’s say, the software to redo the entire software.”

For 50 years, land-based Intercontinental Ballistic Missiles (ICBMs) have been part of the US primary strategic deterrence capability, the nuclear-armed triad that also includes submarine-launched ballistic missiles and long range heavy bombers.

Although the main target for the US deterrent – the Soviet Union – imploded in 1991, other threats – such as nuclear-armed rogue states and non-state actors – have emerged. To address these new threats, the US Air Force undertook a major ICBM modernization program.
