In a decade or so, a new harbinger of atomic doom and deterrence will squat in Minuteman III missile silos in Nebraska and four other upper Midwest states.

Now the next-generation ICBM has a name: Sentinel. Until last week, the Pentagon called the nuclear-tipped intercontinental ballistic missiles currently in development by the moniker “Ground-Based Strategic Deterrent,” or GBSD.

On Tuesday, Air Force Secretary Frank Kendall announced that they will be called by the slightly less awkward name LGM-35A Sentinel.
