There is no question that America needs to invest in keeping its nuclear deterrent credible, said Paul Huessy, an expert on nuclear weapons at GeoStrategic Analysis. In his view, however, the missile industrial base is less of a concern than retaining the ability to develop an actual nuclear warhead, he said. Huessy and Barry Watts at the Center for Strategic and Budgetary Assessments say that programs like the EELV or refurbishment programs for existing missiles are probably sufficient to keep ICBM and SLBM design skills alive. Huessy said that there are many components on the U.S. Air Force Minuteman III, for example, that are being replaced—which requires many of the skills needed to design an entirely new weapon. “They have all sorts of ideas on how to build a Minuteman [replacement],” he said.
