As the nation weighs the future composition of its nuclear deterrent force, it’s important to remember that reductions in numbers of warheads and platforms can change the whole decision calculus of potential adversaries, Maj. Gen. William Chambers, assistant chief of staff for strategic deterrence and nuclear integration, said Tuesday at AFA’s Air & Space Conference in National Harbor, Md. “What we like to say is less is not just less; less is different,” he said. That’s why adaptation to the new security environment and maintaining “a diverse set of attributes and capabilities” remains critical “as the attributes of the force structure may become more important than sheer numbers.” For example, while ICBMs and submarine-launched ballistic missiles “will remain crucial to providing stability with nuclear peers and near peers, their high threshold may diminish their credibility in regional contingencies,” he explained. “Lack of credible capabilities, especially to provide extended deterrence against non-peers and regional actors invites instability.” That’s where nuclear-capable aircraft, such as the dual-role fighters that support NATO, come in. “Aircraft capable of deploying both gravity and standoff nuclear weapons are credible in the eyes of several potential adversaries,” said Chambers. In the future, too, Chambers said bombers may “carry an increasing role in extended deterrence.”
Adm. Christopher Grady, vice chairman of the Joint Chiefs and head of the Joint Requirements Oversight Council, is pushing a “portfolio” approach to requirements and wants his position to have “more teeth” so he can enforce it.
