“As our teammates in Europe and in the Pacific think through their future, their ability to reflect upon the extended deterrence provided to them by the American Triad is an important part of their strategic calculus. We can't on our own just in isolation or unilaterally change that equation and be responsible partners and allies.”

“The challenge for policymakers and strategists is to ensure the triad is credible to deter our adversaries from concluding that a strategic attack is ever worth the cost. A credible nuclear force is one that is reliable, safe, and leverages modern technology to meet the challenges of today and for decades to come. The decision to replace the Minuteman III program with the GBSD program is a welcome move toward this end.”

“Across the Department of the Air Force, we are looking for opportunities to inject innovation into programs to stay ahead of our adversaries,” said Dr. Will Roper, assistant secretary of the Air Force for acquisition, technology and logistics.  “Our GBSD team is doing just that by leveraging a modular open system approach to ensure our net generation ICBM system is adaptable to challenges posed by the pace of technological advancements and new threat environments”
