Air Force leadership rolls out a new strategic plan today. “America’s Air Force: A Call to the Future” is a 30-year plan that focuses on four key points the Air Force believes will shape the future of air power. But their plan isn’t entirely a new concept. Russell Rumbaugh is Director of Budgeting for Foreign Affairs and Defense, and Senior Associate, at the Stimson Center. Russell and his colleague Barry Blechman from Stimson wrote in Breaking Defense about a concept called Strategic Agility. On In Depth with Francis Rose, he explained the connection between today’s plan — as introduced by Secretary James and General Welsh — and the work he and Barry have done.
