The Air Force Research Lab is studying how objects fly at hypersonic speeds at sea level, a capability that could eventually lead to new warhead technologies. “We already have things in place with people who are doing the warhead work, so it’s not something that we ‘hope’ to use someday, it is something that the warhead designers … have already given me problems to work on,” said Kirk Vanden, technical advisor for AFRL’s Munitions Directorate computational mechanics branch. The Vanden team’s work centers on examining penetrator warhead flows at speeds around Mach 6 and involves “an exciting new application of nontraditional hypersonic computational analysis,” said John Schmisseur, Air Force Office of Scientific Research program manager overseeing hypersonics grants. AFOSR is funding Vanden’s work.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
