The number is not a metaphor. According to Zachary Krevor, CEO of Stratolaunch, a Chinese hypersonic missile targeting either U.S. coast would leave 'about 10 minutes of warning time.' Ten minutes. That is the window inside which the United States would need to detect, track, and intercept a weapon that Beijing has spent years perfecting.
Krevor made the remarks in a conversation with Aaron MacLean, national security analyst at CBS News and host of the School of War podcast, published by The Free Press. The exchange covers how hypersonic weapons work, the emerging reality of AI-enabled missile 'swarms,' and what the United States is — and is not — doing to close the gap.
Stratolaunch, the company Krevor leads, is building vehicles designed to help the Pentagon learn to detect, track, and intercept hypersonic threats. The work is urgent. According to Krevor, China and Russia have outpaced the U.S. in hypersonic weapons development. That is not an opinion floated by a think tank. It is the stated assessment of the man whose company is contracted to help fix the problem.
The mechanics matter here. Hypersonic weapons travel at speeds exceeding Mach 5 — five times the speed of sound — and many are maneuverable, meaning they do not follow the predictable ballistic arc that existing missile-defense architecture was built to intercept. Traditional early-warning systems were designed around a different threat. The physics have changed. The infrastructure has not kept pace.
The AI-enabled swarm dimension compounds the problem. If a single hypersonic missile compresses decision time to ten minutes, a coordinated swarm of them — guided and adapted in real time by machine learning — does not merely multiply the threat arithmetically. It challenges the entire logic of point defense. You cannot shoot down what you cannot track, and you cannot track what you cannot see coming.
Krevor's company is working on the testing and evaluation side of the equation: building the platforms that allow the Pentagon to practice against realistic hypersonic conditions. The United States cannot develop effective countermeasures without first being able to simulate the threat at scale. That is the gap Stratolaunch is trying to close.
The record here is public, and it is not reassuring. The United States has invested heavily in legacy defense systems built for a threat environment that no longer defines the frontier. Meanwhile, peer competitors have moved. The question is not whether hypersonic weapons represent a genuine strategic challenge — the evidence is settled. The question is whether American institutions can move fast enough to answer it.
Follow the incentive, not the press release. A defense establishment that rewards procurement cycles over rapid iteration, and that measures success by budget allocation rather than operational readiness, is structurally ill-suited to close a gap that requires speed above all else. Krevor and Stratolaunch represent the kind of private-sector, mission-driven capability that the Pentagon increasingly needs to partner with — not manage from a distance. The ten-minute clock does not pause for committee review.
