The Air Force reportedly is still considering the use of Minuteman ICBMs fitted with conventional warheads to answer the quick global strike requirement, but service, industry, and congressional stakeholders alike remain skittish, believing such a capability would make everyone else in the world very nervous.

The Air Force budget would grow to $234 billion while Space Force spending would shrink to $26 billion under the White House's yearly ask.
