Company test pilot George Krebs makes the first flight of the North American XB-45 Tornado at Muroc AAF, Calif. The B-45 is the first American four engine jet bomber to fly and it is the first USAF jet bomber to go into production.
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.
