Scenario description
Assume that by the resolution date, the U.S. Air Force, Northrop Grumman, or authoritative defense procurement reporting indicates that the new Air Force Plant 42 B-21 final-assembly expansion in Palmdale is being converted into a materially faster production or delivery ramp. The initiating change must be more than the already reported groundbreaking: it includes an announced acceleration of B-21 delivery cadence, a funded production-rate increase, earlier-than-previously-expected transition of B-21 final assembly into the expanded Plant 42 facilities, or newly awarded production/infrastructure work explicitly tied to faster B-21 bomber output. The reported expansion remains more than 1 million square feet; exact bomber quantities, delivery rates, and contract dollars are left as reported if disclosed and are not assumed here.
