Scenario description
Assume that by the resolution date, the B-21 final-assembly expansion at Air Force Plant 42 in Palmdale is reported to face a material execution, labor, supplier, construction, funding, cost, or schedule constraint that slows or limits its near-term contribution to bomber production. The initiating change must be a reported operational or procurement constraint affecting the Plant 42 B-21 final-assembly ramp, not simply uncertainty about future production rates. The known current scope remains the reported more-than-1-million-square-foot facility expansion; exact cost growth, schedule slip, workforce shortfall, supplier quantities, or delivery impacts are left as reported if disclosed and are not assumed here.
