Creo que el problema es que el proveedor quiere un volumen de suministro mensual estable; no está dispuesto a tener capacidad ociosa que aumente los gastos generales. Esto también se conoce como fabricación en cadena de montaje «justo a tiempo».

The U.S. Department of Defense (DoD) and the F-35 Joint Program Office (JPO) own and pay for F-35 spare parts. These parts are pooled globally. Primary contractor Lockheed Martin manages the logistics and ordering through centralized sustainment contracts.
The F-35 parts bottleneck involves 48 specific spare parts that the supplier base currently cannot produce in sufficient quantities to meet global fleet demand. These chronic supply shortages are the primary driver of the fleet's low availability, frequently forcing maintenance crews to "cannibalize" parts from other aircraft.

The interesting detail is that this $13.7 billion is not merely for “progress”. In reality, a large portion covers previous shortfalls: the report specifies that $7.3 billion would go towards spare parts and repair stocks, $3.1 billion towards the activation and expansion of depot capabilities, and $3.3 billion towards operations and maintenance. It adds that the services had budgeted 38.1 billion for 2027–2031, whereas the estimated requirement was 50.8 billion, representing a potential shortfall of around 12.7 billion.
