The UPL, which was obtained by Air Force Magazine but not released by the department, lists eight priorities the service wants but couldn’t afford in its 2023 budget request, released in late March. The F-35 is fifth on that list.
Lockheed Martin and the F-35 Joint Program Office have agreed that F-35 production will peak at 156 jets per year in 2023 and remain at that level "for the foreseeable future." The "re-baselining" of the program is meant to ensure predictability and stability in production.
