The F-35 Lightning II Joint Program Office (JPO) leads the life-cycle program management of the F-35A, F-35B, and F-35C; the fifth-generation joint strike fighter (JSF) air system of choice for the U.S. Air Force, U.S. Navy, U.S. Marine Corps, international partners and foreign military sales customers.

The mandate of the JPO is to deliver a capable, available, and affordable air system to the warfighter - outpacing key competitors to win tomorrow's high-end fight as we develop, deliver, and sustain war-winning fifth-generation capabilities at high-end fourth-generation costs.
