re: F-35 Lightning ll
Several models to choose from based on the X-35. One has vertical landing capabilities that exceed the Harrier's overall performance.
Specifically the F-35’s requirements are that it be: four times more effective than legacy fighters in air-to-air combat, eight times more effective in air-to-ground battle combat, and three times more effective in reconnaissance and suppression of air defenses. These capabilities are to be achieved while still having significantly better range and a smaller logistical footprint than legacy aircraft.
F-35 Lightning name originated from the P-38 fighter.
