How Many Hours Can The F-35 Fly On Internal Fuel?

The F-35’s time aloft on internal fuel depends on which variant is flown and how the aircraft is configured. The baseline loiter and range figures span roughly 900 to 1,500 nautical miles, translating to about 3.5 to four hours of flight time. When tasked for combat radius—fully loaded with armaments and flying a high-performance profile—that endurance drops by about half to two-thirds, leaving an estimated 500 to 700 nautical mile range depending on variant and mission. The article contrasts the F-35A land-based model, the STOVL-capable F-35B, and the carrier-suited F-35C, noting practical range differences tied to operating profiles.
