The US Air Force included in its budget for 2026 funds to study the integration of external fuel tanks into the F-35 hunt, resuming an old project that never left the paper.
The measure aims to broaden the radius of action of aircraft, especially in long range missions, where air replenishment can be risky. The initiative is part of Block 4 modernization, which already foresees radar updates, weapons and electronic systems. Although external tanks reduce jet stealth, they can be essential in scenarios where range is a priority.

The idea is not new: the Lockheed Martin It had already developed sublocate tanks between 2004 and 2007, but aerodynamic problems led to the cancellation of the project. Recently, Israel has worked in conformal tanks (CFTs) and ejectable models for its F-35i variant, aiming at unpaid attacks against distant targets such as Iran. Now, the US evaluates both loose tanks and CFTs, but there are no details on deadlines or costs.
The project can benefit especially the Navy F-35C, as the sixth generation f/A-XX fighter program has been suspended.
In addition to extending reach, external tanks would allow longer patrol time and reduce tanker aircraft dependence, increasingly vulnerable in modern conflicts. The Air Force also seeks alternatives such as refueling drones and flight replenishment systems coupled to other fighters. Meanwhile, the Block 4 program faces delays due to problems with Technology Refresh 3 (TR-3), update required before the new capabilities.
The Pentagon has confirmed that all F-35 variants are being considered to receive the tanks, but there is no set schedule yet. The decision reflects the growing US concern with operations in Indo-Pacific, where longer distances and anti-aircraft threats require jets with greater autonomy.
While the F-35 already exceeds many conventional fighters in reach and stealth, external tanks can be the key to even more strategic missions in the future.
