The United States Air Force is facing a technical issue with its new F-15EX Eagle II fighter jets, manufactured by Boeing. Reports indicate that some aircraft have been temporarily grounded due to an abnormal fuel leak from the wings.

Boeing has confirmed it is testing possible solutions, including adjustments to valves and connections, while investigating whether the issue is related to defective parts or assembly failures.
Although fuel leaks are common in aircraft due to pressure and temperature variations, the level recorded in the F-15EX was considered above expected.
Experts warn that if not corrected, the defect could compromise mission safety. It is still unclear how many of the nine units delivered so far have been affected or why the issue was only detected after years of testing.
The situation is concerning, as Boeing is already facing delays in other military projects, such as the VC-25B presidential jets and the KC-46 tankers.
Meanwhile, a strike by employees of Boeing’s defense division, which began this week, may impact efforts to resolve the issue. Despite the setback, the company assures that the F-15EX program remains a success, with advanced testing and interest from international buyers. The aircraft, set to replace the aging F-15C fleet, is already being operated by the Air National Guard and will soon be deployed to Japan.
Boeing hopes to resolve the matter quickly to avoid further impact on the delivery of the 129 units on order.
