The U.S. Air Force has released new images of its F-15E Strike Eagle fighters returning to combat air patrol missions over the U.S. Central Command area of responsibility.
The photos, taken during aerial refueling operations, sparked debates on social media about the condition of the aircraft.
In a statement, the Air Force said, “The F-15E Strike Eagle’s presence promotes regional stability and security, demonstrating the U.S. commitment to protecting its interests and maintaining a strong defensive posture in the region.”
However, the images drew attention to visible streaks and surface wear on the aircraft. Observers pointed out what appeared to be corrosion or rust on the wings of both jets in the photos. Commentators expressed concern over the state of the airframes, noting the apparent degradation of their painted surfaces.
Some social media users speculated that the streaks might indicate rust, but others countered that the F-15E’s airframe, constructed primarily from aluminum and titanium, is not susceptible to rust. One user noted that the material in question could be radar-absorbent coatings, which can deteriorate under extreme environmental conditions.
Later, U.S. Air Force sources confirmed that the outer coatings on some fighters have shown signs of wear due to prolonged exposure to harsh weather. The combination of intense sunlight, sand, and saltwater vapor in certain deployment areas can accelerate the degradation of surface layers.
Despite the appearance, Air Force officials maintain that the aircraft remain fully mission capable and that any cosmetic wear does not compromise operational performance. Maintenance teams routinely inspect and service the Strike Eagles to ensure combat readiness, the service said.
Is this rusted surface normal?

The F-15E Strike Eagle has been a core component of U.S. airpower in the Middle East for decades. Designed for both air-to-air and air-to-ground roles, it continues to support missions in volatile regions where air superiority and precision strike capabilities are critical.
