As of Feb. 22, Air Combat Command has 63 F-16s with cracked bulkheads, noted ACC boss Gen. John Corley. Fortunately, even though some of these Vipers are grounded, the problem is not as severe as it is for the F-15s that have defective longerons. The difference, he explained, is that ACC’s analysis predicts that an F-16’s cracked bulkhead does not create a structural “single point failure” that will lead to a catastrophic failure. Nonetheless, the problem needs to be fixed as the F-16s go through depot, and the number of affected fighters, which changes constantly, has been trending upwards.
U.S. Air Force F-35A Lightning II stealth fighter jets were observed flying toward the Middle East on Feb. 11, the latest step in the U.S. military buildup in the region as the Trump administration weighs possible strikes on Iran.
