The US Air Force is assisting Lockheed Martin, Pratt & Whitney, and the Israeli Air Force in determining the source of a type of formaldehyde found in IAF F-16 fighters, reports the Jerusalem Post. The problem erupted earlier this year when Israeli pilots noticed a strange smell in one fighter that later proved to be a type of formaldehyde that is known to cause cancer, prompting the IAF to ground the fighters. The US Air Force has not had a similar problem with its F-16s, according to Air Combat Command boss Gen. John Corley. The IAF is installing special filters that appear to work to eliminate the problem in some of the aircraft but not all.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
