Another three year delay for the F-35

Aviation week
"....Another three-year slip to initial operational test and evaluation, the culmination of system development and demonstration, which now is due to be complete in 2019 – the target date is February but the threshold date is October."

News - First F-22 Squadron get Combat readiness

But it wasn’t until this month that the first squadron of Lockheed Martin-built F-22s was fully combat-ready with ground-mapping radars and a flexible bomb payload — standard equipment on most Air Force strike jets.
