Grounded jets and political spats as the Islamic State regroups

Last year, Iraqi F-16 fighter jets would swoop across the wide deserts of Anbar province twice a week, surveilling militants from the self-proclaimed Islamic State (IS) group. The pilots were “watching for leaks” across the Syrian border before heading back to the Balad airbase north of Baghdad, said a senior Iraqi official directly familiar with the program.

Now Iraq’s F-16 program “is almost gone,” the official said in interviews this month outlining the state of the high-profile fighter jet program. Three senior Western security officials familiar with the program confirmed that the program's operational effectiveness is diminished.
