More than half of Ukraine’s F-16s are reportedly affected by maintenance uncertainty, according to WSJ. The jets require major inspections after 300 flight hours to service engines, avionics, hydraulics and other systems. Retired US Rear Adm. Mark Montgomery says inspections that normally take 2-6 weeks in the US can take up to 40 weeks in Belgium. At the current maintenance and operational pace, a Western source said Kyiv could exhaust its available F-16 fleet by year-end.
