Breaking Defence has an interesting article about the problems the US has in integrating the newer APG-85 radar into the F-35 airframe vs the earlier APG-81. Because of these complications, some F35s will be flying without a radar, which restricts them to non-combat roles.
It will be interesting to see how this impacts foreign sales.
Rep. Rob Wittman told Breaking Defense that while he expected issues with the new APG-85 radar to eventually be resolved, in the interim the US military will be left with “lots of aircraft out there, but not ones that are ready to go to the fight.”
