Instead of pursuing its own fighters, Israel has lately preferred to extensively modify the aircraft it buys from the United States. The F-15I “Thunder” and the F-16I “Storm” have both received major upgrades to optimize them for Israeli service. Both planes have increased range and improved avionics, enabling the IDF to fight effectively at great distance from its bases. The F-15I, a variant of the F-15E Strike Eagle, is the IAF’s most important long-range strike platform. The IAF has already undertaken steps to make the F-35 Joint Strike Fighter more suitable for Israeli service, including advanced software modifications.
