Isn’t Iron Dome a native, home-grown Israeli solution?
Iron Dome is a native Israeli system, as is Arrow (equivalent to THAAD) and Davids Sling, which is replacing Patriot PAC-2.
All of these however were developed with R&D participation and component sourcing from US companies like Boeing and Raytheon. This is a win-win for both countries as they share R&D benefits.
