Israel has invented the "Iron Beam" which recently had a 90% knockdown rate of missiles, rockets and other airborne destructive devices. The cost s *gasp* $3.50 per shot compared to the Iron Dome at tens of thousands of dollars to intercept a single rocket or missile! That sounds like it would make the Iron Dome obsolete and infuriate Iran and quite possible Russia since the relationship between Russia and Israel isn't the best of late.
