FWIW, I heard a rumor that Israel is developing stealthy FAST packs for the F-35. These are conformal packs that attach to the sides of the fuselage and carry extra fuel, electronics and weapons. When the Israelis first developed the FAST packs for the F-15, our Air Force bought them and used them to create the F-15E Strike Eagle interdiction aircraft. Boeing is using their own version of the FAST pack in the F-15ES Silent Eagle. If the Israelis can make stealthy FAST packs for the F-35, it would likely mean the ability to carry two additional AMRAAMs or 1,000 pound bombs, as well as several hundred miles more range. That would be a very nice increase in capability.
