J-35 is still the Saab Draken in my book, but you mean the JSF or F-35
Yes, but it is a Joint Strike Fighter, which means a strike fighter for all three services. So the F-35A conventional take-off and landing variant will replace the F-16 and A-10 of the Air Force. The F-35B SVTOL will replace the Harriers of the USMC. And the F-35C carrier capable will replace the F/A-18C/D of the US Navy and USMC.
Yes, the Raptor is only replacing the F-15C/D fighters, so that's why they still needed a more economical F-16 multi-role replacement.
Exports will probably consists of mostly F-35As, maybe even downgraded for some countries, and F-35Bs. I don't think there is a big market for the F-35Cs.
