The F-15EX is the latest development of the F-15E Strike Eagle.  It features modernized avionics, radar, weapons systems, and new engines packed inside a 20,000 flight hour airframe.  Fly-by-wire flight controls enable payloads on stations 1 and 9 (previously unused), allowing the F-15EX to carry up to 12 air to air missiles, though AMBER racks could theoretically increase this to 20.
Unfortunately I can only include one livery with this mod due to file size limitations.  The others are available on the User Files as well as in a separate livery pack here:

Version 2.0 comes with the custom cockpit from @musolo, as well as the AIM-260A JATM and support for currenthill's AIM-174B missile mod.  It is otherwise very similar to the previous release Version 1.8.7.
Installation: Just extract the .7z file and drop it into Saved Games/DCS/mods/aircraft (or Saved Games/DCS.openbeta/mods/aircraft depending on which version you have).   This mod has been tested with DCS 2.9 as of 11/10/22.
 

AIM-7N Sparrow (What If) for SF2, any/all.  What if the nuclear warhead element of the Sparrow X project was carried over to a version of the AIM-7F?
Installation: Just drop into your mods folder and go fly.  Tested using the F-4T Air Superiority mod by dtmdragon, but should work with any AIM-7-capable aircraft.
