handsome plane but I have a question; is the F-16 modified?

The F-16 is normally a single-seater. Perhaps this is a two-seat training variant. It also looks like they've added the two large pods just aft of the cockpit. Those aren't on any F-16 that I've ever seen.

It’s an F-16I: http://www.israeli-weapons.com/weapons/aircraft/f-16i/F-16I.html

Those are conformal fuel tanks which are becoming more common and quite a few dual seat F-16s are operational as both trainers and tactical platforms.
