A new image was posted to Twitter by Boeing showing the F-15 with a nose mounted IRST. Though this isn't an official confirmation of a nose mounted IRST, it must be on somebodies mind for them to publish a photo with an IRST in the nose.
I wonder if the US Air Force will adopt a nose mounted IRST for a future variant of the F-15 EX? The lack of integrated IRST has been of concern for a while now on US Air Force and Navy jets, especially as they played an important role in pioneering the technology on the F-14.
