USAF adds IRST to F-15s

They will be using a variant of the ANS-42 Ifra-Red Search and Track system originally deployed on the F-14D (replacing the TCS used on earlier models) and subsequently installed on the front half of an F-18 drop tank (probably because the under-wing environment was too vibration prone).

It seems like a sound move, though with the USAF shoving F-15s and F-16s out the door as quickly as possible so as not to compete with the F-35 JSF, I'm a bit dubious.

My earlier posts on this are here and here.
