Hi Melvin,

This simply look's like it could be a back facing radar (look at pic's of the SU's & you will see similar things)which allows the F-16 to perform their W-W missions, it looks also as though it has intergrated and improved ECM. If you think logically you will know what this does Melvin, when you are flying a Wild Weasel in enemy sky's you are in a dangerous situation because of the SAM's, you need to take them out first & this equipment helps foil their Radars/missles into not striking your aircraft. If it is classified then you will not find much info on this unfortunately, but keep looking there's always things on the net that give you a bigger picture of what's happening.
