Thanks for the info! I perhaps incorrectly remembered the GBU-38 discussion I had with Calvin; it was years ago. Wish him well if you are in contact; I met him on TankNet but haven't seen him there for a year or so.
I never really knew him well, just ran into him a few times in the hallways in the squadron, chatted and knew who he was. How many, GBU-38's can a 10 by carry is an academic discussion these days, since a rotary can carry up to 16 or mix and match with 2000 lb class weapons.
I had seen a photo where they were carried that way as a test (they looks like they were slightly staggered on the rotary position) but I didn't know that upgrade/carriage was fleet wide. Thanks again.
NP, Libya was the first time that mod was used IIRC. Pretty sure there's something on the AF webpage about it if the archives go that far back...
