Re: F-35B & KC-130 Mid Air

Well the KC-130 can refuel from the KC-46, and nearly every plane that can refuel using H & D can do it on either. Can the KC-130 refuel off the boom? I don’t believe it can. HC-130J can do it though. Air Force units flying the HC-130 have the low speed drogue. This limits them to refueling hel...

Re: Is this a standard C-130H? (Wyoming ANG)

Appears to be a plain jane C-130 that has been modified to support LAIRCM, an anti IR missile system.

I don’t see the laser turret though. I’d suggest to you that LAIRCM has been removed while aircraft is in its fire fighting role. The portions that are removable anyway.
