The Test Cell at Little Rock AFB is used to test Allison/Rolls Royce T-56 turboprop engines that power C-130E/H Hercules airlifters. Little Rock Air Force Base is the center of the C-130 world, where pilots literally from around the world come to learn the ways of the mighty Hercules, more affectionately known as the HERK. We work hard, but we have a little fun too. :)
