HC-130J: Super Hercules
From Globalsecurity.org: The new C-130J has the familiar silhouette, but it is a brand new airplane with the performance to prove it. Compared to the earlier production C-130E, maximum speed is up 21%, climb time is down 50%. Cruising altitude is 40% higher, range 40% longer. With new engines and props, the J can reach 28,000 feet in just 14 minutes. And for tricky low altitude maneuvers, new avionics and dual head up displays make it easier and safer to operate. It also offers reduced manpower requirements, lower operating costs, support costs, and life-cycle costs.
From The Shield of Freedom, 2006: The service took delivery of its sixth HC-130J Super Hercules in 2003 and now operates all six in the HC-130J rescue configuration at Elizabeth City, N.C.
