The C-130J Super Hercules offers superior performance and new capabilities, with the range and flexibility for every theater of operations and evolving requirements. This rugged aircraft is regularly sent on missions in the harshest environments, and is often the first aircraft to touch down, usually on austere landing strips before any other transport to provide humanitarian relief after natural disasters.
With more than 1.2 million hours of flying combat, humanitarian, special operations, aerial refueling, firefighting, and search and rescue missions around the world, the C-130J stands ready for its next mission and for whatever the future holds.
