Delivery is expected by April 2020, according to the DoD.
Earlier this year, Lockheed Martin announced that it had reached a tentative agreement with the USAF for a five-year contract to build up to 83 of the aircraft for the USAF, the US Coast Guard, and the US Marine Corps.
C-130Js are able to land on unimproved runways, so they are frequently used for humanitarian relief missions, and special operations missions. They are also able to provide aerial refuelling, close air support, and search-and-rescue capability.
The Lockheed Martin C-130J Super Hercules is a four-engine turboprop military transport aircraft. The C-130J is a comprehensive update of the Lockheed C-130 Hercules, with new engines, flight deck, and other systems.
