Lockheed Martin Corp has been awarded a contract worth nearly $969 million to build 17 C-130J military transport aircraft, the Pentagon said on Tuesday. The work is expected to be completed by April 2020, the Department of Defense said in its daily digest of major contract awards. Last month, Lockheed announced that it had reached a verbal agreement with the U.S. Air Force for a five-year contract to build up to 83 C-130 J Super Hercules transport planes for the Air Force, Coast Guard and Marine Corps through 2020.
