In April 1965, Douglas made an announcement on the three new fuselage stretches for the DC-8. Named as the Super Sixties, the three new types are the Douglas DC-8-61, the Douglas DC-8-62 and the Douglas DC-8-63. The Super Sixties brought life to the DC-8 program that was on its verge of closing.
After the production of the DC-8-61 followed by the DC-8-62 in April 1967, the last variant of the Super Sixties known as the Douglas DC-8-63 entered into service in June 1968.
Production of this version includes 41 units of DC-8-63s, 53 units of DC-8-63CF, 7 units of DC-8-63AF and 6 units of DC-8-63PFs.
107 units of DC-8-63 were constructed that made it the most prominent version among the Super series of the DC-8. The following airlines are the customers for the DC-8-63:
