Early design phase

During mid-1952, Douglas opted to covertly begin work on definition studies for a jet-powered transport aircraft. The company's design team examined various arrangements, including some that closely resembled the Comet.
By mid-1953, the team had settled on a form similar to the final DC-8; an 80-seat, low-wing aircraft powered by four

While Douglas remained lukewarm about the jet airliner project, it believed that the USAF tanker contract would go to two companies for two different aircraft, as several USAF transport contracts in the past had done. In May 1954, the USAF circulated its requirement for 800 jet tankers to Boeing, Douglas,

Donald Douglas was reportedly shocked by the rapidity of the decision which, he claimed, had been made before the competing companies even had time to complete their bids. He protested to Washington, but without success.
Having already started on the DC-8 project, Douglas decided that the best option was to press on than abandon the project.
[Norris and Wagner 1999, pp. 12-13.] Following consultations with the airlines, several design changes were made, such as the fuselage being widened by to permit six-abreast seating, which in turn led to larger wings and tail surfaces being adopted along with a lengthening of the fuselage. The existence of the DC-8 was formally announced on 7 June 1955; at the time of the announcement, the development costs had been forecast to be roughly $450 million.
[Norris and Wagner 1999, p. 13.] Four versions were offered to begin with, all with the same long airframe with a wingspan, but varying in engines and fuel capacity, and with maximum weights of about 240,000–260,000 lb (109–118 metric tons). Douglas steadfastly refused to offer different fuselage sizes. The maiden flight was planned for December 1957, with entry into revenue service in 1959. Aware that the program was lagging behind Boeing, Douglas began a major marketing push to promote its new jetliner.

Entry into service

On September 18, 1959, the DC-8 entered service with Delta Air Lines and United Airlines.
[Norris and Wagner 1999, p. 16.] According to the Delta Air Lines website, the air carrier was the first to operate the DC-8 in scheduled passenger service. By March 1960, Douglas had reached its planned production rate of eight DC-8s per month. Despite a large number of DC-8 early models being available, all used the same basic airframe, differing only in engines, weights and details; in contrast, the rival

Further developments

During the early 1960s, Douglas began considering stretching the DC-8, a feat that was eased by its fuselage keeping the same dimensions across its length.
[Norris and Wagner 1999, p. 17.] In April 1965, the company announced belated fuselage stretches for the DC-8 with three new models known as the ''Super Sixties''. The DC-8 program had been in danger of closing with fewer than 300 aircraft sold, but the Super Sixties brought fresh life to it. By the time production of the DC-8 ceased in 1972, 262 of the Super Sixties had been completed, almost half of all models produced. With the ability to seat 269 passengers, the DC-8 Series 61 and 63 had the largest passenger-carrying capacity available. That remained so until the

expressed concern about the noise to be expected from the then still-unbuilt DC-8-61, and operators had to agree to operate it from New York at lower weights to reduce noise. By the early 1970s, legislation for aircraft noise standards was being introduced in many countries, and the 60 Series DC-8s were particularly at risk of being banned from major airports.
In the early 1970s, several airlines approached McDonnell Douglas with requests for noise reduction modifications to their DC-8s. While third parties had developed aftermarket
hushkits, there was initially no meaningful action taken by Douglas to fulfil these requests and effectively enable the DC-8 to remain in service. Finally, in 1975,

began discussions with major airlines to fit the new and vastly-quieter Franco-American
CFM56 engine to both DC-8s and 707s. MDC remained reluctant but eventually came on board in the late 1970s and helped develop the Series 70.
The Super Seventies proved to be a great success, being roughly 70% quieter than the 60 Series and, at the time of their introduction, the world's quietest four-engined airliner. As well as being quieter and more powerful, the CFM56 was up to 23% more fuel-efficient than the JT3D, which reduced operating costs and extended the range.
The largest single customer for the Series 70 was United, converting 29 of its Series 61 airliners at a reported cost of $400 million.

Of the 556 DC-8s made, around 200 were still in commercial service in 2002, including about 25 50-Series, 82 of the stretched 60-Series, and 96 out of the 110 re-engined 70-Series. Most of the surviving DC-8s are now used as freighters. In May 2009, 97 DC-8s were in service following
UPS's decision to retire its remaining fleet of 44. In January 2013, an estimated 36 DC-8s were in use worldwide. As a result of aging, increasing operating costs and strict noise and emissions regulations, the number of active DC-8s continues to decline, with the youngest airframes having exceeded 50 years of age in 2022.

Pratt & Whitney JT3C-6 turbojets with water injection. First Series 10 DC-8 flew on 30 May 1958.
The initial DC-8-11 model had the original wingtips used on the prototype, and all remaining DC-8 Series 10 aircraft were upgraded to DC-8-12 standard. The DC-8-12 featured new low-drag wingtips and
leading-edge slots, 80 inches long between the engines on each wing and 34 inches long inboard of the inner engines. These unique devices were covered by doors on the upper and lower wing surfaces that opened for low-speed flight and closed for cruise. The maximum weight increased from . This model was originally named "DC-8A" until the series 30 was introduced.
[Norris and Guy 1999, .] 30 DC-8-10s were built: 23 for United and six for Delta, plus the prototype. By the mid-sixties, United had converted 16 of its 21 surviving aircraft to DC-8-20 standard and the other five to -50s. Delta converted its six to DC-8-50s. The prototype was itself also converted to a DC-8-50.

Pratt & Whitney JT4A-3 turbojets
(without water injection) allowed a weight increase to . 33 DC-8-20s were built plus 16 converted DC-8-10s.
This model was originally named "DC-8B" but was renamed when the Series 30 was introduced.
The first Series 20 DC-8 flew on 29 November 1958 and received FAA certification on 19 January 1960.
Series 30

For intercontinental routes, the three Series 30 variants combined JT4A engines with a one-third increase in fuel capacity and strengthened fuselage and landing gear.
The DC-8-31 was certified in March 1960 with 16,800 lb (75.2 kN) JT4A-9 engines for maximum takeoff weight. The DC-8-32 was similar but allowed weight. The DC-8-33 of November 1960 substituted 17,500 lb (78.4 kN) JT4A-11 turbojets, a modification to the flap linkage to allow a 1.5° setting for more efficient cruise, stronger landing gear, and maximum weight. Many -31 and -32 DC-8s were upgraded to this standard. A total of 57 DC-8-30s were produced (five of which were later upgraded to DC-8-50 standard).
The Series 30 DC-8 first flew on 21 February 1959 and received FAA certification on 1 February 1960.

turbofan was due in early 1961. The DC-8-41 and DC-8-42 had weights of respectively, the DC-8-43 had the 1.5° flap setting of the -33 and introduced a 4% leading-edge wing extension to reduce drag and increase fuel capacity slightly – the new wing improved range by 8%, lifting capacity by 6,600 lb (3 metric tons), and cruising speed by better than . It was used on all later DC-8s. The first DC-8-40 was delivered in 1960; 32 were built (of which three were eventually converted to DC-8-50s).
The Series 40 DC-8 first flew on 23 July 1959 and received FAA certification on 24 March 1960.
Series 50
The definitive short-fuselage DC-8 came with the same engine that powered the vast majority of 707s, the
JT3D. Twenty earlier DC-8s were converted to this standard. All but the -55 were certified in 1961. The DC-8-51, DC-8-52 and DC-8-53 all had 17,000 lb (76.1 kN) JT3D-1 or 18,000 lb (80.6 kN) JT3D-3B engines, varying mainly in their weights: , and respectively. The DC-8-55 arrived in June 1964, retaining the JT3D-3B engines but with strengthened structure from the freighter versions and maximum weight. 142 DC-8-50s were built plus the 20 converted from Series 10/30/40.
The Series 50 first flew on 20 December 1960 and received FAA certification on 1 May 1961.
* DC-8 Jet Trader: Douglas approved the development of freighter versions of the DC-8 in May 1961, based on the Series 50. An original plan to fit a fixed bulkhead separating the forward of the cabin for freight, leaving the rear cabin for 54 passenger seats was soon replaced by a more practical one to use a movable bulkhead and allow anywhere between 25 and 114 seats with the remainder set aside for cargo. A large cargo door was fitted into the forward fuselage, the cabin floor was reinforced and the rear pressure bulkhead was moved by nearly to make more space. Airlines could order a windowless cabin but only United did, ordering 15 in 1964. The DC-8F-54 had a maximum takeoff weight of and the DC-8F-55 . Both used 18,000 lb (80.6 kN) JT3D-3B powerplants. 62 aircraft built (plus one converted from a standard DC-8-50 and two of the three converted DC-8-40s).

Super 60 Series

* DC-8 Series 61: The "Super DC-8" Series 61 was designed for high capacity and medium range. It had the same wings, engines and pylons as the -55, and sacrificed range to gain capacity. Having decided to stretch the DC-8, Douglas inserted a plug in the forward fuselage and a plug aft, taking overall length to . The added length required strengthening of the structure, but the basic DC-8 design already had sufficient ground clearance to permit the one-third increase in cabin size without requiring longer landing gear.
[ The variant first flew on March 14, 1966, and was certified on September 2, 1966, at a maximum weight of .] Deliveries began in January 1967 and it entered service with United Airlines

in February 1967. It typically carried 180–220 passengers in mixed-class configuration, or 259 in high-density configuration.[ A cargo door equipped DC-8-61CF was also available. 78 -61s and 10 -61CFs were built.][
* DC-8 Series 62: The long-range Series 62 followed in April 1967. It had a more modest stretch, two plugs fore and aft of the wing taking overall length to , and a number of modifications to provide greater range. wingtip extensions reduced drag and added fuel capacity, and Douglas redesigned the engine pods, extending the pylons and substituting new shorter and neater nacelles, all in the cause of drag reduction. The 18,000 lb JT3D-3B was retained but the engine pylons were redesigned to eliminate their protrusion above the wing and make them sweep forward more sharply, so that the engines were some further forward. The engine pods were also modified with a reduction in diameter and the elimination of the and bypass duct. The changes all improved the aircraft's aerodynamic efficiency. The DC-8 Series 62 is slightly heavier than the or at , and is able to seat up to 189 passengers. The had a range with full payload of about ; roughly the same as the , but with 40 extra passengers.

, which produced of thrust. The conversions also includes new nacelles and pylons built by Grumman Aerospace. Maximum takeoff weights remained the same, but there was a slight reduction in payload because of the heavier engines. Modifications to create the -71 was more involved because the -61 did not have the improved wings and relocated engines of the -62 and -63.
All three models were certified in 1982 and a total of 110 60-series Super DC-8s were converted by the time the program ended in 1988. DC-8 series 70 conversions were overseen by Cammacorp with CFMI, McDonnell Douglas, and Grumman Aerospace as partners. Cammacorp was disbanded after the last aircraft was converted.
