Lockheed Constellation

Initial studies Lockheed had been working on the L-044 Excalibur, a four-engined, pressurized airliner, since 1937. In 1939, Transcontinental and Western Airlines (TWA), at the instigation of major stockholder Howard Hughes, requested a 40-passenger transcontinental airliner with a range of —well beyond the capabilities of the Excalibur design. TWA's requirements led to the L-049 Constellation, designed by Lockheed engineers, including Kelly Johnson and Hall Hibbard. Willis Hawkins, another Lockheed engineer, maintains that the Excalibur program was purely a cover for the Constellation. Development of the Constellation The Constellation's wing design was close to that of the Lockheed P-38 Lightning, differing mostly in size. The triple tail allowed the aircraft to fit into existing hangars, while features included hydraulically boosted controls and a deicing system used on wing and tail leading edges. The aircraft had a maximum speed over , faster than that of a Japanese Zero fighter, a cruise speed of , and a service ceiling of . According to Anthony Sampson in Empires of the Sky, Lockheed may have undertaken the intricate design, but Hughes's intercession in the design process drove the concept, shape, capabilities, appearance, and ethos. These rumors were discredited by Johnson. Howard Hughes and Jack Frye confirmed that the rumors were false in a letter dated November 1941. ==Operational history==

World War II With the onset of World War II, the TWA aircraft entering production were converted to an order for C-69 Constellation military transport aircraft, with 202 aircraft intended for the United States Army Air Forces (USAAF). The first prototype (civil registration NX25600) flew on January 9, 1943, a short ferry hop from Burbank to Muroc Field for testing. The L-1649A holds the record for the longest-duration, nonstop passenger flight aboard a piston-powered airliner. On TWA's first London-to-San Francisco flight on October 1–2, 1957, the aircraft stayed aloft for 23 hours and 19 minutes (about at ). Obsolescence Canada at Manchester Airport in 1966 Jet airliners such as the de Havilland Comet, Boeing 707, Douglas DC-8, Convair 880, and Sud Aviation Caravelle rendered the Constellation obsolete. The first routes lost to jets were the long overseas routes, but Constellations continued to fly domestic routes. The last scheduled passenger flight of a Constellation in the contiguous United States was made by a TWA L749 on May 11, 1967, from Philadelphia to Kansas City, Missouri; the last scheduled passenger flight in North America was by Western Airlines' N86525 in Alaska - Anchorage to Yakutat to Juneau on 26 November 1968. Constellations carried freight in later years, and were used on backup sections of Eastern Airlines' shuttle service between New York, Washington, DC, and Boston until 1968. Propeller airliners were used on overnight freight runs into the 1990s, as their low speed was not an impediment. An Eastern Air Lines Connie holds the record for a New York–to–Washington, DC, flight from takeoff to touchdown in just over 30 minutes. The record was set prior to speed restrictions by the Federal Aviation Administration below . One of the reasons for the elegance of the aircraft was the dolphin-shaped fuselage, a continuously variable profile with no two bulkheads the same shape and a skin formed into compound curves, which was expensive to build. Manufacturers have since favored tube-shaped fuselages in airliner designs, as the cylindrical cross-section design is more resistant to pressurization changes and less expensive to build. After ending Constellation production, Lockheed chose not to develop a first-generation jetliner, sticking to its military business and production of the turboprop Lockheed L-188 Electra. Lockheed did not build a large passenger aircraft again until its L-1011 Tristar debuted in 1972. While a technological marvel, the L-1011 was a commercial failure, and Lockheed left the commercial airliner business permanently in 1983. ==Variants==

, Rhodesia (now Zimbabwe) in 1975, used as a flying club headquarters (L-1249) in flight: The L-1249 used Pratt & Whitney T34 turboprop engines in place of the Wright R-3350 radials. The initial military versions carried the Lockheed designation of L-049; as World War II came to a close, some were completed as civilian L-049 Constellations followed by the L-149 (L-049 modified to carry more fuel tanks). The first purpose-built passenger Constellations were the more powerful L-649 and L-749 (which had more fuel in the outer wings), L-849 (an unbuilt model to use the R-3350 turbo-compound engines adopted for the L-1049 ), L-949 (an unbuilt, high-density seating-cum-freighter type, what would come to be called a "combi aircraft"). ==Operators==

After TWA's initial order was filled following World War II, customers rapidly accumulated, with over 800 aircraft built. In military service, the U.S. Navy and Air Force operated the EC-121 Warning Star variant until 1978, nearly 40 years after work on the L-049 began. Cubana de Aviación was the first airline in Latin America to operate Super Constellations. ==Surviving aircraft==

It was delivered to Air France on November 2, 1953, and was upgraded to a L-1049 G in 1956, serving until August 8, 1967, having totaled 24,284 hours under Air France's colors. After retirement, it was sent to Spain, to be registered EC-BEN, briefly flying humanitarian and medevac missions in Biafra. Aero Fret bought it in 1968, brought it back home to France, registered it as F-BRAD, and operated it on cargo hauls until 1974. When the Constellation landed in Nantes one last time to be scrapped, it was ultimately saved by Mr. Gaborit, who revamped it somewhat by his own modest means to finally park it near the terminal, accessible to visitors for a few years, until the Chamber of Commerce and Industry of the Nantes-Atlantique Airport bought it, to contract the Amicale du Super Constellation to undergo a complete restoration of the aircraft. • HI-542CT City of Miami – parked on an unused runway at the Rafael Hernández Airport in Aguadilla, Puerto Rico. It was struck by a runaway DC-4 on February 3, 1992, resulting in damage to the right wing and main spar. • N6937C Star of America – to airworthiness by the National Airline History Museum in Kansas City, Missouri. This aircraft was originally built in 1957, stored for several years, and then delivered to cargo carrier Slick Airways. It was restored in 1986 by the Save-a-Connie, Inc. organization, later renamed as the National Airline History Museum. It was originally painted in red and white with Save-a-Connie, but was later repainted in the 1950s livery of TWA to resemble its original Star of America Constellation. The aircraft appeared at New York's John F. Kennedy International Airport at the original TWA terminal designed by Eero Saarinen to commemorate the 75th anniversary of the airline with the paint scheme donated by TWA in Kansas City for the occasion. The Star of America has appeared at many airshows and was even used in The Aviator, the 2004 film depicting the life of TWA's one-time owner Howard Hughes, the man often credited with helping design and develop the original Constellation series. ;;L-1649 Starliner • N7316C – returned to airworthiness by Lufthansa Technik North America in Auburn, Maine. This aircraft was purchased at auction in 2007, along with C/N 1038, by the Deutsche Lufthansa Berlin Foundation. Lufthansa has built a hangar at the airport, which will allow the aircraft to be restored indoors. Lufthansa announced in March 2018 that it will be transported back to Germany and further restoration decisions will be made after it arrives. As of the end of 2019 the plan is to restore the aircraft for static display in a museum. According to reports from the US, the aircraft was dismantled (as apparently was the Ju-52 D-AQUI) without the requisite documentation that would have allowed the return-to-flight work to continue. • N8083H – This aircraft was purchased at auction in 2007, along with C/N 1018, by the Deutsche Lufthansa Berlin Foundation, and stripped of all usable spares to support the restoration of C/N 1018. The aircraft was subsequently sold and transported to JFK International Airport to become a cocktail bar in the TWA Hotel, a retro-aviation themed hotel built on the former TWA Flight Center. Military ;Airworthy ;;C-121C • S/N 54-0156 – Flies with the Super Constellation Flyers Association out of Basel, as the Breitling Super Constellation.

This Constellation is one of three flying in the world. , 2004 • S/N 54-0157 – Flies with the Historical Aircraft Restoration Society (HARS) out of Shellharbour Airport near Wollongong, Australia. Following its restoration, it was painted in pseudo-Qantas livery, including the Qantas logo on the tail, (with the usual Qantas lettering along the fuselage and on the wing-end fuel tanks replaced with the word "CONNIE") and registered as VH-EAG. This Constellation is one of the other of three flying in the world. • S/N 48-0613 Bataan – Restored to airworthiness by Lewis Air Legends in San Antonio, Texas. This aircraft was used as a personal transport by General Douglas MacArthur during the Korean War, and later by other Army general officers until 1966, when it was transferred to NASA. Following its permanent retirement in 1970, it was placed on display at a museum at Fort Rucker near Daleville, Alabama. It was acquired by the Planes of Fame Air Museum at Chino, California, in 1992, and overhauled into airworthy condition for a flight to Dothan, Alabama, where it received additional work. After a thorough restoration back to its original configuration with a "VIP interior", it was placed on display at the Planes of Fame secondary location in Valle, Arizona. Then, in 2015, it was sold to Lewis Air Legends, and prepped for a ferry flight to Chino, arriving there on January 14, 2016. On June 20, 2023, the Air Legends Foundation’s Lockheed VC-121A Constellation took off on its first post-restoration flight from Chino Airport. The aircraft flew to the 2023 EAA AirVenture Oshkosh in Oshkosh, Wisconsin. In July 2025, the aircraft completed a six year long custom executive VIP interior designed by Aerometal International, based in Aurora, Oregon. In late July, 2025, Bataan returned to visit EAA AirVenture Oshkosh in Oshkosh, Wisconsin. ;;On display • N8083H – L-1649A on display at the TWA Hotel at John F.
