History: Design of the
Constellation began in 1939, when Pan American Airways and Transcontinental & Western
Air (later TWA) issued a design requirement for a 40-passenger airliner for their domestic
routes. Production of the resulting L-49 by Lockheed began, but
was interrupted by the outbreak of World War II. The US Army Air Corps commandeered at
least 22 of the aircraft off the assembly line, designated them C-69s,
and used them as transports.
After the war, when civil production resumed under several
designations, the military ordered a new, longer-range version called the C-121.
In the years that followed, no fewer than 20 variants were developed for military use,
including the VC-121B (Presidential/VIP transport); the PO-1W
(US Navy airborne early warning platform); the R7V1/C-121J
(Polar ice-pack reconnaissance); VW-2/EC-121K Warning Star
(Airborne Early Warning); WV-2Q/EC-121L (Electronic
Countermeasures); WV-3/WQC-121N (Weather reconnaissance); RC-121D/EC-121D
(USAF version of US Navy WV-2 with wingtip tanks and different interior
layout); JC-121C (Avionics and systems research); and numerous
Civilian variants included the 48-81 passenger L-649,
which was replaced in 1947 by the longer-range L-749, and then
by the 109-passenger L-1049 Super Constellation in 1949. The
last of the "Connies" was the L-1649A Starliner, with
a completely new wing and greater fuel capacity and range. Production of all
Constellations ended in the late 1950s, but the type lived on for decades as an airliner
and freighter in many smaller countries.
The Constellation contributed to its national defense in so
many ways that it is difficult to fully account the impact it had. The few remaining
airworthy examples are increasingly appreciated for their looks, performance and
