The initial military versions carried the Lockheed designation of L-049; as World War II came to a close, some were completed as civilian [[Lockheed L-049 Constellation|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 [[Lockheed L-649 Constellation|L-649]] and [[Lockheed L-749 Constellation|L-749]] (which had more fuel in the outer wings),<ref name="Stringfellow and Bowers">{{harvnb|Stringfellow|Bowers|1992}}</ref>{{Page needed|date=November 2010}} L-849 (an unbuilt model to use the [[Wright R-3350|R-3350]] [[Turbo-compound engine|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]]").<ref name="Stringfellow and Bowers" />

These were followed by the [[Lockheed L-1049 Super Constellation|L-1049 Super Constellation]] (with longer fuselage), L-1149 (proposal to use Allison turbine engines)<ref name="Stringfellow and Bowers" /> and [[Lockheed L-1249 Super Constellation|L-1249]] (similar to L-1149, built as R7V-2/YC-121F),<ref name="Stringfellow and Bowers" /> L-1449 (unbuilt proposal for L1049G, stretched {{convert|55|in|cm|abbr=on}}, with new wing and turbines)<ref name="Stringfellow and Bowers" /> and L-1549 (unbuilt project to stretch L-1449 {{convert|95|in|cm|abbr=on}}).<ref name="Stringfellow and Bowers" />

The final civilian variant was the [[Lockheed L-1649 Starliner|L-1649 Starliner]] (all new wing and L1049G fuselage).<ref name="Stringfellow and Bowers" />

Military versions included the [[Lockheed C-69 Constellation|C-69]] and [[Lockheed C-121 Constellation|C-121]] for the [[United States Army Air Forces|Army Air Forces]]/[[United States Air Force|Air Force]] and the R7O R7V-1 (L-1049B) [[Lockheed EC-121 Warning Star|EC-121]] WV-1 (L-749A) WV-2 (L-1049B) (widely known as the Willie Victor) and many variant EC-121 designations for the [[United States Navy|Navy]].<ref>Swanborough, Gordon and Peter M.
