Lockheed L.1049 Constellation
A stretched version of the L.749, the L.1049 Super Constellation, was introduced in 1950. Gross weight was increased substantially when the fuselage was expanded by 18.4 feet and 3,250-hp Wright engines were fitted. The stretched “Connie” held up to 91 passengers; with tip tanks, range was increased to 5,840 miles.
The first prototype Super Constellation (a conversion of the original C-69 prototype) flew for the first time on 13 October 1950. First in commercial service (on 15 December 1951) was one owned by Eastern Air Lines. This version could accommodate 71 first-class or 95 coach-class passengers (14 delivered to Eastern and ten to TWA during 1951-52).
The L.1049C model had structural modifications to allow a gross weight of 150,000 pounds, provided that more powerful engines were available. Lockheed built 286 Super Connies.
L-1049 Super Constellation were in use by both the USAF and US Navy under a variety of C-121C and R7V-1 designations respectively.
