The Lockheed L-1649 Starliner was the last model of the Lockheed Constellation
Lockheed Constellation
The Lockheed Constellation was a propeller-driven airliner powered by four 18-cylinder radial Wright R-3350 engines. It was built by Lockheed between 1943 and 1958 at its Burbank, California, USA, facility. A total of 856 aircraft were produced in numerous models, all distinguished by a...

 and high operating costs, though the T34 military version of the engine powered the Douglas C-133 freighter.

The Air-Britain book says the L-1449 would have been 55 inches longer than the L-1049 series with a maximum weight of 175,000 lb; The L-1549 replaced the 1449 in early 1955 with an additional 40-inch stretch and a takeoff weight of 187,500 lb, presumably still with the big PT2 turboprops.

But Rummel's book says Lockheed told TWA on 30 Sept 1954 the L-1449 would use the same fuselage as the 1049 series; Hughes Tool Co ordered 25 of them in December, though TWA estimated the L-1449 would lose money for them even with every seat occupied. When P&W dropped their engine Lockheed proposed an L-1549 with Allison turboprops, but TWA and Lockheed agreed on the piston-engine L-1649 instead and so amended the L-1449 contract. In April 1955 Lockheed told TWA they wanted to drop the 1649, but Hughes refused to agree.

Though the L-1449 and L-1549 were never built, all Constellations from 1954 onward were strengthened to take the thrust generated by the T34/PT-2 turboprops, which were fitted to several R7V-2 Constellations for the United States Navy

With the abandonment of the L-1549, Lockheed designed a less ambitious upgrade of the Constellation series as the L-1649A Starliner. The new design used the L-1049G fuselage, the new 150 ft (45.7 m) wing and four Wright R-3350

"Lockheeds claim that their new airliner, powered by four 3,400 h.p. Wright Turbo-Compounds, will be capable of carrying 58 passengers for 6500 miles at a cruising speed of over 350 m.p.h. and that it will fly from Paris to New York in nearly three hours less time than the DC-7C when carrying the same payload as its Douglas competitor." In January 1958 Pan American scheduled the DC-7C Orly to Idlewild in 14 hr 15 min; TWA scheduled the 1649 in 14 hr 50 min.

Operational history

The L-1649A prototype first flew on October 11, 1956 (The prototype (N1649) would remain the property of Lockheed until the early 1970s, when it was sold in Japan). Airline service began on June 1, 1957 on a Trans World Airlines

 (TWA) flight from New York to London and Frankfurt. TWA called their L-1649s "Jetstreams" and flew them on their longer domestic routes, along with flights from New York to Europe and beyond. In July 1958 TWA scheduled 60 flights each week from Europe to New York, of which 30 were L-1649s, including seven nonstops a week from Paris, five from London, four from Frankfurt, two each from Madrid, Lisbon and Geneva, one from Zurich and one from Rome. Three 1649s a week flew the Polar route Europe to California, sometimes nonstop.

707s replaced the last TWA transatlantic passenger L-1649 in October 1961; 707s and 880s displaced them from domestic scheduled flights in December 1962. In the early 1960s Lockheed converted twelve TWA L1649s to freighters that carried cargo across the Atlantic until 1964 and domestically until 1967.

Transatlantic flights lasted from August 1957 until September 1960 when the 707 took over. Starting in April 1958 Air France L-1649s flew Paris to Anchorage to Tokyo, but they never flew to the west coast of the United States. In summer 1959 they scheduled 22 nonstop L-1649s a week from Orly to Idlewild, four of which continued to Mexico City; two weekly L-1649s flew Orly to Montreal to Chicago Midway and back. The twice-weekly ORY-ANC-TYO flight was scheduled 30 hr 45 min, compared to 42 hr 20 min for the fastest 1049G via India (and 32 hr 00 min for BOAC's Comet from London to Tokyo via India).

The DC-7C ended up selling more airframes than the Starliner, which had greater range than its rival but was expensive ($3,000,000 USD) and entered service a year later. In the end only 44 Starliners were built (including the prototype) compared to 121 DC-7Cs from Douglas.
