Lockheed Constellation World Class Icon in Aviation

The Lockheed Constellation, affectionately known as the “Connie,” stands as one of the most iconic aircraft in aviation history, and that’s no mean feat.

In 1939, the senior executives of Lockheed Corporation—President Robert Gross, Chief Engineer Hall Hibbard, and Chief Research Engineer Kelly Johnson—organized a crucial meeting with a very important potential client.

This individual, known for his substantial financial resources, had expressed interest not merely in purchasing a single aircraft or a small number, but an entire fleet.

The prospective client’s vision was ambitious: he sought Lockheed’s expertise to create a groundbreaking aircraft designed to comfortably transport 20 passengers and 6,000 pounds of cargo non-stop across the United States, heralding the dawn of coast-to-coast, uninterrupted commercial flight.

However, Lockheed’s team aimed to propose something even more extraordinary. They envisioned Lockheed’s inaugural large-scale transport aircraft, one that “would transport more passengers over greater distances at higher speeds than ever before, and economically enough to revolutionize the public’s perception of air travel as a viable alternative to trains, ships, and automobiles,” in Johnson’s words.

The Lockheed Model 1249, a turboprop-driven Super Constellation, was initially commissioned by the US Navy under the designation R7V-2. This aircraft emerged as the swiftest variant in the Constellation lineup, yet it was ultimately overshadowed as both turboprop and jet aircraft became the preferred choices among all stakeholders.

It would come to be celebrated as a timeless icon, epitomizing the elegance of propeller-driven aviation. But during that pivotal meeting in 1939 in Los Angeles, Lockheed’s immediate objective was to secure the commitment of that one crucial client – Howard Hughes.

Origins and Development

As mentioned above, the story of the Lockheed Constellation begins in the early 1939. The concept was born out of a request by Howard Hughes, the eccentric billionaire and a major shareholder of Trans World Airlines (TWA), who approached Lockheed to build a pressurized, long-range airliner that could outperform the existing models.

Hughes’ vision was to create an aircraft that would enable TWA to dominate transcontinental and transatlantic air travel.

Hughes envisioned an airliner that would transcend the existing standards of speed, range, and passenger comfort. His ambitions were aligned with the post-war foresight of air travel becoming a dominant mode of global transit, necessitating the development of an aircraft that could offer unprecedented transcontinental and transatlantic capabilities.

Lockheed, under the guidance of the visionary designer Clarence “Kelly” Johnson, who later became renowned for his work on aircraft like the SR-71 Blackbird, accepted the challenge.

This capability was complemented by the aircraft’s range and speed, allowing for non-stop transcontinental and transatlantic flights, which revolutionized commercial air travel.The aircraft’s initial versions were equipped with the Wright R-3350 Duplex-Cyclone radial engines, which were powerful but required careful management.

In the Constellation, Lockheed had crafted an aircraft that not only met Hughes’ demanding specifications but also pushed the boundaries of aeronautical engineering.

The Connie’s sleek, flowing lines and distinctive triple-tail were as much a function of its aerodynamic needs as they were of its aesthetic appeal.

New era for the Constellation

World War II played a pivotal role in the Constellation’s early life. Although designed for civilian use, the outbreak of the war saw the newly built aircraft being requisitioned by the U.S. military, where they were designated as C-69 transport planes.
