The Boeing 747: Deciphering Its Model Number Significance

The Boeing 747, often affectionately known as the 'Queen of the Skies,' is a symbol of the golden age of commercial aviation. Yet, behind its iconic design lies a fascinating history of model numbering systems and strategic business decisions. This article delves into the origins and significance of the 747's model number, exploring how it fits into Boeing's broader commercial jet numbering system.

The Evolution of Boeing's Model Numbering System

After World War II, Boeing transitioned from being a primarily military aircraft company to diversifying into commercial aviation, missiles, and spacecraft. To manage this expansion, the engineering department developed a model numbering system. This system was designed to categorize different product areas more clearly. The blocks of 100 were assigned as follows:

300s and 400s for aircraft 500s for turbine engines 600s for rockets and missiles 700s for jet transport aircraft

Boeing's journey towards the 747 began with the development of the first large swept-wing jet, the B-47. This aircraft caught the attention of several airlines, particularly Pan American World Airways (Pan Am), which expressed interest in integrating it into their fleet as a commercial jet transport.

The Birth of the Boeing 747

As Boeing started considering the feasibility of converting the propeller-driven model 367 Stratotanker (KC-97) into a jet-powered tanker, the company initiated studies on improving this model. After several iterations, the 367-80 was selected and nicknamed the . Boeing decided to finance the development and construction of the Dash 80 prototype with its own funds.

Given that both the Dash 80 prototype and its future offspring would be jet transports, the model number system required a number in the 700s to identify the new planes. The marketing department made the decision to choose 747 for the commercial jet transport. This choice was not arbitrary but was influenced by previous decisions:

717: The model number 717 was assigned to the KC-135, a military transport aircraft. 720: Originally the 707-020, this model was rechristened to be more marketable to United Airlines, which had previously chosen the DC-8.

Since the naming of the initial 747, all Boeing commercial jets have been named in a sequential manner based on the 7-7 formula: 727, 737, 747, and so on, up to the latest Boeing commercial jet, the 7E7.

The Significance of the Boeing 747's Model Number

The 747's model number is not just a series of digits; it carries significant historical and strategic meaning. It represents Boeing's commitment to innovation, reliability, and its enduring vision for air travel. The choice to reserve numbers starting or ending in 7 for commercial jets reflects Boeing's strategic marketing vision and its desire to establish a legacy of excellence in the aviation industry.

Conclusion

The story of the Boeing 747's model number is a testament to the company's evolution and its ability to adapt to changing market demands while maintaining its position as a leader in aircraft design and manufacturing.
