The Boeing 797: Is the “Middle of the Market” Dream Finally Taking Flight?
Over 50 airlines signaled they wanted it. Boeing spent nearly a decade designing it. Yet, the Boeing 797, or New Midsize Airplane (NMA) as it was often called, remains grounded as a concept. But the forces that initially sparked its development – a gap between the 737 and 787, and the need for efficient transcontinental and thinner long-haul routes – haven’t disappeared. In fact, they’re intensifying. The question isn’t if Boeing will address this market, but when, and what form its solution will take.
The Promise of the 797: Filling a Critical Gap
The original vision for the Boeing 797 was compelling. Positioned to carry 220-270 passengers over 4,500-5,000 nautical miles, it aimed to bridge the gap between the narrow-body economics of the 737 MAX and the long-range capabilities of the 787 Dreamliner. A twin-aisle cabin promised faster boarding and a more comfortable passenger experience, crucial for attracting premium travelers on these routes. Early designs incorporated advanced technologies from the 777 and 787, including composite materials and improved aerodynamics, signaling a commitment to fuel efficiency and reduced operating costs.
Airlines saw the potential immediately. The 797 offered a pathway to open new routes that were too long for the 737 MAX but didn’t justify the capacity of a 787. Delta, United, Qantas, and Emirates were among the over 50 carriers expressing interest, recognizing the aircraft’s potential to unlock new revenue streams and optimize network efficiency.
Why the Project Stalled: A Perfect Storm of Challenges
Despite the initial enthusiasm, the 797 program faced a series of setbacks. The 2018 and 2019 737 MAX crashes forced Boeing to divert all available resources to address the crisis, effectively halting progress on the NMA. Simultaneously, delays in the 777X program and increasing production demands further strained the company’s capacity, making a clean-sheet aircraft program seem unfeasible.
However, the biggest hurdle proved to be engine technology. The 797 required a new engine in the 45,000–50,000 pound thrust class – a sweet spot between narrow-body and wide-body powerplants. While Rolls-Royce, Pratt & Whitney, and CFM International initially showed interest, none could deliver a viable option within Boeing’s timeframe. Rolls-Royce’s withdrawal in 2019 with its UltraFan program was a particularly significant blow, as it highlighted the technological challenges and the associated economic risks.
Adding to the pressure, Airbus launched the A321XLR in 2019. This long-range narrow-body aircraft, capable of flying nearly 4,700 nautical miles, entered service far sooner than the 797 could have, effectively capturing a significant portion of the “middle of the market” Boeing had targeted. Airlines like United, American, and JetBlue quickly placed substantial orders, further diminishing the potential for the 797.
The Future of Boeing’s Midsize Ambitions: A Slow Burn
As of late 2024, the Boeing 797 remains a concept, but the story isn’t over. Boeing CEO David Calhoun has repeatedly indicated continued interest, emphasizing the need for next-generation turbofan technology and advanced digital design tools. The company is leveraging lessons learned from its T-7 trainer jet program, focusing on digital development and maintenance-friendly design – features that could significantly influence a future 797.
A recent labor agreement with the International Association of Machinists and Aerospace Workers, committing to build a “next new airplane” in Washington state, has reignited speculation. While not explicitly confirmed as the 797, the timing is suggestive. Industry analysts generally predict a launch no earlier than the early 2030s.
What Will the Next Generation Look Like?
The future 797 is likely to be a scaled-down version of the 787, incorporating extensive use of composite materials, a twin-aisle configuration, and potentially adjustable seating arrangements to maximize revenue potential. However, Boeing is likely to prioritize reliability and efficiency over revolutionary changes, given its recent history of setbacks. The focus will be on minimizing risk and delivering a product that meets a clear market need.
The development of new engine technologies is paramount. The industry is eagerly awaiting advancements in turbofan design that promise significant improvements in fuel efficiency and reduced emissions. NASA’s X-59 QueSST program, while focused on supersonic flight, is also driving innovation in engine technology that could benefit future aircraft designs.
Ultimately, the Boeing 797’s future hinges on Boeing’s ability to stabilize its production line, secure a suitable engine, and demonstrate a clear economic case for the aircraft. For now, it remains one of aviation’s most anticipated “what ifs,” a testament to the enduring demand for efficient and versatile midsize aircraft.
