Background
April 6, 2026, © Leeham News: Depending on what starting point you want to choose, it will be about 30 years between brand new, clean sheet airplane designs at The Boeing Co.
Boeing announced its 787 program in December 2003, with a formal launch the following spring. The entry-into-service goal for the 787 was May 2008. Boeing planned to design a replacement for the aging 737 platform after the 787 entered service. A new design for replacing the 777 was supposed to come after that.
The 787’s EIS date came and went as design and production problems added up to 3 ½ years of delay.
With cost overruns, deferred production, and deferred tooling costs totaling more than $50bn, plus several billion more dollars written off for research and development and abnormal production costs, the 787 still has more than $14bn in deferred costs to recover.
Delays and cost overruns hurt the 747-8 program. The 2019 21-month grounding of the 737 MAX resulted in billions more in charges. The January 2024 door plug blowout on a new Alaska Airlines 737-9 hurt recovery. Scrutiny by the Federal Aviation Administration (FAA) continues to this day. Production rates for the 737 and 787 are well below those that predate the MAX grounding. Certification of the 737-7, 737-10, and 777X remains a hope, not a reality, so far.
A plethora of losses, charges, and delays in defense and space programs added to the losses. Boeing’s long-term debt in 2018, its last normal year, was over $10bn. Today, it’s over $54bn, with big repayments coming soon.
Boeing’s next new airplane program remains years away.
What will Boeing’s next new airplane be? We have a pretty good idea. A new series beginning Thursday explores this question. Credit: Leeham News.
