Sept. 4, 2025, © Leeham News: The coming decade is likely to see announcements of new airplanes from Airbus and Boeing. If Embraer decides to move up into the mainline sector, a new airplane from the Brazilian manufacturer should also be announced in the next few years.

This means the clock is ticking toward program launches anywhere between 2027 and 2030, depending on progress from GE Aerospace, Pratt & Whitney and Rolls-Royce in developing new engines.

For the airframe manufacturers, there are important steps before a new program can be launched. One is how the aircraft shall be developed. We wrote about it in our series “What’s the Next New Aircraft?”. But equally important is, how shall the next new aircraft be produced? It’s what this seven part series is about.

Since June, LNA has published a series of articles about new airplanes, new technologies, new design and new production processes that must be sorted before any of the OEMs move forward. Across the seven parts of this series, we identify flaws and challenges at both Airbus and Boeing, with lessons to be learned as both airframers reshape their approach for future manufacturing.
