Yellowstone projects

Yellowstone is divided into three projects:
  • Boeing Y1, to replace the Boeing 737
    Boeing 737
    The Boeing 737 is a short- to medium-range, twin-engine narrow-body jet airliner. Originally developed as a shorter, lower-cost twin-engine airliner derived from Boeing's 707 and 727, the 737 has developed into a family of nine passenger models with a capacity of 85 to 215 passengers...

     product line. Y1 covers the 100- to 200-passenger market, and is expected to be the second Yellowstone Project aircraft to be developed. Boeing submitted a patent application In November 2009, that was released to the public in August 2010, that envisions an elliptical composite fuselage, and likely signals the company's planning for the 737 successor. In early 2011, Boeing outlined plans for a 737 replacement that would arrive in 2020. But the development of the 737 replacement has pushed back with the decision to launch the 737 MAX
    Boeing 737 MAX
    The Boeing 737 MAX is a new family of aircraft being developed by Boeing Commercial Airplanes to replace the Boeing 737 Next Generation family. The primary change will be the use of the larger and more efficient CFM International LEAP-1B engines. The airframe is to receive some modifications as...
