Information About

Boeing Y1




Y1 is a Boeing Commercial Airplanes project to replace the 717 , 737 , and 757-200 product lines. The Y1 is also known as the '''737RS''' (for "Replacement Study.")

New technologies to be introduced include Composite Aerostructures and more fuel-efficient Turbofan engines. Y1 is part of Boeing's Yellowstone project. The family is believed to be comprised of three (or possibly four) models which will seat 120, 150 and 190. It will be an entirely new aircraft rather than a further 737 derivative and will use much of the systems, structural and design technology of the 787 .

Competition for the Y1 is projected to come from the Airbus NSR (for "New Short-Range aircraft.")
