GE Aerospace Catalyst clean-sheet advanced turboprop model intended for the Beechcraft Denali. GE places it in the 1,200–1,400-shp class and documents a 16:1 overall pressure ratio, up to 18% lower fuel burn and 10% higher cruise power versus same-class competitors, additive-manufactured parts, and FAA Part 33 certification in 2025. GE reports production ramp-up toward entry into service; current operational service is not established, so lifecycle remains development.
