Operational Context

Cessna Citation Hemisphere — proposed long-range business jet

The Hemisphere project was introduced in the mid-2010s as a clean-sheet large-cabin Citation design. It was planned to use advanced turbofan engines and composite structures to enhance efficiency. Development progressed through early design stages before engine supplier challenges emerged.

Projected cruise speed was approximately 450 knots (830 km/h), with a maximum takeoff weight near 40,000 pounds (18,140 kg). Range goals were around 4,500 nautical miles (8,330 km). The cabin was designed for up to 12 passengers in executive configuration.

Following delays and market reassessment, Textron Aviation canceled the program in the late 2010s. Although it did not reach production, the Hemisphere illustrated evolving expectations in the super-midsize business jet segment. The project remains part of Citation development history.
