# Cessna Citation family

The Cessna Citation is a family of business jets manufactured by Cessna that entered service in 1972. In the fifty years following the type's first flight in 1969, more than 7,500 Citations were delivered, forming the largest business jet fleet in the world. Deliveries reached 8,000 by 2022, while logging over 41 million flight hours.
The line started with the small Citation I prototype flying on September 15, 1969, and produced until 1985, developed into the 1978-2006 Citation II/Bravo, the 1989-2011 Citation V/Ultra/Encore and the CitationJet since 1993. The standup Citation III/VI/VII was delivered from 1983 to 2000; its fuselage was reused in the Citation X/X+ delivered from 1996 to 2018, the Sovereign from 2004 to 2021 and the Excel since 1998. The Mustang was a Very Light Jet delivered from 2006 to 2017 while the flat floor fuselage Latitude has been delivered since 2015 and the larger Longitude from 2019.
The aircraft are named after Citation, a champion American Thoroughbred racehorse who won the American Triple Crown.

### Hemisphere

Announced in November 2015, it was then expected to fly in 2019 but its development was suspended in April 2018 due to a delay in the development of its Safran Silvercrest engines. It was designed for Mach 0.9 and would have a 4,500 nautical miles (8,300 km) range.
