The Citation V, Citation Ultra and Ultra Encore are the largest straight wing members of Cessna's highly successful Citation family. Cessna publicly announced it was developing a stretched development of the Citation II at the annual NBAA convention in New Orleans in 1987. Earlier in August that year the first engineering prototype Model 560 Citation V had successfully completed the type's maiden flight. A preproduction prototype flew in early 1986, while US certification was granted on December 9 1988. Deliveries began the following April.
