The next aircraft in the Cessna Citation family was the Cessna Model 550 Citation II, whose prototype was unveiled in September 1976 and made its maiden flight on January 31, 1977. Its design underwent substantial changes, including the installation of a wing with an increased span, a lengthened fuselage that expanded its capacity to 12 people, and the integration of more powerful JT15D-4 turbofan engines, each providing 11.12 kN of thrust, along with an increased fuel capacity.
Advanced Features and Variants
Citation II aircraft served in the Spanish Navy and the Venezuelan Air Force. These aircraft were also acquired by the Air Forces of Myanmar (Burma) and Turkey. The Model S550 Citation S/II, which took to the skies on February 14, 1984, featured a wing with a new profile and aerodynamic ‘saw-cuts’ on the leading edge, and was equipped with JT15D-4B turbofan engines.
The Evolution to Citation Bravo
A subsequent variant of the Citation II, featuring new Pratt & Whitney Canada PW530A engines with 12.23 kN of thrust each, improved avionics, and a new cabin interior borrowed from the Citation V Ultra, was named the Citation Bravo. The prototype for this version flew on April 25, 1995, with deliveries to customers commencing in June 1996.
