To offer increased speed with reduced purchase and operating costs, Cessna engineers realized that a new, lighter airframe design would be needed, using less expensive and lower-thrust engines. However, that aircraft had been stigmatized for its slower cruise speed than its competitors, which had progressively been addressed in the Citation S/II and Bravo and the Citation V, Ultra and Encore, but at the cost of operating economy.

Cessna believed that a substantial market still existed for a light 4-5 passenger jet with low operating costs, docile flying qualities, and the ability to operate from short runways usable by light piston twins, a formula that had made the Citation I successful. Like several other members of the Citation family, the CitationJets are certified for operations with a single pilotĭevelopment of the CitationJet was prompted by the 1985 discontinuation of the Citation I, a reaction to the increasing price of its Pratt & Whitney JT15D-1 engines, which rendered it uncompetitive with its larger straight wing Citation stablemates. By June 2017, 2,000 of all variants have been delivered. The basic CitationJet model was updated into the CJ1/CJ1+/M2 variants additionally, CJ1 was stretched into the CJ2/CJ2+ delivered from 2000 to 2016, then further into the CJ3/CJ3+ delivered from December 2004 and finally into the CJ4 delivered since 2010. Powered by two Williams FJ44s, it uses the Citation II's forward fuselage with a new carry-through section, wing, and T-tail. Launched in October 1989, the Model 525 first flight was on April 29, 1991, Federal Aviation Administration certification was awarded on October 16, 1992, and first delivery happened on March 30, 1993.
