The Cessna CitationJet/CJ/M2 series are light business jets built by Cessna and part of the Citation family. Launched in October 1989, the Model 525 first flight was on April 29, 1991, FAA certification was awarded on October 16, 1992, and first delivery happened on March 30, 1993. Powered by two Williams FJ44s, it uses the Citation II's forward fuselage with a new carry-through section, wing, and T-tail. The basic CitationJet model was updated into the 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. By June 2017, 2,000 of all variants have been delivered.
Development 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. 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. 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. 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. To better compete with newer jets, Cessna also wanted to eliminate the step in the center aisle where the spar passes through the cabin.
Cessna launched the $2.4 million (equivalent to $4.95 million in 2019) model 525 CitationJet at the October 1989 NBAA convention in Atlanta, estimating a demand for 1,000 aircraft over ten years. Succeeding the 700 original Citation Is produced since 1972, first flight was scheduled for spring 1991, FAA certification in October 1992 and deliveries by the end of the year.
Its first flight was on April 29, 1991, FAA certification was awarded on October 16, 1992, and first delivery happened on March 30, 1993. The aircraft met its initial design goal: its normal cruise speed was 29 kn (33 mph; 54 km/h) faster than that of the Citation I, and it outperformed that aircraft in all other significant metrics except maximum payload and approach noise, despite having 600 lbf (2.7 kN) less total engine thrust. Twenty years after its first flight, 1,450 CJs had been produced. As of June 2017, 2,000 of all variants have been delivered with five million hours flown.
The jet uses the Citation II's forward fuselage, a new carry-through section, a new laminar flow, supercritical wing developed with NASA and Boeing, and a T-tail. Powered by two 1,900 lbf (8.5 kN) Williams FJ44s, the 10,000 lb (4,500 kg) aircraft has a trailing link undercarriage for smooth landings and can be flown by a single pilot. Range is 1,500 nmi (2,800 km) with four passengers and it can cruise at 437 kn (503 mph; 809 km/h).
The CitationJet retains the 58 in (147 cm) inside diameter, circular cross-section fuselage of the original 1971 Citation 500, a semi-monocoque construction of conventional aluminum alloys assembled with rivets, fasteners and adhesive bonding. To reduce interference drag, a large fairing encases the low wing center section, and the engines are mounted high on the tail. Composite materials save weight in non-load-bearing components including fairings and the nose radome. The cockpit features EFIS avionics; fuselage length is reduced 11 inches (27 cm) compared to the Citation I, and cabin length is reduced by 1 ft 6 in (46 cm), but with a lowered center aisle for increased cabin height. The cockpit side windows are slightly smaller than those on earlier Citations to lessen interior temperature differences between the cockpit and the main cabin.
Wing structure is a conventional ladder with chord-wise ribs over front and rear spars, and an aft sub spar to support the landing gear. The NASA high-speed 0213 airfoil sustains natural laminar flow over 30% of the upper surface for 10-15% better lift-to-drag ratio than the larger NACA 23000-series wing of the Citation 500. To maintain the wing's laminar-flow qualities and reduce weight, icing protection is provided by ducted bleed air rather than the deicing boots or fluid deicing systems used on earlier Citations.
Its FJ44 engine has a 16:1 overall pressure ratio and a 2.58:1 bypass ratio. Early CitationJet models have a novel design feature to reduce weight: rather than conventional thrust reversers, the aircraft are equipped with thrust attenuator paddles that pivot from the rear fuselage, similar to those used on the Cessna T-37 Tweet military trainer.
- Model 525 serial numbers 0001 to 0359, powered by Williams FJ44-1A turbofans, are marketed as the CitationJet.
- CitationJet CJ1
- Model 525 serial numbers 0360 to 0599 are marketed as the CitationJet CJ1 and are powered by the same Williams FJ44-1A. It was improved with a Pro Line 21 avionics suite, and a moderate increase in maximum takeoff weight.
- CitationJet CJ1+
- Model 525 serial number 0600 and higher are marketed as CitationJet CJ1+ and are powered by Williams FJ44-1AP turbofans. With the same airframe, it has Pro Line 21 avionics package and FADEC engine control. It was certified in 2005.
- The GE Honda HF120 engine was announced as a retrofit option for the CJ/CJ1/CJ1+ in 2014.
- Citation M2
- Model 525 marketed as Cessna Citation M2 are powered by improved FJ44-1AP-21 turbofans offering 10 to 15% more cruise thrust and up to 5% more hot-and-high thrust, and are equipped with modern Garmin G3000 avionics replacing Rockwell Collins Pro Line 21. Launched in September 2011, it is based on the then out-of-production CJ1 variant and features a new cabin layout and a more efficient FJ44 version. The initial M2 prototype first flew on 9 March 2012, it was not a conforming airframe but was testing the Garmin G3000 avionics and Williams FJ44-1AP-21 turbofans while one another aircraft was expected to join the certification program in May 2012 to be used for aerodynamics testing. Compared to the CJ1+, it climbs more quickly, offers a more comfortable cabin and is faster by 22 kn (41 km/h) at FL 410. The wing is 4 in (10 cm) wider due to small winglets with little effect. The FJ44-1AP-21 TBO can reach 5,000 h and both burns 740 lb (340 kg) per hour at 392 kn (726 km/h) TAS, FL 400, ISA+3C conditions and at a weight of 9,646 lb (4,375 kg). At high-speed cruise, it can fly one pilot and four passengers over 1,150 nmi (2,130 km) in 2 h 49 min. It climbs to FL 410 in 24 min, 27% faster than its closest competitor, where it is 53 kn (98 km/h) faster than the Embraer Phenom 100E. With 150 produced since introduction in 2013, it became Cessna's entry-level jet after the Citation Mustang production stopped in May 2017. The 250th M2 was delivered on June 15, 2020.
The ICAO aircraft type designator for the CJ2 models is C25A.

The ICAO aircraft type designator for the CJ3 models is C25B.
- CitationJet CJ3
- Model 525B are marketed as the CitationJet CJ3 are a further stretch of the CJ2 powered by Williams FJ44-3A turbofans. Unveiled at the September 2002 National Business Aviation Association convention, it first flew on April 17, 2003, was FAA certified in October 2004 and deliveries began in December of that year. The cockpit with Rockwell Collins avionics is designed for single-pilot operation but can accommodate two crew members. Its customizable cabin typically has six club seats in a center-style configuration with an accessible in flight baggage compartment and external baggage access.
- Between its production debut in late 2004 and spring 2018, 500 of CJ3s and CJ3+s have been delivered, 2004-2009 models are sold for $3.5 million and $5.0-5.5 million for 2009-2014 models.
- CJ3 can cruise at its Mach 0.737 (423 kn; 783 km/h) MMo at FL450 over 1,900 nmi (3,500 km) with four passengers, or more than 2,000 nmi (3,700 km) at a slower speed, exceeding Textron predictions.
- Hourly, CJ3 burns 165 US gal (620 l) its engine maintenance cost $313.60, its parts $251.72 and labor cost is $298.
