The Cessna Citation CJ4 Gen2 represents the latest evolution of the CitationJet 525 series, introduced by Textron Aviation in 2021 as an upgrade to the original CJ4 platform. Building on a lineage that began with the CJ1 and CJ3, the CJ4 extended the fuselage and incorporated a supercritical wing for improved aerodynamics. The Gen2 variant enhances this foundation with significant cabin refinements, advanced avionics, and improved passenger amenities.
The CJ4 first flew in 2008 and entered service in 2010, while the Gen2 upgrade began deliveries in 2021. Classified as a light jet, the CJ4 Gen2 offers single-pilot capability and combines midsize comfort with light-jet operating economics. It is powered by two Williams International FJ44-4A turbofan engines, each producing 3,621 pounds of thrust, enabling a maximum cruise speed of 451 knots and a service ceiling of 45,000 feet. The aircraft achieves a maximum range of 2,165 nautical miles, making it suitable for nonstop missions such as Los Angeles to Atlanta or New York to Phoenix. Takeoff distance at maximum weight is approximately 3,410 feet, and the maximum takeoff weight is 17,110 pounds.
The cabin measures 17 ft 4 in in length, 58 in in width, and 57 in in height, providing 293 cu ft of volume. Typical business seating accommodates 8–10 passengers in a versatile layout featuring club seating, executive tables, and a forward refreshment center. Gen2 upgrades include CoolView skylights, wireless cabin management, USB charging ports, and an externally serviceable lavatory. Baggage capacity totals 1,040 pounds, ensuring ample storage for business or leisure travel.
For operators, the CJ4 Gen2 delivers a compelling mix of speed, range, and cabin comfort at competitive operating costs, making it a flagship choice in the light jet category. Its combination of advanced avionics and passenger-focused upgrades ensures strong appeal for corporate flight departments and owner-operators seeking efficiency without sacrificing luxury.
