13 декабря 2017г. журнал Flight International сообщил, что французская компания Dassault Aviation объявила о прекращении работы над бизнес-джетом Falcon 5Х. Такое решение было принято из-за разрыва контракта на поставку двигателей Silvercrest производства Safran Aircraft Engines, вызванного непрекращающимися проблемами с этой силовой установкой.

The Falcon 5X’s development has been delayed by development issues with the Snecma Silvercrest engines powering the aircraft.

The 5X is the second new Dassault Falcon to emerge within six months, following the unveiling of the ultra-long-range 8X last December.

Dassault announced on May 1, 2014 the joining of the main centre fuselage sections of the first Falcon 5X business jet at Biarritz in southwest France. The front (seen here) and rear sections will be added in June and the completed fuselage will be delivered to Merignac for final assembly. The Falcon 5X was revealed in October 2013 during the National Business Aviation Association Convention in Las Vegas. Ground tests are scheduled to start in the summer with the maiden flight due in the first half of 2015, certification in the last quarter of 2016 and service entry in mid-2017. Three aircraft will participate in the flight test programme.

The first Falcon 5X is due to fly in the second quarter of 2015.

Aircraft manufacturer, Dassault Aviation, has unveiled its new Falcon 6X long-range business jet during a closed-door ceremony held in the Charles Lindbergh Hall at its Bordeaux/Merignac plant in France. A traditional rollout could not be held as a result of COVID-19 restrictions, resulting in a virtual launch event that was held on December 8, 2020. The prototype, F-WAVE (c/n 03), is expected to make its maiden flight in the coming months after completing a ground test programme. Service entry for the Falcon 6X is expected to take place in 2022

Dassault increased its backlog of orders at the end of 2021, partly thanks to announcing new models. Flight testing of the Falcon 6X began in March 2021

Dassault test pilots Philippe Deleume and Philippe Rebourg flew Falcon 5X F-WFVX on maiden initial flight.

A third-generation version of Dassault’s EASy flight deck, which uses Honeywell's Primus Epic avionics, is designed to be highly interactive and intuitive to maximise pilots’ situational awareness.

Key flightdeck features are the FalconEye combined vision system and Honeywell Primus avionics.

The Falcon 6X is known for its luxurious cabin design

Dassault Aviation has won the International Yacht & Aviation Award for interior design for the cabin of the Falcon 6X. The cabin has "flowing uninterrupted lines, innovative furniture design, flush surfaces and recessed technology" according to the company. Its in-house design studio created the winning look to clinch the annual prize, which was announced on September 21, 2020. The prototype Falcon 6X is on schedule to fly and enter service next year, with the largest cabin cross section of any dedicated (ie, not derived from an airliner) business jet, according to the manufacturer.

The Falcon 6X will have the widest, longest and tallest cabin of any business jet.

A 5,500 nautical miles range capability means the Falcon 6X will be able to fly direct from San Francisco to Beijing and from Hong Kong to London.

The recently launched Falcon 10X will be the largest member of the business jet family and the first with a T-tail Dassault Aviation
