The Dassault Falcon is a family of business jets, manufactured by Dassault Aviation. July 2017 saw the 2,500th Falcon delivered – a Falcon 900LX – since the first Falcon 20 was handed over to a customer in 1965. The fleet has accumulated 17.8 million hours of flight time with approximately 1,230 operators in 90 countries and as of July 2017 more than 2,100 Falcons are in service. On 13 December 2017, Dassault abandoned the Silvercrest due to technical and schedule risks, ended the Falcon 5X development and launched a new Falcon with the same cross section, Pratt & Whitney Canada engines and a 5,500 nmi (10,200 km) range for a 2022 introduction. Dassault offers the midsize Falcon 2000S/LXS twinjet, the long-range Falcon 900LX trijet and ultra-long range Falcon 7X/8X trijets.
