The Dassault  Falcon 2000 is the latest member of the Falcon business jet line, and is a transcontinental range, slightly smaller development of the Falcon 900 trijet.The Dassault Falcon 2000 shares the 900's huge wing and forward fuselage, but there are a number of design changes. From the start the Dassault Falcon 2000 was designed with a range of 5560km (3000nm) in mind, which is less than the transcontinental 900's range. 

This nice design range removed the need for the redundancy of three engines for long range over water flights, allowing the two new CFE738 engines to be fitted, which offer considerable maintenance and operating economics benefits. The CFE738 engine was developed specifically for the Dassault Falcon 2000 by a partnership of General Electric and Allied Signal, known as CFE. Meanwhile, the 2000's fuselage is 1.98m (6ft 6in) shorter than the 900's and so houses less fuel, passengers and baggage.

The design have been change between the 900 and 2000 is the area ruled rear fuselage. Dassault engineers found that the three engine layout of the 900 to be aerodynamically efficient, whereas the multiple  twin engine design of the 2000 originally would have been comparatively draggy. To combat this and reduce drag to desired levels Dassault designed an area ruled rear fuselage, using its Catia 3 dimensional computer aided design(CAD) program .
