Dassault Falcon 900LX Production Appears Halted

Dassault delivered only three new-build Falcon 900LX airframes between January 2025 and July 2026. In the year since July 2025, the manufacturer has not delivered another example, while its primary competitor, the Bombardier Challenger 650, saw 25 deliveries in the same period. The source, Simple Flying, notes that the 900LX listing has also disappeared from Dassault's production page, strongly suggesting active production has ended.

The Final Deliveries

Launched in 2010, the Falcon 900LX is the current production variant of the long-range 900EX, featuring blended winglets and a range of 4,750 nautical miles. Dassault advertised a 7% longer range and 10% better climb performance over the 900EX, allowing it to reach Flight Level 390 in 20 minutes. The basic 900 airframe first entered service in 1986 and evolved through several variants. In October 2016, Dassault launched a modernized 900LX with a new cabin and features like the FalconEye Combined Vision System. As of August 2026, Dassault still lists the 900LX in its product family, but industry publication Flight Plan reported that Dassault's marketing site no longer lists it on its primary aircraft lineup, describing 2026 as the model's final delivery year.

Eroding Trijet Advantages

The corporate trijet was long valued for strong short-field and high/hot performance, steep approach capability, and flexibility over ocean routes. These advantages have now eroded. The corporate industry is moving on from trijets, which are retired from regular commercial passenger use. The Falcon 900 family has been one of the longest-running business jet platforms, but it is now increasingly seen as a legacy aircraft outclassed by modern twin-engine designs. The 900LX's traditional selling point was that its three-engine design could offer performance that twin-engine jets couldn't. That is changing.

The Gulfstream G400 Challenge

The incoming Gulfstream G400 is a newer-generation twin-engine jet that overlaps with the Falcon 900LX's mission. It is powered by a pair of Pratt & Whitney PW812GA engines, while the 900LX uses three Honeywell TFE731 engines. The two aircraft have comparable specifications.

The G400 provides roughly the same broad mission with a modern clean-sheet twin-engine design. Gulfstream claims its advanced engines and aerodynamics deliver 29% more fuel-efficiency than previous-generation aircraft. The G400's first flight was in 2024, but its entry into service, expected in 2025, has been delayed with certification testing ongoing.

Internal Replacement Complications

Dassault's closest replacement for the 900LX is the Falcon 6X, but it sits in a different market category. The 6X is a modern twin-engine ultra-widebody jet with a 5,500 nautical mile range. Dassault calls it the first purpose-built ultra-widebody business jet with the largest cabin in its class. It is a great option for customers needing a big cabin, but not for those looking for a smaller cabin like the 900LX's. As a bigger aircraft, it is more expensive and has larger operational requirements. Dassault's other aircraft in this market part is the Falcon 2000LXS, a twin-engine alternative offering lower operating costs and slightly shorter range. However, it is derived from an airframe whose first flight was in 1993 and faces similar modernization limits as the 900LX.

A Potential Future: The Falcon 4X

One concept Dassault is exploring is developing a smaller Falcon 4X variant of its clean-sheet 6X. The idea would be to fit the two Pratt & Whitney PW812D engines on a smaller, lighter aircraft. A hypothetical Falcon 4X could combine modern aerodynamics and propulsion with a range of 4,000 to 4,500 nautical miles, offering lower acquisition and operating costs than the larger 6X. Should Dassault pursue it, the Falcon 4X could replace both the 2000LXS and the 900LX, allowing a transition away from the trijet design.
