Dassault Ends Falcon 900LX Production After 40 Years

Dassault appears to have ended active production of its Falcon 900LX business jet. According to Simple Flying, only three new-build airframes were delivered between January 2025 and July 2026, with none reported since. In the same period, its primary competitor, the Bombardier Challenger 650, saw 25 deliveries.

The aircraft's listing has also vanished from Dassault's primary production webpage. This strongly suggests the iconic trijet's manufacturing run is over after four decades.

The Final Deliveries

Launched in 2010, the Falcon 900LX is the latest variant of a platform that first entered service in 1986. Dassault advertised a modernized version in 2016 featuring an updated cabin and the FalconEye Combined Vision System. The company claimed the 900LX offered a 7% longer range and 10% better climb performance than its predecessor, the 900EX.

By August 2026, however, industry observers noted its disappearance from marketing materials. The Flight Plan reported that Dassault's own site no longer listed the F900LX on its primary aircraft lineup, leaving only a broken link. Industry brokers described 2026 as the model's final delivery year.

Eroding Trijet Advantages

The corporate aviation industry is moving on from trijets. These aircraft were once valued for strong short-field performance, steep approach capability, and flexibility over ocean routes before twin-engine ETOPS rules evolved. Those advantages have now eroded.

All trijets are retired from regular commercial passenger use. Legacy freight-converted MD-11s are being rapidly phased out. The Falcon 900 family has been the most successful business jet platform of its kind. It is now increasingly seen as a legacy design outclassed by modern twins.

Competitive Pressure from the Gulfstream G400

The incoming Gulfstream G400 presents a direct challenge. It is a newer, clean-sheet twin-engine design that overlaps with the 900LX's mission. While preliminary, key comparative figures highlight the shift.

The G400's price is nearly identical to the 900LX's. Gulfstream claims its advanced engines and aerodynamics deliver 29% better fuel efficiency than previous-generation aircraft. Certification testing is ongoing after a delayed entry from an expected 2025 service date.

Internal Replacement Challenges

Dassault's own newer models complicate replacing the 900LX. The closest candidate is the Falcon 6X, a modern twin with a 5,500 nautical mile range. Dassault calls it the first purpose-built ultra-widebody business jet. However, it is a significantly larger, more expensive aircraft designed for a different market segment.

Many 900LX customers do not need such an expansive cabin or extreme range. The Falcon 8X remains Dassault's only current-production trijet, but it is an evolution of the larger Falcon 7X. The Falcon 2000LXS, a twin derived from a 1993 design, faces similar modernization limits as the 900LX.

Dassault markets the 2000LXS as the most fuel-efficient aircraft in its category with the lowest operating costs. The company states its two PW308C engines, each managed by a FADEC system, offer high efficiency. These claims are expected to face growing pressure from newer competitor aircraft.

A Potential Future: The Falcon 4X

One concept Dassault is exploring is a smaller variant of the 6X, tentatively called the Falcon 4X. The idea is to fit the same Pratt & Whitney PW812D engines on a lighter airframe. A hypothetical Falcon 4X could offer a range between 4,000 and 4,500 nautical miles.

Such an aircraft would combine modern aerodynamics and propulsion with lower acquisition and operating costs than the 6X. It could potentially replace both the aging Falcon 2000LXS and the now-ended Falcon 900LX, allowing a full transition away from the trijet design.
