SINGAPORE—Final assembly of the first ultra-long-range Dassault Falcon 10x is expected to begin in the second half of 2024, the OEM confirms.

Deliveries of the high-speed business jet with a range of 7,500 nm are then slated to begin in 2027, Dassault executives tell Aviation Week on the sidelines of the Singapore Airshow.

“We’ll begin—for the first one—the final assembly this year, specifically in the second half,” says Carlos Brana, EVP of civil aircraft at Dassault. “As fast as we can.”

Entry into service for the clean-sheet aircraft had previously been planned for late 2025. Featuring a maximum certified altitude of 51,000 ft. with two Rolls-Royce Pearl 10X engines, the jet will have a cruise speed of Mach 0.85 and a top speed of Mach 0.925.

Dassault’s smaller 5,500 nm-range Falcon 6X is on display here at the Singapore Airshow. It is the first of the type to be put into service has logged more than 200 hr. of flying since November 2023 on roughly 150 flights. Dassault's first customer delivery of the type has also taken place. According to the Aviation Week Network Fleet Discovery database, the first 6X went to Switzerland-based Take Off Aviation AG, as previously reported.

“They are impressed by the cabin size, by the quietness of the cabin, the smoothness of the ride,” says Brana of its first customer.

Dassault's wholly owned subsidiary ExecuJet MRO says it is “following the logical steps” to make sure they are prepared to support maintenance on the new airframes.

“For us, it's just a new product,” says ExecuJet MRO Services President Graeme Duckworth. “Our guys are fully up to speed to support the aircraft.”

The company delivered 26 Falcons in 2023, rather than the 35 originally expected, but is progressing on efforts to alleviate supply chain constraints.

“We had issues with the supply chain, and we have worked diligently with those guys to fix the issues,” Brana says. “It’s an ongoing improvement right now. We want to make sure that this improvement is steady … the most important thing in production is stability.”
