Dassault now has 2 Falcon 10X test jets in the air

Dassault has begun flying a second Falcon 10X prototype, with aircraft serial number 2 making its first takeoff from Mérignac on September 24. The 10X is the French maker’s largest business jet and is aimed at the ultra-long-range top end of the market.

• Second Falcon 10X prototype first flew on September 24, 2026
• Dassault confirmed the milestone on October 7, 2026
• Flight-test work is now using 2 aircraft
• Falcon 10X is Dassault’s flagship long-range business jet

Dassault Aviation has moved the Falcon 10X program into a busier phase, confirming that a second prototype is now flying. The aircraft, serial number 2, made its first takeoff from Mérignac in France on September 24.

The key number is 2: Dassault now has two Falcon 10X test aircraft in the air, giving engineers more capacity to collect performance, systems and handling data. The aircraft is Dassault’s biggest business jet and sits in the same high-end long-range category as the Gulfstream G700 and Bombardier Global 8000.

For buyers, the news matters because test-fleet size is a visible sign of progress on a delayed, complex program. For the market, it keeps Dassault in the race at the very top of private aviation, where range, cabin size and certification timing can shape order decisions for years.
