The Phantom 3500 is a clean-sheet design that introduces a series of innovations to the super-midsize jet category. Among its most striking features is the industry’s first windowless passenger cabin, where high-definition digital displays will provide real-time external views. The aircraft is designed to deliver greater efficiency, speed, and cabin space, while also operating from shorter runways.

With a cabin height of 6 feet 5 inches, the Phantom 3500 is configured to seat eight to nine passengers. It features a transonic super-laminar flow architecture and advanced aerodynamics, supported by precision all-carbon-fiber composites. The design is expected to cut fuel burn by more than 60%. Power will come from Williams Aerospace engines.

The jet is scheduled for its first flight in 2027, with entry into service projected for 2030.

Flexjet Chairman Kenn Ricci highlighted the company’s long-standing focus on innovation:

“For 30 years, Flexjet has led through innovation opposed to imitation, introducing tomorrow’s standards, not reacting to yesterday’s expectations. The Phantom 3500 exemplifies that approach perfectly, marking a bold step into a future where an aircraft’s efficiency and sustainability stand alongside speed, comfort, and range as defining standards. This collaboration with Otto Aerospace further affirms our leadership role in delivering to fractional aircraft Owners the future of luxury private aviation.”

Headquartered in Fort Worth, Texas, Otto Aerospace is developing the Phantom 3500 with a team that includes former leaders from Boeing, Textron, General Dynamics, and Lockheed, alongside entrepreneurs and engineers. The company is positioning the new aircraft as a benchmark in efficient, sustainable, and advanced private aviation.
