Flexjet orders 300 windowless ‘Phantom 3500’ jets in $10bn deal

A new aircraft design could redefine private aviation as we know it. The sleek, windowless Phantom 3500 jet by Otto Aerospace promises to cut fuel burn by 60%, and it’s already secured one of the industry’s biggest-ever orders.

At the UP. Summit in Bentonville, Arkansas, Otto Aerospace unveiled its Phantom 3500, a futuristic twinjet with no physical windows. Instead, passengers view the skies through 72-inch interior screens powered by SuperNatural Vision, a system that projects real-time imagery from external cameras.

The launch coincided with a landmark order from Flexjet, the world’s second-largest fractional jet ownership company, which announced plans to acquire 300 Phantom 3500s. Industry analysts estimate the deal could be worth over $10 billion, marking a major shift toward cleaner, more efficient business aviation.

A jet from the future

The Phantom 3500 features a carbon-fibre body and a laminar-flow airframe, designed to dramatically reduce drag and boost fuel economy. Its raked wings, smaller engines, and ultra-lightweight structure allow it to fly up to 3,500 nautical miles, enough for non-stop transatlantic trips.

According to Otto’s Chief Operating Officer, Scott Drennan, the design cuts aircraft weight by nearly half compared with current mid-size jets like the Cessna Citation X or Embraer Praetor 500. “Every component is optimized for efficiency. The fuselage, wings, and even the engines are smaller and lighter, yet deliver more range and performance,” Drennan told Robb Report.

Inside, passengers can expect a 6-foot-5-inch cabin height, providing more headroom than most business jets in its class. Otto plans to begin flight testing by 2027, with certification targeted for 2030.

Redefining how jets are built

Otto Aerospace’s Chief Executive, Paul Touw, described the Phantom as a “clean-sheet revolution,” breaking free from legacy aluminium-based designs that have dominated aviation for decades. “We rethought everything, structure, materials, and systems, to unlock performance gains once thought impossible,” Touw said.

The company is investing heavily in production infrastructure, building a 1-million-square-foot smart manufacturing campus in Jacksonville, Florida, backed by a $515 million incentive package from the state. The site will use robotics and automation to ensure the precision needed for the aircraft’s laminar-flow aerodynamics.

Flexjet Chairman Kenn Ricci hailed the move as “a bold step into a future where efficiency, sustainability, and performance coexist.” Once in service, the Phantom 3500 will become a cornerstone of Flexjet’s next-generation fleet, offering clients a greener, faster, and more futuristic way to fly.

If Otto delivers on its promises, the Phantom 3500 could change private aviation and redefine what the sky itself looks like.
