Q: When will the Phantom 3500 be available? A: The first flight is expected in 2027, with FAA Part 25 certification and entry into service targeted for 2030.
Q: What makes the Phantom 3500 different from other business jets? A: It uses laminar-flow aerodynamics, all-carbon-fiber composites, and large panoramic passenger windows.
BENTONVILLE, Ark. - Otto Aerospace in Jacksonville, Fla., announced the launch of the Phantom 3500 aircraft at the UP.Summit in Bentonville, Ark. The super-midsize jet is priced at about $19.5 million and is expected to take its first flight in 2027, with Federal Aviation Administration (FAA) Part 25 certification and entry into service targeted for 2030.
At the event, Otto unveiled a full-scale mockup of the Phantom 3500, which the company says will reduce fuel burn by more than 60 percent compared with traditional designs. The clean-sheet jet utilizes laminar-flow aerodynamics and all-carbon-fiber composites to enhance efficiency and lower costs.
"Business jets have long relied on derivative designs built from traditional aluminum structures, aerodynamics, and manufacturing techniques from decades past," said Paul Touw, CEO of Otto Aerospace. "Freed from legacy systems and guided by a true clean-sheet, ultra-efficient vision for the future, we rethink everything to unlock performance gains once thought impossible."

When powered by sustainable aviation fuel (SAF), Otto says the Phantom 3500 will cut emissions by more than 90 percent while lowering fuel costs by 40 percent. At a cruise speed of 590 mph, the company says that the aircraft achieves CO2 emissions per seat mile nearly equal to electric vehicles traveling at 55 mph, while flying at altitudes where contrails rarely form.
The jet will also feature ultra-wide passenger windows, spanning 72 inches, made possible by the company’s SuperNatural Vision technology. The windows are designed to be lighter, quieter, safer, and more energy efficient.
Production is planned at Otto’s 1-million-square-foot smart factory at Cecil Airport in Jacksonville. The $515 million project is supported by the State of Florida and will use robotics, automation, digital twin technology, and AI-enabled systems to streamline production.
