Contract with Flexjet marks the first major sale of the ultralight business jet, which promises up to 60% fuel savings
American company Otto Aerospace has announced its first major contract for the Phantom 3500, an ultralight business jet currently under development. The agreement was signed with Flexjet, a leader in private aviation, which placed a firm order for 300 aircraft, with additional options for future expansion.

In addition to the purchase, the deal foresees that Flexjet’s own maintenance network may become an authorized Otto Aerospace service center.
Innovation and efficiency
Designed to set new standards in business aviation, the Phantom 3500 will have a range of up to 3,200 nautical miles (about 5,926 km) with four passengers. The aircraft incorporates groundbreaking solutions such as a low-drag fuselage and simplified wing construction with “super-laminar” flow, which significantly reduces aerodynamic resistance.
One of the project’s boldest features is the elimination of windows, a measure that helps reduce weight and drag. With these choices, Otto estimates fuel savings of up to 60% compared to jets in the same category.
The first flight is scheduled for 2027, with deliveries beginning in 2030.

Flexjet CEO Kenn Ricci emphasized that the company always bets on “innovation, not imitation” and stated that the Phantom 3500 reflects this philosophy. Flexjet, which already operates models such as the Gulfstream G700, Bombardier Challenger 300, and Embraer Praetor and Phenom, sees the new jet as a key addition to expand its fleet with a focus on sustainability and efficiency.
Meanwhile, Otto Aerospace CEO Paul Tow stressed that the contract “speaks for itself and reflects the direction aviation is heading.” According to him, the Phantom 3500 represents a decisive moment for the industry’s transition toward more sustainable and efficient air transport.
