In an Otay Mesa hangar, San Diego aerospace startup Natilus is quietly trying to crash the Boeing and Airbus party. The company is building a family of triangular, blended wing aircraft at Brown Field, starting with its KONA regional cargo freighter, and has unveiled a larger dual deck Horizon Evo passenger concept that is designed to use existing airport gates. Natilus and industry coverage point to prototype flights in the late 2020s and commercial service in the early 2030s if certification goes smoothly, a timeline that could make San Diego one of the few U.S. homes for a homegrown rival to the big two jet makers.
What Natilus Is Building
According to Natilus, KONA is a regional blended wing freighter, while the Horizon Evo is a dual deck passenger jet that can seat roughly 150 to 250 people depending on layout. The company pitches the blended wing body as a way to boost internal volume by about 40 percent for cabin or cargo, while cutting fuel consumption by around 30 percent. That extra space, paired with lower fuel burn, lets airlines rethink how they mix cargo and seating, an option Natilus argues could be especially appealing to low cost and regional carriers that sweat every inch of cabin and belly space.
Why Airlines Are Paying Attention
Analysts say the allure is pretty simple: spread lift across more of the airframe, get better efficiency. Natilus projects roughly 30 percent lower fuel burn and a meaningful bump in payload compared with current narrowbodies. "Radically new thinking," is how airline analyst Henry Harteveldt summed it up to Axios, adding that the concept could evolve into a real challenge to the Boeing Airbuses duopoly. Trade coverage notes that the company is moving beyond models and wind tunnel tests into subscale prototypes and early assembly as it raises money for flight testing, according to FLYING.
From Otay Mesa Hangar to Certification Hurdles
Brown Field gives Natilus a nearby assembly and test site, but turning hangar builds into certified passenger jets is a long, expensive slog. The City of San Diego lists Brown Field's primary runway at 7,972 feet and notes that the airport serves as a reliever for Lindbergh Field, a setup that helps with early taxi and low altitude testing. Natilus has said it plans to enter the market first with cargo aircraft to bring in revenue and prove out the design while it works through FAA approvals and looks for a full scale production site, as detailed by Natilus.
Money, Orders and the Road Ahead
The financial backing is still early stage. The company closed a $28 million Series A in February 2026 to fund KONA prototype work, according to Aviation Today. Industry reporting puts Natilus' order book in the mid hundreds of aircraft, roughly $24 billion in reservations, signaling serious commercial curiosity even if many of those deals are still conditional. Analysts caution that certifying an all new aircraft family and ramping up production will take far more capital, long timelines and tight coordination with airlines and airports before travelers see a blended wing jet pulling up to their gate, according to Site Selection.
