Natilus Advances HORIZON EVO Toward Certification With Dual-Deck Redesign for Airlines

New updates have been reported about Natilus.

Natilus is advancing its HORIZON EVO blended‑wing‑body passenger aircraft toward Federal Aviation Administration certification and commercial fleet deployment, unveiling a major redesign driven by regulator and airline feedback. The U.S. manufacturer has shifted HORIZON EVO from a single‑deck to a dual‑deck configuration to improve certifiability, operational practicality, safety, and passenger experience, targeting entry into commercial service in the early 2030s.

The updated design retains compatibility with existing airport gates and ground systems while adding a dedicated upper passenger deck and lower deck for standard cargo containers, enabling airlines to optimize both load factor and belly freight revenue. Natilus emphasizes enhanced egress paths, additional overhead storage, multiple cabin aisles, and more windows across the upper deck, positioning HORIZON EVO as a response to current industry pain points around safety scrutiny, constrained aircraft supply, and customer experience.

Key specifications include a cruise speed above Mach 0.78 at 35,000 feet, Jet A or sustainable aviation fuel capability, and the option for PW1500F geared turbofans or CFM LEAP engines, aiming to align with airline maintenance and fleet commonality preferences. The aircraft is classified in Gate Class C4, with seating flexibility from 150 passengers in a three‑class layout up to 250 in single‑class, and an economy configuration of four‑by‑three seating inside a 7‑foot-high, 26‑foot-wide cabin.

Cargo capacity is central to the business case: the upper deck can carry up to 16 AAA containers with 8,500 cubic feet of volume, while the lower deck accommodates 12 LD3‑45 containers with 2,600 cubic feet, giving carriers added revenue streams and route flexibility. With eight exits and a focus on faster turnarounds via multiple aisles and seamless ground handling, Natilus is positioning HORIZON EVO as a high‑throughput narrowbody alternative in a market where fleets are projected to double over the next two decades.

Backed by more than 570 pre‑orders across its aircraft family, valued at approximately $24 billion, Natilus claims its blended‑wing‑body architecture can cut fuel burn by about 30 percent, reduce operating costs by 50 percent, and boost payload capacity by 40 percent versus conventional designs. Investor Dennis Muilenburg, CEO of New Vista Capital and former Boeing chief, frames HORIZON EVO as a potential solution to the looming supply‑demand imbalance for new aircraft, citing its economics, sustainability profile, and passenger‑centric upgrades.

For executives evaluating future fleet strategy, HORIZON EVO represents a long‑dated but potentially disruptive platform that could diversify narrowbody capacity, particularly on high‑density routes where fuel efficiency, containerized cargo, and higher seat counts drive margin. The certification trajectory, actual performance versus claims, and airline adoption over the next decade will be key determinants of whether Natilus can convert its order book and design advantages into durable commercial scale in the passenger market.
