In the Indo-Pacific, which represents more than half of global maritime trade, fuel is the U.S. military’s greatest vulnerability. On October 20th, the Air Force announced funding for a new aircraft that checks two of the department’s most challenging boxes: fuel efficiency and autonomous operations.
We sent a series of questions to Natilus, and Nolan Giblin, COO, responded. His responses are in italics. We previously spoke with the firm’s CEO.
- What specifically will the $3.5 million fund?
Can you break down the RDT&E work between aircraft development, flight testing, defense-specific modifications, and the planned Joint Force demonstration?
The $3.5 million in RDT&E funding will accelerate KONA’s development toward full-scale flight testing and an operational demonstration with the U.S. Joint Force. The work will focus on advancing the common aircraft platform and evaluating its potential to address future intra-theater airlift and contested logistics requirements. We are not developing a separate defense-specific variant.
- What is the timeline from where KONA stands today to first flight and the operationally relevant Air Force demonstration?
Is the aircraft the Air Force will evaluate essentially the same configuration you’re taking through FAA Part 23 certification?
We continue to target 2028 for KONA’s first flight, with entry into service by the end of the decade. The timing of the Joint Force demonstration will depend on the progression of our full-scale flight test program.
The aircraft evaluated by the Air Force will be the same KONA configuration we’re developing for commercial freight operations and FAA Part 23 certification, rather than a separate military variant. Flight testing will support both our certification program and the evaluation of KONA’s potential for contested logistics.
On the certification front, the FAA accepted our Project Specific Certification Plan in June and assigned KONA a project number. The G-1 Issue Paper is the next major milestone.
- You cite roughly 30% lower fuel consumption than comparable conventional aircraft. What aircraft or mission profile are you using as the benchmark for that claim?
And is the advantage primarily coming from the blended-wing-body aerodynamics, the aircraft’s weight, propulsion, or a combination? Can you provide a genuine benchmark? Can you start testing whether KONA’s BWB architecture creates a meaningful cost-per-ton-mile / fuel-per-ton-mile advantage, not merely whether it burns less fuel?
The approximately 30% fuel consumption advantage is primarily attributable to the aerodynamic efficiency of the blended-wing-body configuration, supported by NASA research and validated through three of our own wind tunnel test campaigns.
The broader economic advantage comes from combining that efficiency with approximately 40% greater volumetric cargo capacity. Our analyses benchmark KONA against conventional regional freighters, including the Cessna SkyCourier (C408) on a comparable MTOW basis and the ATR 72 on a comparable cargo-volume basis. Using representative express cargo densities, our modeling indicates approximately 50% lower operating cost per pound of cargo transported.
These are modeled performance and operating economics estimates that we intend to validate through full-scale flight testing.
- The release positions KONA between the C-208 and C-130. What existing aircraft do you actually see KONA replacing or complementing operationally?
In other words, is the opportunity primarily missions that are currently being flown inefficiently by larger aircraft, or missions that don’t have a suitable airlift solution today? If I’m an operator today, what aircraft is performing the mission you’re saying KONA can do better?
KONA is designed to fill a gap in sub-tactical airlift, complementing larger aircraft such as the C-130 rather than replacing them. We see the primary opportunity in Agile Combat Employment (ACE) and distributed logistics resupply missions, where using larger tactical transports for relatively small payloads can be inefficient.
The commercial regional cargo market provides a useful comparison. Operators today rely on a mix of Cessna Caravans, Beechcraft 1900s, Embraer 120s, and Saab 340s to serve different payload and route requirements. KONA is designed to consolidate many of those missions onto a single, more efficient platform with greater payload flexibility and short-field capability. We see a similar opportunity in defense logistics, particularly for smaller, more frequent deliveries to dispersed locations.
- How does KONA’s 3.8-ton payload and 800-nm range change under demanding operational conditions?
For example, what happens to payload-range performance when operating from short fields, hot-and-high environments, or locations with limited infrastructure?
KONA is designed for short-field operations and compatibility with existing cargo handling infrastructure, including military material handling equipment (MHE) and 463L pallets where available. These capabilities are particularly relevant for distributed logistics operations where runway length, infrastructure, and cargo handling resources may be constrained.
As with any aircraft, payload-range performance will vary with operating conditions, including runway length, elevation, temperature, and available fuel. We will validate these performance characteristics through our full-scale flight test program.
- How far along is the optionally piloted capability?
Is the initial Air Force demonstration expected to involve piloted operations, autonomous/remote operations, or both, and what additional development would be required to field an uncrewed version?
Optional piloting has been incorporated into KONA’s design from the outset, rather than being treated as a future retrofit. We’re making the necessary hardware provisions and have in-house software expertise from prior DoD autonomous aircraft programs. We also have the ability to partner with established autonomy providers developing similar capabilities for platforms such as the Cessna 208 and C-130.
Our initial priority is FAA Part 23 certification for single-pilot operations. We believe defense applications could provide an earlier pathway for optionally piloted operations, particularly in contested environments, but the timing and scope of autonomous flight demonstrations have not yet been established.
- How does the military opportunity affect the commercial KONA business case?
Does defense funding accelerate the same airplane you intend to sell commercially, or could KONA ultimately split into distinct commercial and military configurations? And importantly, does having both markets change the production volumes you think are achievable?
Defense funding accelerates development of the same KONA aircraft we’re bringing to the commercial market. We’re not pursuing separate commercial and military configurations or development timelines. The full-scale flight test program will support both FAA certification and the evaluation of KONA’s capabilities for contested logistics.
The opportunity to serve both markets strengthens KONA’s overall business case by expanding its potential customer base and production volumes, while allowing us to leverage a common aircraft design, supply chain, and manufacturing infrastructure. We see defense demand as additive to our existing commercial order book rather than a replacement for it.
