Hollocraft Named a Finalist at DIBX 2026

DIBX 2026 Finalist Design: The Hollocraft Autonomous Attritable Aerial Fuel Distribution System

Hollocraft took its aircraft technology in a very different direction at this year’s Defense Industrial Base Accelerator, with a proposal for autonomously delivering fuel in contested environments.

Moving fuel around a battlefield is a lousy problem to have. Fuel is heavy, you need a lot of it, and getting it where it needs to go traditionally means relying on convoys or a relatively small number of expensive logistics aircraft. Both can make attractive targets. So, for this year’s Defense Industrial Base Accelerator (DIBX) Pitch Competition, the DoW asked companies to come up with another way.

The challenge was pretty specific: develop an autonomous system capable of delivering at least 1,000 gallons of fuel over 100 nautical miles. And there was a catch. The mission still had to succeed even if as much as 40 percent of the delivery fleet was lost along the way. 

Hollocraft was selected as one of nine finalists across the competition’s three categories, and one of three chosen to tackle fuel distribution. CEO Jameson Pitts travelled to Philadelphia to pitch the company’s answer: Quad-Wing: Autonomous Attritable Aerial Fuel Distribution. 

So, what’s a Quad-Wing?

The basic idea is surprisingly simple. Instead of putting a lot of fuel aboard one large aircraft, Hollocraft proposed distributing it across a fleet of smaller autonomous aircraft. Lose one aircraft and you lose part of the load, not the entire mission. The remaining aircraft can then adjust their assignments in flight and keep going. 

That’s where the word attritable comes in. The system is designed around the reality that individual aircraft may be lost without bringing the whole operation to a halt.

The aircraft themselves are tailsitter VTOLs. They take off vertically, transition into forward flight and use their wings for efficient cruising, then return to vertical flight when it’s time to land. That means they don’t need a runway or dedicated launch equipment, but they also don’t have to spend an entire 100-nautical-mile trip flying like a multicopter. 

If that sounds a little familiar, it should. It builds on the same basic problem Hollocraft has been working on all along: getting the convenience of vertical takeoff without giving up the efficiency of flying on a wing.

Only this time, there aren’t any passengers. There’s a big tank of fuel.

The clever bit is in the middle

Quad-Wing is built around a modular fuel-body cassette. Depending on how much lift a mission requires, either two or four aircraft can attach to it. 

That lets Hollocraft use the same aircraft family for different payload requirements instead of designing a larger aircraft every time the load gets heavier.

The aircraft are also designed to be compact, stackable and easy to transport by truck, ship or aircraft. Once deployed, they can operate from unimproved locations without runways. 

And they’re meant to work together.

Rather than treating each Quad-Wing as an isolated aircraft flying its own mission, the system coordinates the fleet autonomously. If an aircraft is lost, its work can be reassigned among the remaining aircraft. That’s an important part of meeting a challenge where losing vehicles isn’t considered an exceptional event. It’s part of the scenario you’re designing for. 

Hollocraft developed the proposal with Harmony Aeronautics, which brings propulsion and flight-autonomy expertise to the project. The DIBX proposal builds on tailsitter aircraft that have already demonstrated flight as the team works toward a system designed for contested logistics. 

Three ways to solve the same problem

One of the more interesting things about the DIBX competition was how differently the three Fuel Distribution finalists approached exactly the same challenge.

Cybernet Systems stayed on the ground, proposing autonomous tanker vehicles based around platforms such as the Army’s HEMTT A4. Neya Systems and its partners proposed using autonomous surface vessels to move fuel across water, then transferring it to autonomous ground vehicles for the trip to the tactical edge.  

Hollocraft went over both of them.

Taking the mission into the air means the route isn’t dictated by roads or waterways. Vertical takeoff also means the aircraft doesn’t need conventional aviation infrastructure waiting at either end.

For an aircraft company, it’s a pretty logical answer.

A bigger idea for Hollocraft

Hollocraft started by looking at how electric aircraft could make shorter passenger trips more practical. Quad-Wing is obviously a long way from that original use case, but the engineering behind it isn’t.

Both depend on making vertical takeoff work without accepting the range and efficiency limitations that normally come with it. Both need an aircraft that can get into and out of small spaces and then fly efficiently once it’s in the air.

DIBX gave Hollocraft a chance to apply that thinking to a completely different problem. And making the final round suggests it was an idea worth taking seriously.
