Hermeus Selects Anduril Lattice for Quarterhorse Mk 2
Hermeus partners with Anduril to integrate Lattice autonomy software into the Mach 3 Quarterhorse Mk 2, targeting autonomous flight in 2027.
Hermeus has selected Anduril Industries to integrate the Lattice for Mission Autonomy software into the Quarterhorse Mk 2 high-speed uncrewed aircraft, marking Anduril’s first commercial agreement to supply its autonomy solution for a third-party Group 5 platform.
Announced in a joint press release on September 3, 2026, the partnership aims to achieve the first autonomous flight of the Quarterhorse Mk 2 in 2027. The integration aligns with the United States Air Force (USAF) Collaborative Combat Aircraft (CCA) program’s push for modular systems, demonstrating that advanced hardware and software can be developed independently and combined for high-Mach environments.
Advancing high-Mach autonomous capabilities
The Quarterhorse program, supported by funding from the Pentagon’s Defense Innovation Unit (DIU), targets speeds of Mach 3. Hermeus has maintained an aggressive development timeline, flying its first aircraft in 2025 and reaching supersonic speeds with the Quarterhorse Mk 2.1 exactly 364 days later. The company is currently preparing to fly the Mk 2.2 variant, which was constructed in under a year.
Anduril’s Lattice Software will serve as the core mission planning and execution engine for the Mk 2. Operators will interface with the aircraft using Anduril’s Menace-T command, control, communications, and computing (C4) solution. This system is already utilized by USAF operators to generate sorties with semi-autonomous aircraft.
Speaking to Breaking Defense, Hermeus Chief Executive Officer Zach Shore explained the operational necessity of the Partnerships and the need for scalable command-and-control systems.
“We now need to automate a lot of those flight controls. I want to be able to push a button, have the aircraft spin up, have the aircraft auto takeoff, all those basic features that allow one person to manage multiple platforms,” Shore told the publication.
Validating modular architecture for the CCA program
The agreement serves as a practical application of the Autonomy Government Reference Architecture (A-GRA) standard. By separating the airframe development from the autonomy software, the partnership mirrors the acquisition strategy of the USAF CCA program.
Anduril noted in its September 3 press release that the Hermeus contract validates this focus on modularity. Establishing a common standard ensures cross-compatibility between disparate hardware and software systems, which the company states will accelerate the deployment of autonomous Military-Aircraft.
Brett Darcey, Anduril’s General Manager and Vice President for Mission Autonomy in Air Dominance and Strike, emphasized the maturity of the integration in comments to Breaking Defense.
“We really want to emphasize the fullness of the stack. This isn’t just a mission autonomy science project. This is really readying the Quarterhorse for [autonomous operations],” Darcey stated.
AirPro News analysis
We view this integration as a critical test case for the Pentagon’s broader uncrewed Aviation strategy. If Anduril’s Lattice can successfully manage a third-party airframe operating at Mach 3, it will prove that the A-GRA standard is viable for extreme flight envelopes, not just subsonic loyal wingman platforms. The 2027 flight test will be a major milestone for both companies, potentially opening the door for Anduril to market its autonomy stack to other aerospace Manufacturers while allowing Hermeus to focus entirely on its high-speed propulsion and aerodynamic challenges.

MAFFS Surpasses One Million Gallons in 2026 Fire Season
Military MAFFS crews delivered over 1.07M gallons of fire retardant by Aug 31, 2026, exceeding the totals of the previous two years.
Military-Aircraft aircrews operating the Modular Airborne Fire Fighting System (MAFFS) surpassed one million gallons of fire retardant delivered across the western United States on August 28, 2026, underscoring the severity of a wildfire season that has already eclipsed the total aerial firefighting volumes of the previous two years.
According to an official release from the U.S. National Guard on September 2, 2026, the running total of retardant dropped by MAFFS-equipped Lockheed C-130 Hercules aircraft reached 1,070,017 gallons by August 31. The program provides critical surge capacity for the U.S. Forest Service (USFS) and the National Interagency Fire Center (NIFC) when commercial and federal contract airtankers are fully committed to existing incidents.
Surge capacity in a demanding fire season
The 2026 season ranks among the busiest of the past decade for military aerial firefighting units. The current volume of 1,070,017 gallons significantly exceeds the 410,810 gallons delivered in all of 2025 and the 871,205 gallons dropped in 2024.
While 2026 has seen elevated activity, the busiest MAFFS season of the past decade remains 2021, which saw 2,583,204 gallons delivered, followed by 1,350,298 gallons in 2020. With weeks potentially remaining in the current fire season, the final 2026 figures are expected to climb further.
Col. Jason Little, Commander of the MAFFS Air Expeditionary Group, emphasized the program’s role in supporting civilian agencies during periods of high demand.
“We serve as a surge capability, and our responsibility is to be as prepared and effective as possible when called upon,” Little stated. “We do our best to integrate seamlessly with the federal and state agencies committed to wildland firefighting.”
Multi-unit military coordination
The MAFFS mission requires coordination across multiple military branches and state lines. Operations for the 2026 season are being coordinated from Reno, Nevada, drawing on resources from across the western United States.
The effort comprises crews from the 146th Airlift Wing of the California Air National Guard, the 152nd Airlift Wing of the Nevada Air National Guard, the 153rd Airlift Wing of the Wyoming Air National Guard, and the 302nd Airlift Wing of the Air Force Reserve Command based in Colorado. These units operate C-130 aircraft fitted with specialized MAFFS roll-on/roll-off equipment, allowing standard tactical airlifters to function temporarily as heavy airtankers.
AirPro News analysis
The rapid accumulation of MAFFS flight hours and retardant drops in 2026 highlights a growing reliance on military surge capabilities to manage domestic natural disasters. As commercial airtanker fleets face high utilization rates early in the fire season, the strategic value of the MAFFS program becomes increasingly apparent. We note that the year-over-year volatility in retardant volumes, fluctuating from just over 410,000 gallons in 2025 to over a million before September in 2026, presents ongoing readiness and funding challenges for the participating Air National Guard and Air Force Reserve units. These squadrons must balance unpredictable domestic support missions with their primary military readiness and global airlift requirements.
