Archer and Karem Collaborate on Hybrid Military VTOL Aircraft
Archer Aviation teams with Karem Aircraft to develop a hybrid-electric VTOL using military-grade tiltrotor tech for defense and long-range missions.

This article is based on an official press release from Archer Aviation. See the original release for full details.
Archer Aviation and Karem Aircraft Partner for Next-Gen Hybrid Military VTOL
Archer Aviation has announced an exclusive collaboration with Karem Aircraft to develop a next-generation hybrid-electric vertical takeoff and landing (VTOL) aircraft. According to the company’s official statement, this partnership aims to integrate Karem’s military-grade Optimum Speed Tiltrotor (OSTR) technology into a new platform designed specifically for defense applications and long-range commercial missions.
This agreement marks a significant expansion of Archer’s strategic focus. While the company continues to certify its all-electric “Midnight” air taxi for urban mobility, this new initiative targets the high-performance requirements of the U.S. military. By combining Archer’s electric powertrain and manufacturing capabilities with Karem’s advanced rotor designs, the companies intend to deliver a “dual-use” aircraft capable of speeds, ranges, and payloads that exceed the limits of current battery-only technology.
Integrating Military-Grade Rotor Technology
The centerpiece of this collaboration is the integration of Karem Aircraft’s proprietary Optimum Speed Tiltrotor (OSTR) technology. Traditional tiltrotors often face aerodynamic compromises, requiring a balance between the high rotor speeds needed for vertical lift and the lower speeds preferred for efficient forward flight. According to the technical details released regarding the partnership, OSTR solves this by allowing rotors to vary their RPM significantly between flight modes.
Performance and Efficiency Gains
By utilizing OSTR, the proposed aircraft can maintain high RPM for hover and switch to lower RPM for quiet, efficient cruise flight. The press release notes that this technology has already been validated by the U.S. Army through the Joint Multi-Role Technology Demonstration (JMR-TD) program. The expected benefits include higher top speeds, extended range through improved fuel efficiency, and a reduced acoustic signature, a critical factor for operating in contested military airspace.
The “Technology Stack” Strategy
This collaboration is part of a broader strategy by Archer to assemble a coalition of defense-focused technologies. The new platform will reportedly combine three distinct layers of innovation:
- Aeromechanics: Karem Aircraft’s OSTR technology.
- Autonomy: Mission systems provided by Anduril Industries, a recent Archer partner.
- Powertrain & Production: Archer’s high-volume manufacturing and electric propulsion systems.
A Distinct Platform: Beyond the Midnight
While Archer’s flagship “Midnight” aircraft is designed for short urban hops of approximately 20 to 50 miles, the new hybrid platform represents a separate product line tailored for heavy logistics and tactical utility. The company indicates that the U.S. military requires “runway-independent” logistics capabilities that battery-electric aircraft cannot currently fulfill due to energy density limitations.
Hybrid Propulsion for Heavy Payloads
To meet these rigorous demands, the new aircraft will utilize a hybrid-electric propulsion system, employing a turbine generator to power electric motors. This configuration offers the vertical agility of a helicopter combined with the range and speed of a fixed-wing airplane. According to the announcement, the targeted payload for this military-focused aircraft is between 1,200 and 2,000+ pounds, significantly higher than the passenger capacity of the Midnight air taxi.
“The U.S. military (specifically the Army) has identified that battery-only eVTOLs lack the range and endurance for tactical logistics and rescue missions.”
AirPro News Analysis
The inclusion of Karem Aircraft adds substantial engineering pedigree to Archer’s defense ambitions. Founded by Abe Karem, widely known in the industry as the “Dronefather” for his creation of the Predator drone, Karem Aircraft has a history of developing high-efficiency designs like the A160 Hummingbird. For Archer, this partnership likely serves to de-risk its entry into the defense sector by leveraging proven military tech. Furthermore, the shift toward hybrid propulsion acknowledges a pragmatic reality: while all-electric solutions suit urban air mobility, the energy requirements of military logistics and long-range transport still demand the energy density of fuel-based hybrid systems.
Strategic Implications for Defense
The collaboration explicitly targets operations in “contested environments.” The ability to fly low, fast, and quiet is essential for evading radar and acoustic detection. By leveraging electric motors for quiet operations and OSTR for speed, the companies aim to fill a capability gap for the military, providing a logistics platform that does not rely on vulnerable runways.
While the immediate focus remains on defense contracts, Archer has characterized the platform as “dual-use.” This suggests that the hybrid technology developed for the Pentagon could eventually be adapted for commercial markets, potentially serving regional routes that are too long for battery-electric air taxis but too short for traditional commercial jets.

L3Harris Completes First 35 Viper Shield Production Units
L3Harris reaches a production milestone for the AN/ALQ-254(V)1 Viper Shield, with 233 units on backlog for eight allied F-16 operators.

L3Harris Technologies has completed manufacturing the first 35 production units of its Viper Shield electronic warfare system, initiating a production ramp-up to fulfill a 233-unit backlog for international F-16 Fighting Falcon operators.
In a press release issued on September 3, 2026, the company announced the milestone at its Clifton, New Jersey, facility. The event also marked the assembly of the first external pod configuration utilizing production-standard hardware. The AN/ALQ-254(V)1 Viper Shield currently stands as the only F-16 electronic warfare suite in active production.
Fulfilling the international backlog
L3Harris is scaling operations to meet demand from eight allied nations that have collectively ordered 233 Viper Shield systems. These international operators have contributed to a $1 billion shared investment funding the development, laboratory testing, flight testing, and current production of the suite.
“The foreign investment is funding development, lab testing, flight testing and current production of Viper Shield systems, which presents the United States with a savings opportunity to avoid upfront costs,” said Chris Aebli, President, Communications & Spectrum Dominance, L3Harris.
Aebli noted that this shared investment means the U.S. Air-Forces and Air National Guard could benefit from joining the program without bearing the initial development burden.
Recent flight testing and fleet integration
The production milestone follows a series of recent technical and commercial validations for the Viper Shield program. On August 5, 2026, L3Harris reported the completion of two-ship flight testing at Edwards Air Force Base in California. During these tests, F-16C and F-16D models flew together with Viper Shield hardware to validate the digital architecture and real-time response capabilities in multi-aircraft scenarios.
Shortly after the Edwards Air Force Base tests, the government of Peru officially selected the Viper Shield system on August 18, 2026, for its incoming F-16 Block 70 fleet. The system is designed to be fully interoperable with the APG-83 Active Electronically Scanned Array (AESA) radar, a standard component of the Block 70/72 configuration and a common upgrade for legacy F-16 airframes.
AirPro News analysis
We note that L3Harris is leveraging international procurement to mature the Viper Shield system before heavily marketing it to domestic operators. By relying on foreign military sales to fund the $1 billion development and testing phase, the manufacturer has effectively de-risked the AN/ALQ-254(V)1 for the U.S. Air Force and Air National Guard. As legacy F-16 fleets undergo radar upgrades to the APG-83 AESA, the interoperability of the Viper Shield positions it as a logical bolt-on enhancement for operators looking to modernize their electronic warfare capabilities without funding a clean-sheet development program.

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.
