Hermeus Quarterhorse Mk 2.1 Achieves Supersonic Flight at Mach 1.21
Hermeus’s uncrewed Quarterhorse Mk 2.1 reached Mach 1.21, becoming the fastest unmanned aircraft in a rapid development milestone.

Hermeus Quarterhorse Mk 2.1 Achieves Supersonic Flight in Historic Milestone
On May 26, 2026, Atlanta-based defense manufacturers Hermeus announced a historic aerospace milestone: its uncrewed Quarterhorse Mk 2.1 aircraft successfully broke the sound barrier. Reaching a top speed of Mach 1.21 during its third test flight, the achievement marks the first time a privately developed, uncrewed aircraft has achieved supersonic flight.
The flight, conducted out of Spaceport America over the White Sands Missile Range airspace in New Mexico, underscores Hermeus’s rapid iterative development model. According to the company’s press release, the supersonic milestone occurred less than three months after the Mk 2.1’s maiden flight in early March 2026, and exactly 364 days after the first flight of its predecessor, the Mk 1, in May 2025.
This rapid prototyping approach aims to drastically shorten traditional defense procurement cycles. The program has drawn significant interest from the U.S. Department of Defense as the military seeks to counter near-peer adversaries with high-speed, uncrewed capabilities that can shorten response times in contested environments.
The Quarterhorse Mk 2.1 and the Path to Supersonic
Aircraft Specifications and Flight Details
The Quarterhorse Mk 2.1 is a remotely piloted aircraft roughly the size of an F-16 fighter jet. It features a delta wing design and a variable inlet, and is powered by a modified afterburning Pratt & Whitney F100 engine, the same engine family utilized in modern fighter aircraft like the F-16.
Hermeus notes in its release that the Mk 2.1 is nearly three times larger and four times heavier than the previous Mk 1 prototype. Despite this significant increase in scale and mechanical complexity, the company achieved supersonic flight on only the aircraft’s third test flight, cementing the Mk 2.1 as the fastest unmanned aircraft flying today.
A Hardware-Rich Approach
The speed of this development is a core component of Hermeus’s corporate strategy. Rather than relying solely on decades-long simulation and development cycles, the company employs a “hardware-rich” iterative approach. By designing and building physical aircraft in quick succession, Hermeus gathers real-world flight test data to rapidly refine its engineering.
“This flight demonstrates a pace of execution that is extremely rare in modern aviation. Our country’s ability to deliver new asymmetric military capability at scale depends on teams that can solve hard technical challenges quickly. That’s exactly what we’re proving with each test flights we conduct and each new aircraft we build at Hermeus.”
The above statement was provided by AJ Piplica, Co-founder and outgoing CEO of Hermeus, in the official press release.
Future Roadmap and Hypersonic Ambitions
Stepping Stones to Mach 5
While breaking the sound barrier is a major achievement, Hermeus’s ultimate goal is sustained hypersonic flight, defined as speeds of Mach 5 and above. The Quarterhorse program serves as a critical stepping stone toward this objective.
According to the company’s roadmap, the next iteration, the Quarterhorse Mk 2.2, is already under construction. This upcoming aircraft will utilize Hermeus’s proprietary “Chimera II” turbine-based combined cycle propulsion system. A subsequent Mk 2.3 prototype is also in the planning stages.
Darkhorse and Halcyon
The technologies validated through the Quarterhorse test flights will directly feed into two planned operational aircraft. The first is Darkhorse, a hypersonic military aircraft designed to operate in contested environments. The second is Halcyon, a proposed 20-passenger civil hypersonic jet that aims to reduce intercontinental travel to a fraction of current commercial flight times.
Corporate Restructuring and Financial Backing
Leadership Transition
Alongside its technical milestones, Hermeus recently announced a significant executive transition. Effective June 1, 2026, current President Zach Shore will assume the role of Chief Executive Officer. Founding CEO AJ Piplica will transition to Executive Chairman, where he will focus on long-term capital strategy, board leadership, and investor relations.
In a recent statement regarding the transition, Shore emphasized the company’s operational focus as it scales its testing programs:
“Hermeus is at an inflection point. We are currently running more parallel lines of effort than at any point in our history. My focus remains on delivering the capabilities the American warfighter needs by ensuring we execute on our flight campaigns and scale our business effectively.”
Financial Position
To support these intensive flight test campaigns, Hermeus has secured substantial financial backing. The company has raised over $500 million in private capital to date, which includes a recent $350 million Series C funding round, positioning it well for its upcoming hardware iterations.
AirPro News analysis
We view Hermeus’s 364-day turnaround between the Mk 1 and Mk 2.1 as a stark contrast to traditional aerospace development, which often spans decades. The successful Mach 1.21 flight validates the “hardware-rich” prototyping model that has become increasingly popular among new defense contractors. Furthermore, Piplica’s deliberate use of the historical term “Department of War” in the press release, noting that their customers are “paying close attention to how fast this program is moving”, signals a clear marketing strategy aimed at highlighting the urgent, tactical utility of affordable, attritable high-speed drones in modern geopolitical conflicts.
Frequently Asked Questions

GE Aerospace and Magellan Sign F414 MRO MOU for Canada
GE Aerospace and Magellan Aerospace signed an MOU at Farnborough to establish a Canadian F414 engine MRO center if Canada selects the Gripen E.

GE Aerospace and Magellan Aerospace Corporation signed a Memorandum of Understanding (MOU) on July 22, 2026, at the Farnborough International Airshow to establish a Canadian MRO center for the F414-GE-39E engine. The agreement is entirely contingent on the Government of Canada selecting the Saab JAS 39 Gripen E for its future fighter fleet.
Announced in a GE Aerospace press release, the proposed MRO work would take place at Magellan’s facility in Mississauga, Ontario. The partnership aims to position Magellan as Canada’s domestic center of excellence for F414 engine sustainment, guaranteeing sovereign support capabilities for the Royal Canadian Air Force (RCAF) if the Gripen E is acquired.
Industrial offsets and the Gripen E campaign
The MOU represents a calculated component of a broader industrial offset campaign by Saab AB and its suppliers to secure a portion of Canada’s fighter procurement contract. The Canadian government is currently reviewing its fighter jet strategy. While Ottawa previously committed to purchasing a fleet of 88 Lockheed Martin F-35A Lightning II Military-Aircraft, the government is evaluating a potential mixed fleet that could include domestically built Gripen E fighters.
To strengthen the Gripen’s bid, Saab has been securing agreements with Canadian aerospace firms to promise domestic job creation and technology transfer. This engine sustainment agreement follows a similar MOU signed on July 17, 2026, between Saab and Canadian aviation training firm CAE Inc. to cooperate on advanced fighter pilot Training.
Engine sustainment and domestic capabilities
The F414 engine family has accumulated more than 5 million flight hours globally. The new agreement builds on a 60-year working relationship between GE Aerospace and Magellan Aerospace Corporation.
Paul Ferraro, Vice President of Defense Engines & Services at GE Aerospace, stated that the agreement spans both military and commercial engines and will ensure the RCAF has in-country access to sustainment services to maintain F414 readiness.
Haydn Martin, Vice President of Business Development, Marketing, and Contracts at Magellan Aerospace Corporation, emphasized the operational benefits of the proposed partnership.
“Should the Saab JAS 39 Gripen E aircraft be selected, Magellan Aerospace will be ready to provide world-class engine maintenance, repair and overhaul services that enhance operational readiness for the Royal Canadian Air Force while maintaining highly skilled Canadian jobs, developing advanced technical expertise, and strengthening Canada’s long-term defence industrial capacity,” Martin said.
AirPro News analysis
We view this MOU as a clear signal that the competition for Canada’s fighter fleet remains highly active despite the initial F-35A selection. By lining up domestic heavyweights like Magellan and CAE, Saab is directly addressing Ottawa’s stringent Industrial and Technological Benefits (ITB) policy requirements. If the Government of Canada opts for a mixed fleet, establishing sovereign MRO capabilities for the F414 engine will be a critical factor in mitigating supply chain risks and ensuring RCAF operational independence. Until a formal procurement decision is finalized, these agreements remain strategic positioning rather than guaranteed Contracts.

CBP AMO Orders 10 Airbus H125 Helicopters for Fleet Expansion
CBP Air and Marine Operations contracts for 10 Airbus H125 helicopters, expanding a 30-year fleet of over 100 rotary-wing aircraft.

U.S. Customs and Border Protection Air and Marine Operations (CBP AMO) has finalized a contract to acquire 10 additional Airbus H125 helicopters, expanding a fleet modernization effort that relies heavily on the single-engine platform for border security and law enforcement missions.
In a press release issued on July 7, 2026, Airbus confirmed the agreement, which reinforces a three-decade relationship between the federal agency and the aerospace manufacturer. The new helicopters will be assembled at the Airbus Helicopters production facility in Columbus, Mississippi.
Expanding the airborne law enforcement fleet
The latest acquisition builds upon a previous order placed in August 2020, when CBP AMO contracted for 16 H125 helicopters to upgrade its aging rotary-wing assets. The agency currently operates a total fleet of more than 240 aircraft, which includes over 100 helicopters from the Airbus H120 and H125 families delivered over the past 30 years.
The H125, formerly known as the Eurocopter AS350, is utilized by CBP AMO for a variety of demanding flight profiles, including border surveillance, suspect pursuit, and general public safety operations across the United States.
Bart Reijnen, Head of the North America Region for Airbus Helicopters, stated that the expansion “underscores the long-standing collaboration” between the manufacturer and the federal agency. He added that the selection highlights the trust placed in the H125 to execute critical public safety missions under demanding conditions, with Airbus committing to provide comprehensive services to maintain mission readiness.
Virtual reality integration for pilot training
As CBP AMO increases its H125 inventory, the agency is simultaneously overhauling how it trains the personnel who fly them. In November 2025, CBP became the first federal law enforcement agency and the first branch of the U.S. Department of Homeland Security (DHS) to integrate virtual reality into its aerial training program.
According to reporting by FLYING Magazine, the agency awarded a contract to adopt an FAA-qualified Airbus H125 virtual reality flight simulator developed by Loft Dynamics. The simulator is being installed at the CBP AMO training center in Oklahoma City, where it will be used to train the agency’s roster of more than 600 pilots.
AirPro News analysis
We view CBP AMO’s continued investment in the H125 platform as a clear indicator of the agency’s preference for fleet commonality. Operating a standardized fleet of over 100 H125-family helicopters significantly reduces maintenance overhead, streamlines supply chains, and simplifies pilot transition training. Furthermore, Airbus’s strategy of assembling these aircraft in Columbus, Mississippi, likely plays a crucial role in navigating federal procurement requirements, ensuring that the European manufacturer remains highly competitive for U.S. government contracts. The parallel investment in Loft Dynamics’ VR simulators suggests the agency is preparing for a sustained, long-term operational lifespan for the H125 fleet.

Bombardier Defense Signs 10-Year Support Deal With Sweden
Bombardier Defense and FMV finalized a 10-year support agreement for Sweden’s two Global 6500 TP 106 military transport aircraft.

Bombardier Defense and the Swedish Defence Materiel Administration (FMV) finalized a 10-year Services Support Agreement on July 22, 2026, securing long-term maintenance and operational readiness for Sweden’s newly acquired fleet of two Global 6500 transport aircraft.
Announced during the Farnborough International Airshow in a company press release, the agreement enrolls the Swedish Armed Forces (SWEAF) in Bombardier’s Smart Services Defense program. The comprehensive support package covers parts, labor, and engineering expertise for the aircraft, which are designated as the TP 106 in Swedish military service and replace the nation’s aging Gulfstream IV and Gulfstream G550 head-of-state transport fleet.
Fleet modernization and delivery timeline
The targeted acquisition deal for the two aircraft was valued at SEK 1.1 billion ($113 million) and formalized in May 2025, according to reporting by Aviation International News. The rapid procurement was enabled by utilizing existing airframes previously operated in Bombardier’s demonstration fleet, which were subsequently modified to meet Swedish Military-Aircraft requirements.
The formal handover of the aircraft took place on June 1, 2026, at the Uppland Wing F 16, as reported by Nordic Defence Sector. The aircraft will be operated by the 75th Swedish Civil Aviation Squadron at Skaraborg’s F7 Air Fleet, based at Stockholm Arlanda Airports (ARN), primarily conducting VIP and head-of-state transport missions.
Smart Services Defense and operational commonality
The 10-year agreement provides comprehensive cost coverage and logistical support for the new fleet. Bombardier stated the program includes landing gear and auxiliary power unit maintenance, ground support equipment, technical assistance, and access to mobile response teams.
Paul Sislian, Bombardier’s Executive Vice President of Aircraft Sales and Aftermarket Services, noted the program provides seamless original equipment OEMs support for the Swedish military.
“Through our Smart Services Defense program, the Swedish Armed Forces will benefit from seamless OEM support, enhanced readiness and predictable lifestyle costs, giving them the confidence to stay focused on the mission while we support their aircraft every step of the way,” Sislian said.
The selection of the Global 6500 platform offers strategic maintenance and operational commonality with Sweden’s incoming airborne early warning and control (AEW&C) fleet. The Swedish Armed Forces are procuring the Saab GlobalEye, designated the S 106, which is also built upon the Bombardier Global aircraft family architecture.
AirPro News analysis
The 10-year support agreement underscores a growing trend among defense ministries to rely on commercial OEMs for turnkey lifecycle support rather than developing bespoke military maintenance pipelines for commercial derivative aircraft. By aligning the TP 106 VIP transport fleet with the underlying platform of the S 106 GlobalEye, the Swedish Armed Forces are establishing a unified logistical footprint. We view this procurement Strategy as a highly efficient approach to fleet modernization, reducing training burdens for maintenance personnel and ensuring higher dispatch reliability through Bombardier’s established global civilian support network.
