General Atomics Aeronautical Systems, Inc. (GA-ASI) and Hanwha Aerospace successfully demonstrated the Mojave Short Takeoff and Landing (STOL) uncrewed aircraft system operating from a simulated dirt battlefield road in South Korea on September 16, 2026. The medium-altitude, long-endurance (MALE) aircraft departed the Republic of Korea (ROK) Army 513th Aviation Battalion airfield and landed on a narrow tank and artillery live-fire maneuver road at the Seungjin Training Field in Pocheon-si.

Announced via a joint press release, the flight took place during the 2026 Defense Drone Technology Exhibition hosted by the South Korean Ministry of National Defense. The demonstration was designed to validate the ability of a MALE uncrewed aircraft system (UAS) to operate from short, unimproved dirt strips in simulated combat conditions.

Austere field performance and specifications

During the demonstration, the Mojave STOL required less than 200 meters for takeoff and landed within a 100-meter range. The aircraft is powered by a 450-horsepower turboprop engine and supports a payload capacity of up to one metric ton of mission equipment.

GA-ASI CEO Linden Blue stated the demonstration validated the aircraft’s ability to execute tactical missions representative of real battlefield requirements.

“Whether the user needs contested and austere battlefield operations, ISR, weapons delivery, Air-Launched Effects deployment, troop resupply, counter-UAS, or missions requiring short and unimproved roads for takeoff, our aircraft answer the bell,” Blue said.

Hanwha Aerospace partnership and production timeline

The September 16 flight builds on a history of joint development between the two aerospace manufacturers. In October 2025, Hanwha Aerospace and GA-ASI signed a contract to co-develop the Gray Eagle STOL (GE-STOL) variant. Prior to that agreement, the Mojave STOL completed a successful launch from the ROK Navy amphibious landing ship ROKS Dokdo in November 2024.

Hanwha Aerospace plans to establish research, development, and production infrastructure for the Mojave in South Korea. The company is targeting a domestic production share of more than 70 percent once the aircraft enters mass production, aiming to serve the ROK defense industry and expand into global markets.

Buhwan Lee, CEO nominee for Hanwha Aerospace, described the flight as an important milestone in delivering tangible results through the partnership. He noted the company will work closely with the ROK defense industry to develop uncrewed systems for future operating environments.

The production Mojave STOL is scheduled for its Critical Design Review (CDR) in November 2026. The first flight of the production model is expected in 2027.

The successful operation of a MALE UAS from an unimproved dirt road highlights a shift in uncrewed military aviation toward runway independence. Traditional MALE platforms require pristine, lengthy runways, making them vulnerable to early strikes in a peer conflict. By proving the Mojave can operate from austere environments like tank maneuver roads, GA-ASI and Hanwha are directly addressing the geographic and tactical realities of the Korean Peninsula. The mountainous terrain of South Korea demands operational flexibility, and achieving a 70 percent domestic production share would secure the supply chain for the ROK military while positioning Hanwha as a primary exporter in the Asia-Pacific region.

Lockheed Martin is transitioning hypersonic technology from bespoke prototyping to scalable production through a series of 2026 initiatives focused on air-breathing propulsion, advanced composite materials, and high-rate manufacturing.

In a feature published in September 2026, the company detailed its strategy to meet U.S. Department of Defense (DoD) demands for affordable, mass-producible hypersonic systems capable of sustained flight at speeds exceeding Mach 5. The effort consolidates several major milestones achieved throughout the year, including technology demonstrations and supply chain partnerships with GE Aerospace and Albany Engineered Composites.

Advancing Air-Breathing Propulsion

On January 14, 2026, Lockheed Martin and GE Aerospace announced the successful testing of a liquid-fueled Rotating Detonation Ramjet (RDR). The engine testing was conducted at the GE Aerospace Research Center in Niskayuna, New York.

Unlike steady-state combustion, rotating detonation combustion utilizes continuous detonation waves. This architecture allows the engine to ignite at lower speeds, which reduces the required size of booster rockets and increases available payload capacity. According to technical data released alongside the tests, the RDR system offers an estimated 25% efficiency increase compared to standard rocket propulsion.

“Following two years of internal investment, this demonstration is a testament to the power of collaboration, innovation and joint commitment to get affordable capability into the hands of warfighters at the speed of relevance,”

The statement was provided by Randy Crites, Vice President and General Manager at Lockheed Martin Advanced Programs. Mark Rettig, Vice President and General Manager of Edison Works Advanced Programs at GE Aerospace, added that the testing on the ramjet and inlet exceeded expectations and will serve as a foundation for maturing air-breathing hypersonic propulsion.

Scaling Manufacturing and Advanced Materials

To address the historical expense and complexity of hypersonic vehicles, Lockheed Martin introduced the Next Generation Glide Body (NXGB) on June 24, 2026. The NXGB program is centered in Huntsville, Alabama, and utilizes a manufacturing-first approach to enable rapid scaling. The vehicle is scheduled for its first flight in 2027.

Johnathon Caldwell, Vice President and General Manager of Strategic and Missile Defense Systems at Lockheed Martin, stated that the NXGB was designed from the outset to provide greater value and operational advantage while remaining affordable and producible at scale.

Sustained hypersonic flight requires thermal protection systems capable of surviving temperatures exceeding 2,000 degrees Celsius. On August 10, 2026, Lockheed Martin announced a teaming agreement with Albany Engineered Composites to accelerate the delivery of these critical materials. Chris Stone, President of Albany Engineered Composites, noted that the future of hypersonics depends on more than breakthrough design. He emphasized that the industry requires the ability to manufacture advanced composite structures at unprecedented scale.

We view Lockheed Martin’s 2026 announcements as a clear indicator that the aerospace industry is moving past the fundamental physics of hypersonic flight and into the industrialization phase. The DoD has consistently identified manufacturing bottlenecks and high per-unit costs as primary obstacles to fielding a credible hypersonic deterrent. By investing in rotating detonation architectures and securing composite supply chains through Albany Engineered Composites, Lockheed Martin is directly targeting the efficiency gap that has historically limited hypersonic programs to small-batch experimental flights. The 2027 flight test of the NXGB will be a critical proving ground for whether these manufacturing-first design principles can deliver on their cost and scalability promises.

Lockheed Martin Corporation has unveiled a modular airframe architecture for its AGM-158 cruise missile family, enabling a single core missile design to be launched from air, surface, sub-surface, and ground platforms.

Announced on September 15, 2026, the AGM-158 FLEX airframe utilizes interchangeable nose cones and boat tails to adapt the weapon for different mission profiles. According to a company press release, the design provides military operators with a scalable method to upgrade capabilities and avoid subcomponent obsolescence without requiring separate integration programs for new configurations.

Engineering the FLEX architecture

The FLEX concept centers on standardizing the central fuselage of the missile while allowing the front and rear sections to be swapped based on the launch platform and mission requirements. Lockheed Martin invested $35 million to design and qualify the FLEX airframe concept, a process that included concept development, testing, and prototype production.

The interchangeable nose cones will house the specific sensor suites required for different variants, including the Joint Air-to-Surface Standoff Missile (JASSM) and the Long Range Anti-Ship Missile (LRASM). The removable boat tail section allows the weapon to transition from its traditional air-launched configuration to surface, sub-surface, and ground launch setups.

“We recognized a demand from our customers to have increased options to support their evolving strategic defense and mission needs,” Lockheed Martin stated in the release. “We know no problem or threat exists in a vacuum, and so we innovate with intent, keeping integration in mind and ensuring that our solutions aren’t just new, they’re immediately useful.”

The architecture will support multiple missile lengths depending on the required range and payload:

• 168 inches: The standard extended range option, consistent with the dimensions of the JASSM-ER.
• 206 inches: The extreme range option, designed to support the JASSM-XR configuration.

Manufacturing capacity and defense investment

The introduction of the FLEX airframe aligns with broader efforts by the U.S. Department of Defense (DoD) to increase long-range precision strike capacity. The JASSM-XR variant, which features a 1,000-pound warhead and extreme standoff range, will be the first weapon configuration to utilize the new FLEX architecture.

To support the production of the AGM-158 family at scale, Lockheed Martin opened a 225,000-square-foot intelligent production facility in 2022. The factory incorporates dynamic model forecasting and a fully robotic paint line. The company noted that the modular nature of the FLEX airframe will directly benefit these manufacturing operations.

“The FLEX airframe will provide a modular airframe that gets ahead of subcomponent obsolescence, provides future capability enhancements to outpace threats and enable scalability at the production factory,” the company stated.

The push for scalability follows a $3.2 billion Undefinitized Contract Action awarded to Lockheed Martin in 2024 by the U.S. Air Force and U.S. Navy, aimed at significantly increasing the production capacity for both JASSM and LRASM.

The transition to a modular airframe for the AGM-158 family represents a critical shift in munitions procurement for the DoD. By standardizing the core airframe across air, land, and sea domains, we expect the military to realize substantial logistical efficiencies. Historically, adapting an air-launched cruise missile for a vertical launching system on a surface ship or a submarine torpedo tube required extensive, bespoke engineering efforts that drove up costs and extended development timelines.

The FLEX architecture bypasses this bottleneck. With the JASSM-XR serving as the launch platform for the FLEX design, Lockheed Martin is positioning the AGM-158 family to meet the immediate demand for extreme standoff ranges. This modularity also simplifies the supply chain, allowing the 2022 production facility to churn out a single core airframe that can be customized at the final assembly stage or retrofitted as operational needs dictate.
