The Gray Eagle STOL UAS is engineered to deliver medium-altitude, long-endurance performance with a unique emphasis on operational runway independence. Unlike many traditional UAS platforms, the GE STOL is capable of taking off and landing on semi-improved surfaces such as dirt roads, fields, and even naval vessels, without the need for specialized catapults or arresting gear. This design attribute significantly expands deployment options and operational reach. The demonstrator variant, known as Mojave, has already undergone notable trials, including a successful operation from a dirt strip and a landmark flight from the South Korean Navy’s amphibious landing ship, ROKS Dokdo, in 2024. These demonstrations underscore the platform’s adaptability in multi-domain operations, supporting missions ranging from intelligence, surveillance, and reconnaissance (ISR) to direct attack roles.
With a payload capacity of 1.6 tonnes, the Gray Eagle STOL can be configured for a variety of mission profiles. Its flexibility is expected to appeal to a broad spectrum of military customers seeking to enhance their operational agility and reduce dependency on fixed infrastructure.
“Co-producing GE [Gray Eagle] STOL in South Korea and the U.S. will create jobs and help Hanwha secure talent in related fields as well as foster our domestic (Korean) UAS industry ecosystem.”
— Jae-il Son, President and CEO, Hanwha Aerospace
The agreement, finalized at the Association of the US Army (AUSA) conference in October 2025, outlines a comprehensive plan for co-development and co-production of the Gray Eagle STOL UAS. A central component of this plan is the establishment of a dedicated production facility in South Korea, which will handle final assembly and manufacturing. GA-ASI will oversee the final integration of mission systems, ensuring that both companies contribute their core competencies to the project.
Initial production will be distributed between GA-ASI’s facilities in California and Hanwha’s facilities in South Korea, allowing for knowledge transfer and the establishment of robust manufacturing processes. This approach is designed to expedite the ramp-up to full-scale production and support timely delivery to customers.
The partnership specifically targets a global customer base, with the U.S. Department of Defense and the South Korean Ministry of National Defense identified as primary clients. The first flight of a production-representative Gray Eagle STOL is scheduled for 2027, with initial deliveries planned for 2028.
The global unmanned aircraft systems market is experiencing rapid growth, with projections estimating its value to reach 5 trillion KRW by 2040. GA-ASI has identified a potential demand for over 600 Gray Eagle STOL units within the next decade, which could translate into approximately 15 trillion won in revenue over that period.
Hanwha Aerospace has committed to investing more than 750 billion KRW in the development and production facilities for the GE STOL and its engines. Of this, 300 billion KRW will be sourced through a share offering, underlining the scale and seriousness of Hanwha’s commitment to the project. Beyond direct financial returns, the partnership is anticipated to generate significant economic benefits for South Korea, including job creation, skills development, and the strengthening of the domestic UAS industry ecosystem. It also positions Hanwha as a key player in the global UAS supply chain.
“Hanwha Aerospace views unmanned systems as a strategic pillar for the future of defense. Through our collaboration with GA-ASI, we aim to strengthen sovereign defense capabilities, expand Korea’s presence in the global UAS market, and contribute to a more robust ROK-US alliance.”
