General Atomics Aeronautical Systems, Inc. (GA-ASI), in collaboration with South Korea’s Hanwha Aerospace, has achieved a significant milestone with the Gray Eagle STOL (Short Takeoff and Landing) Unmanned Aircraft System (UAS).
On November 12, 2024, the Gray Eagle STOL successfully launched from the South Korean Navy’s amphibious landing ship Dokdo and completed its flight with a smooth landing at Pohang Navy Airfield.
This event marked the first ship-to-land mission for this type of aircraft, further showcasing the UAS’s operational versatility for multi-domain environments.
Gray Eagle STOL Overview
Gray Eagle STOL is a medium-altitude, long-endurance UAS uniquely designed for short takeoff and landing capabilities. It operates from large-deck naval vessels, including amphibious ships and aircraft carriers, and is equally suited for land-based operations from short or unimproved airfields.
This demonstration with the Republic of Korea Navy highlights its adaptability to a variety of mission scenarios, providing significant strategic value without requiring costly modifications to existing warships.
Advanced Maritime Integration
GA-ASI CEO Linden Blue highlighted the significance of this milestone saying, “We applaud the South Korean navy for its foresight in examining the unique capability of GE STOL for its fleet. This demonstration illustrates the ability of the GE STOL to safely operate on many types of aircraft-capable ships, which opens myriad new ways our allies can use this UAS to support multi-domain naval operations.”
Hanwha Aerospace is engaged with General Atomics to support national defense with proven, state-of-the-art technology suited for a multi-domain warfare environment, contributing to global security alongside allied nations in response to rapidly growing threats.
“The demonstration is a crucial step in verifying how the GE STOL can contribute to defense capabilities, and I am honored to witness this alongside the Republic of Korea Navy, to whom I extend my deepest gratitude for conducting the test,” said Hanwha Aerospace CEO and President Jae-il Son. “Hanwha is fully committed to making bold investments, fostering collaboration, and providing steadfast support in the Unmanned Aerial Vehicle (UAV) business.”
Testing and Evaluation
The Ministry of National Defense for the Republic of Korea is initially evaluating GE STOL for its ability to meet its emerging military requirements. South Korean navy, army and other officials were asked to evaluate Gray Eagle STOL and supported the test.
“The demo highlighted the versatility of STOL aboard a warship, in the Dokdo, designed not for fixed-wing aircraft but solely for helicopters. Gray Eagle STOL’s flight proves that navies can add significant new capability without costly major modifications to their existing warships,” said South Korean Chief of Naval Operations, Admiral Yang Yong-mo.
Proven Performance History
Gray Eagle STOL is highly common with the classic Gray Eagle aircraft, substituting a different engine, wings, control surfaces and landing gear. Gray Eagle STOL is General Atomics’ name for the production variant of the historic aircraft demonstrator known as Mojave.
In November 2023, GA-ASI and Mojave performed a demonstration of STOL takeoff and return landing aboard an aircraft carrier in an event with the UK Royal Navy’s HMS Prince of Wales, which is smaller than a typical U.S. aircraft carrier at 932 feet long (284m) and 240 feet wide (73m). The Dokdo class is considerably smaller than the Prince of Wales, only 653 feet long (199m) and 102 feet wide (31m).
