China is developing the GJ-11 Sharp Sword stealth drone to accompany its J-20s and J-35s. Capabilities, deployment, and the challenges of autonomous air combat.
In Summary
China is accelerating the development of its stealth combat drones with the GJ-11 Sharp Sword, a flying wing designed for reconnaissance and deep strikes. After more than a decade of development, the aircraft is entering an advanced operational testing phase.
Three GJ-11s were observed at an airbase in Tibet in 2025. A few months later, the People’s Liberation Army Air Force (PLAAF) released the first footage of the drone flying with a J-20 fighter and a J-16D electronic warfare aircraft. Its naval variant, the GJ-21, is also continuing its trials in 2026.
Beijing is now seeking to integrate autonomous drones with its J-20 and J-35 stealth fighters to penetrate adversary defenses and multiply strike capabilities. However, despite these advancements, no public data yet confirms mass production of the GJ-11 or its deployment in large-scale combat units.
The GJ-11 Sharp Sword Marks a New Step in Chinese Military Aviation
China is no longer just seeking to build stealth fighters capable of rivaling American aircraft. It is now developing combat systems combining piloted aircraft, autonomous drones, and electronic warfare.
The GJ-11 Sharp Sword, also called Xuanlong, occupies a special place in this strategy. Developed by Hongdu Aviation Industry Group and Shenyang Aircraft Design Institute within the Aviation Industry Corporation of China (AVIC) ecosystem, it belongs to the category of heavy stealth combat drones.
Its development dates back more than a decade. A first demonstrator flew in November 2013. A heavily modified configuration was publicly presented during the Beijing military parade in 2019.
The program primarily targets the penetration of adversary air defenses, reconnaissance, and precision strikes. Unlike conventional drones used in undefended environments, the GJ-11 is designed to operate against modern radars and anti-aircraft systems.
Flying Wing Design Prioritizes Stealth and Autonomy
The GJ-11 adopts a tailless architecture, comparable in principle to that of the American B-2 Spirit bomber or the former X-47B naval demonstrator.
Its wingspan is generally estimated at around 14 meters (46 feet). Its length is believed to be close to 12 meters (39 feet). These dimensions remain indicative: China does not publish a complete technical data sheet to confirm the performance of current versions.
Reduction of Radar and Infrared Signatures
The absence of vertical stabilizers limits the surfaces likely to reflect radar waves. The shapes are designed to control reflection directions, while armaments are carried in internal bays.
The engine exhaust has also been redesigned to limit radar and infrared signatures. The latter remains essential: an aircraft difficult to detect on radar can still be spotted by thermal sensors.
Stealth therefore does not mean invisibility. It reduces the distances at which an aircraft can be detected, tracked, and engaged.
The GJ-11 prioritizes this discretion over the maneuverability performance of a supersonic fighter.
Its exact speed, operational range, and payload characteristics remain unknown. Figures sometimes put forward, notably an endurance of several thousand kilometers or a 2-ton payload, do not constitute officially verified performance.
GJ-11 Deployment Progresses Without Proof of Mass Production
In October 2025, The War Zone revealed satellite imagery showing three GJ-11s at Shigatse airbase in Tibet between August 6 and September 5.
This facility is located at an altitude of approximately 3,782 meters (12,410 feet). It features a 5,000-meter primary runway and a 3,000-meter secondary runway.
These infrastructures notably allow aircraft to be tested in low atmospheric density conditions, which penalize engine performance and lift.
The presence of the GJ-11s suggests an operational evaluation phase, beyond the Malan test facilities where the aircraft had previously been observed.
However, no reliable public inventory makes it possible to quantify the fleet. The images confirm a point deployment, not several hundred aircraft in service.
This distinction is essential for assessing the PLAAF’s actual level of readiness.
The J-20 Becomes the Preferred Partner for Combat Drones
On November 11, 2025, Chinese state media released video footage showing a GJ-11 flying with a Chengdu J-20 and a J-16D specialized in electronic warfare.
This demonstration illustrates the concept of cooperation between piloted and unpiloted aircraft, known as Manned-Unmanned Teaming.
In an operational configuration, the J-20 could identify targets and coordinate multiple drones tasked with conducting reconnaissance, jamming radars, or carrying armaments.
The J-16D would provide a complementary capability for detecting electromagnetic emissions and jamming.
The two-seat J-20S is of particular interest. Its second crew member could supervise multiple drones without overloading the pilot tasked with the air mission.
In June 2026, the US Air Force’s China Aerospace Studies Institute estimated that China’s 9th Aviation Brigade had been participating since 2024 in validating tactics combining fighters and drones.
However, the published footage demonstrates neither the number of drones controllable simultaneously nor their actual autonomy in a jammed environment.
The J-35 Opens the Prospect of Combined Naval Aviation Operations
The Shenyang J-35 and its land-based variant J-35A are set to complement China’s fleet of stealth fighters.
The J-35 is intended for naval aviation, while the J-35A meets PLAAF needs. Their future integration with stealth drones would extend their detection and attack capabilities.
However, unlike the J-20, no equivalent public demonstration has established operational cooperation between the J-35 and the GJ-11.
The GJ-21 Prepares the Projection of Stealth Drones from the Sea
The naval variant of the GJ-11, designated GJ-21, features adaptations for carrier-based operations, notably folding wings, an arrestor hook, and a catapult launch system.
In 2026, several photographs showed aircraft exhibiting these characteristics. Videos released in August also documented flight tests near Huludao.
The future Type 076 Sichuan amphibious assault ship, of approximately 40,000 tons, features a flight deck measuring 250 by 62 meters and an electromagnetic catapult.
It could employ GJ-21s to conduct remote reconnaissance and strikes. Nevertheless, integration trials remain distinct from a confirmed embarked operational capability.
Artificial Intelligence Constitutes the Main Operational Challenge
The success of these programs depends as much on software as on aerodynamic performance.
A penetration drone must be able to follow a trajectory, process sensor data, and react to unforeseen events when communications are degraded.
Artificial intelligence could facilitate threat identification, route selection, and mission distribution among multiple aircraft.
But the difficulties remain considerable: resistance to jamming, algorithm reliability, link security, and human control over engagement decisions.
A formation demonstration does not prove that a drone can accomplish these tasks in combat.
Chinese Industrial Power Shifts the Regional Air Balance
Financial effort allows Beijing to conduct multiple programs simultaneously.
In 2026, China projects 1.940 trillion yuan in national defense spending, or approximately $282 billion, representing a 6.9% increase. No specific amount for the GJ-11 has been published.
According to the Royal United Services Institute, the Chinese fleet reached approximately 320 to 350 J-20s at the end of 2025, with an estimated production rate of 120 fighters per year. These evaluations are not official Chinese figures.
The combination of numerous modern fighter jets and penetration drones could complicate Taiwan’s defense and US air operations in the Western Pacific.
Facing American Collaborative Combat Aircraft programs, China is relying in particular on stealth drones capable of carrying out prolonged deep missions.
The main challenge will not be producing the greatest number of aircraft. It will be demonstrating that fighters, drones, sensors, and electronic warfare assets can function as a cohesive whole.
The GJ-11 reveals an ambitious transformation of Chinese military aviation. Its true strategic value will appear when Beijing is capable of demonstrating complex, repeatable operations that are resistant to modern defenses. For now, industrial progress is visible, but operational maturity remains difficult to establish.
