Opinion | 'Hellish Difficulty': Why India Should Be Keeping An Eye On China's New 'Shipborne' Drone

On April 30, an unofficial photograph began circulating in Chinese-language military fora, showing in flight a stealth drone with a flying-wing design, its landing gear deployed, and a small metal rod jutting from its nose strut. It was subsequently revealed to be the naval variant of China's GJ-11 "Sharp Sword" combat drone - the GJ-21 shipborne UAV. It is produced by Hongdu Aviation, a subsidiary of one of China's largest defence State-Owned Enterprises (SOEs) - the Aviation Industry Corporation of China (AVIC).

The GJ-21 has evolved over a decade. Its predecessor, the GJ-11, was first unveiled at the 70th National Day parade in 2019 in Beijing. In November 2025, it was officially codenamed "Xuanlong" (Mighty/Mysterious Dragon) in a mini-film, and subsequently also goes by the name 'Sharp Sword'. It has been one of the most prominent land-based UCAV systems in China's arsenal and was also paraded in Tiananmen Square during the 2025 September 3 military parade. 

Problem Of 'Hellish Difficulty'

The UCAV has adapted its predecessor's tailless flying-wing design, and expanded on it for catapult launch and arrested recovery. Chinese commentary has dramatically called it a problem of "hellish difficulty." Because a carrier's deck is relatively short compared to a regular runway, a catapult launch enables a drone to take off at cruise speed with great ease. In 2021, a Beijing-based analyst, Li Jie, informed that the Type 076 amphibious assault ship would be equipped with electromagnetic launch capability for jet-powered UCAVs. The April 30 photographs close the loop on that front.

Today, the GJ-21 is conducting trials alongside new launch platforms that are designed to deploy the UAV as a core combat system. One is the Type 076 Sichuan, unveiled in December 2024, and which is currently in its third sea trial. It is an amphibious assault ship with a 40,000-tonne displacement, is purpose-built for stealth UCAVs, and is fitted with one electromagnetic catapult and three arresting wires. As opined by Chinese military analyst Song Zhongping, there could be up to 19 GJ-21s on the deck. Another platform is the Type 003 Fujian, China's first indigenous carrier. It was commissioned into active duty in November 2025, and has previously conducted exercises in the Bohai Sea alongside J-15T fighters, J-35 stealth fighters, and KJ-600 early-warning aircraft. It could subsequently integrate the GJ-21 as a "loyal wingman," and spring Human-Machine Team (HMT) into action.

Why More Drones?

The hints to China's military modernisation trajectory are embedded in its key doctrinal texts. One such text is the PLA Academy of Military Sciences' 2020 Science of Military Strategy. It explicitly highlighted that carrier-based UAVs are a "transformative capability" that would alter "carrier-based aircraft take-off and landing methods, and carrier-based aircraft structure." This operational emphasis has become increasingly relevant in the Chinese military's transition to a force capable of multi-domain, integrated joint operations, and the GJ-21 fits squarely within this post-reform combat architecture.

There are two main takeaways from the deployment of the stealth UCAV. Firstly, it alters the cost-benefit calculus of sea-based airpower for China. As the GJ-21 likely costs a little over US$ 30 million, when compared with the cost of a J-35, which can go up to US$ 80 million, or even the cost of a sea-based variant of a J-15 jet - ~US$ 60 million - there are clear advantages in mass production and deployment. Second, there is the long-range capability. The GJ-21, which has a reported combat attack radius of up to 1,500 kilometres, when combined with a land-attack long-range precision-strike system, can have the ability to strike deep within a territory's mainland.

What is notable for India is that the land-based GJ-11 was imaged at the Shigatse air base in Tibet in 2025, at an altitude of 3,800 metres. The lineage of the G-21 is already in service in the PLA Western Theater Command, and it is now likely to be deployed in the South China Sea. The structural constraints the Chinese ecosystem faces, which revolve around limitations to autonomous, AI-enabled control and engine performance, as well as the inability of PLA personnel to consistently adapt to new technologies, are indeed real. Further, AVIC, the SOE responsible for its design and maintenance, has had its last two Chairmen - Tan Ruisong and Zhou Ximin - dismissed on corruption and rigging charges. And yet, for a military force aiming to become expeditionary and world-class in the coming decade, its newest inductions must be watched keenly in India.
