The 15th China International Aviation and Aerospace Exhibition, commonly known as Airshow China, has once again positioned itself as a pivotal platform for showcasing cutting-edge military technology. Held in Zhuhai, Guangdong Province, the biennial event not only presented new achievements in aviation and aerospace but also unveiled advances across land, sea, and electronic information domains.
Among the array of high-tech innovations, the spotlight shone brightly on the debut of the “Orca” unmanned surface combat vessel, a groundbreaking development that has drawn significant attention both domestically and internationally.
Naval Technology: “Orca” Debut
The “Orca” unmanned combat vessel represents a major leap in maritime warfare technology. Measuring 58 meters in length, 23 meters in width, and with a depth of 4 meters, the vessel boasts a displacement of 500 tonnes. Its diesel-electric dual-mode propulsion system delivers impressive performance, achieving speeds of up to 40 knots (74 km/h) and a remarkable range exceeding 4,000 nautical miles (7,400 km). This combination of speed, endurance, and stealth makes the “Orca” a versatile and formidable presence on the seas.
The vessel was developed at a record pace, moving from its first sea trial in 2022 to its public debut in just two years. This rapid timeline underscores China’s growing expertise in overcoming technical challenges related to unmanned naval platforms, modular systems, and autonomous operational capabilities. According to military analysts, the “Orca” signifies China’s push into the “realm of freedom” in unmanned vessel design, where the integration of advanced technologies eliminates traditional constraints.
Redefining Naval Operations
The “Orca” offers a glimpse into the future of naval operations. As an unmanned combat platform, it removes the limitations imposed by human physiological needs, enabling sustained high-intensity missions on the open sea. This autonomy allows personnel to focus on strategic tasks while the vessel undertakes routine or high-risk missions. The potential applications of the “Orca” range from low to medium-intensity operations, such as patrolling strategic maritime chokepoints, guarding key waterways, and securing offshore installations.
“Orca”
The “Orca” is defined by three prominent features that set it apart in the domain of unmanned surface vessels (USVs):
-
Large Tonnage and Modularity
The “Orca” displaces 500 tonnes, allowing it to integrate capabilities typically reserved for larger manned surface vessels. Its size provides exceptional endurance, stability, and wave resistance, critical for long-duration missions in challenging sea conditions.
- Combat Systems: The vessel is equipped with four phased array radars and a general-purpose vertical launching system, enabling it to deploy rockets, anti-ship missiles, air defense missiles, and remote-control weapon systems.
- Integration with Drones: It supports operations with the Z-5B/G unmanned helicopter, enhancing reconnaissance, targeting, and strike coordination.
- Payload Flexibility: A docking bay at the stern facilitates the deployment of underwater devices, sonobuoys, radar buoys, and other detection sensors.
-
Stealth Capability
Stealth is a critical aspect of the “Orca” design. Its advanced radar-wave stealth features reduce its detectability, granting it an edge over traditional ships and patrol aircraft. These capabilities are vital for operations requiring concealment and surprise, ensuring the vessel can approach targets undetected or evade enemy detection systems.
-
Dynamic Structure and Propulsion
The “Orca” adopts a trimaran hull structure, renowned for its stability and efficiency in turbulent seas. This design, coupled with its diesel-electric dual-mode propulsion system, ensures the vessel can operate quietly in low-noise modes or transition to high-speed pursuits as needed. Such versatility enhances its ability to evade threats or respond rapidly to emerging situations.

Transforming Maritime Combat Scenarios
The “Orca” is more than just an unmanned vessel; it represents a paradigm shift in maritime strategy. By removing human operators from direct risk and leveraging artificial intelligence, the vessel introduces new possibilities for combat, surveillance, and strategic dominance. Below are some of the significant operational roles envisioned for the “Orca”:
- Beyond Visual Range (BVR) Fire Strike
Equipped with advanced targeting systems and weaponry, the “Orca” can engage targets well beyond the line of sight. This capability enables it to support fleet operations or act as a forward-deployed asset, striking adversaries before they become a threat. - Air and Missile Defense
With its phased array radars and vertical launch systems, the “Orca” can detect and intercept incoming aerial and missile threats, providing a robust layer of defense for naval formations or strategic installations. - Anti-Submarine Operations
The vessel’s ability to deploy underwater devices, such as sonobuoys and anti-submarine torpedoes, makes it a formidable tool for countering submarine threats. Its stealth capabilities further enhance its effectiveness in anti-submarine warfare (ASW) missions.
The unveiling of the “Orca” reflects China’s broader ambitions to enhance its naval capabilities and establish dominance in maritime technology. By prioritizing unmanned systems, China aims to achieve the following strategic objectives:
Unmanned vessels like the “Orca” enable naval forces to cover greater areas with fewer personnel. This force-multiplication effect allows for expanded operational reach without proportional increases in resource allocation.
In high-stakes or hazardous environments, unmanned vessels reduce risks to human operators, ensuring critical missions can be carried out without jeopardizing lives.
The “Orca” represents a step toward fully autonomous naval operations, where AI-driven vessels coordinate seamlessly with manned ships, aircraft, and ground forces to execute complex missions.
The “Orca” has generated significant interest and concern among global military observers. The vessel’s capabilities highlight China’s intent to challenge traditional naval powers and redefine the dynamics of maritime security. Analysts have noted parallels between the “Orca” and similar projects pursued by the United States and other advanced militaries, emphasizing the escalating competition in unmanned naval technology.
Countries with critical maritime interests are likely to view the “Orca” as both a technological marvel and a strategic challenge. Its ability to operate autonomously and perform a wide range of missions could influence the deployment strategies of naval forces worldwide.
