China Launches Drones with Modular Truck Catapult

What Happened?

A video published and later removed by the School of Mechanical Engineering at the Beijing Institute of Technology shows three eight-wheeled trucks locking together to form an electromagnetic catapult (EMALS) capable of launching a propeller drone. The system, described as "modular like Lego pieces," is transported in shipping containers and can be deployed anywhere, offering variable launch direction thanks to all-wheel steering. According to TechRadar, the video surfaced late last month and shows the three trucks uncoupled, coupling, and demonstrating all-wheel steering, which in principle allows launching drones or small aircraft in any direction if there is enough space.

Why Is It Important?

Historically, fixed-wing drones require runways or bulky pneumatic/hydraulic catapults. This development miniaturizes the EMALS technology that China already uses on its Fujian aircraft carrier (three catapults) and turns it into a portable ground system. The United States pioneered shipborne EMALS with the USS Gerald R. Ford in 2017 but has not shown a transportable ground version. China is ahead in this variant, which could change the game in asymmetric conflicts and rapid operations. The CSIS analyst cited in the original article notes: "China has turned an aircraft carrier catapult into a system that fits on three trucks. It's a logistical leap that will redefine how drones are deployed on the battlefield."

It is important to contextualize that EMALS technology is not new: the U.S. developed it since the 1990s and integrated it into the USS Gerald R. Ford, which began operations in 2017. However, the U.S. system is designed to launch heavy fighter jets from aircraft carrier decks, with a launch capacity of up to 45,000 kg. China, on the other hand, has adapted the same technology to a smaller scale, reducing size and power to launch lightweight drones. This represents a disruptive innovation because it eliminates the need for fixed infrastructure, enabling rapid deployments on any terrain. In recent conflicts like the war in Ukraine, drones have transformed the battlefield, but their dependence on runways or specific launchers remains a limitation. This portable system could overcome that barrier.

How Does It Work and Who Is Behind It?

The system consists of three trucks: one with the power source and control, another with the linear catapult, and a third that likely acts as support or extension. They lock together to form a launch ramp. More than 70 Chinese state organizations participated in the development, according to analysts. Although the video was removed, its dissemination in defense forums indicates a confirmed technical milestone. TechRadar reports that Chinese state-owned enterprises represent a significant portion of those 70+ organizations directly involved in this achievement, which lays the groundwork for the next generation of drone-based combat. The removal of the video by the Beijing Institute of Technology suggests the development is considered sensitive, but it has not prevented expert analysis.

The operating principle is similar to naval EMALS: a magnetic field generated by electric currents accelerates a carriage along a rail, propelling the aircraft. The key difference here is portability: the trucks carry diesel generators (likely) and capacitors that store the energy needed for launch. Each eight-wheeled truck has all-wheel steering, allowing the catapult to be aligned in any direction without moving the entire assembly. This is a significant tactical advantage, as it allows launching drones into the wind or toward a specific target without repositioning the whole system.

Strategic Consequences

Portability allows launching reconnaissance or attack drones in minutes from anywhere: deserts, mountains, or urban areas. It reduces dependence on fixed air bases, which are vulnerable to preemptive strikes. It could also be used to launch drone swarms in coordinated missions. Geopolitically, it accelerates the EMALS race among powers: France and India also plan naval EMALS, but China already has a ground option. This development could force the U.S. and its allies to accelerate similar programs. Additionally, the ability to launch drones without a runway changes military logistics: a convoy of trucks can set up a temporary launch base anywhere, which is especially relevant in high-mobility wars like those in the Indo-Pacific, where islands and atolls lack airport infrastructure.

In terms of deterrence, China demonstrates that it can deploy drone strike capabilities quickly and covertly. Such a system could be used to saturate air defenses with drone swarms launched from multiple directions. According to military analysts, the ability to launch drones in any direction without turning the entire system allows attacks from unexpected angles, increasing effectiveness. It could also integrate with artificial intelligence systems to coordinate launches in real time.

Commercial and Technological Implications

Beyond military use, the modularity and use of commercial trucks could inspire civilian applications: launching cargo drones in remote areas, disaster response, or deploying emergency communications. Miniaturized EMALS technology could find a market in logistics and defense. For example, logistics companies like Amazon or DHL could use similar systems to launch cargo drones in areas without infrastructure, though regulations and cost would be barriers. In disaster response, these systems could launch reconnaissance or supply delivery drones in minutes, without needing runways. However, the current cost of the system is likely high, given the advanced electromagnetic components and energy storage. As the technology matures and is mass-produced, costs could decrease, opening civilian applications.

From a technological standpoint, the system demonstrates China's ability to miniaturize high-performance technologies. The integration of modified commercial trucks suggests a low-cost approach compared to dedicated systems. This could inspire other countries and companies to develop modular launchers. Additionally, all-wheel steering is a feature that could be applied to other military and civilian vehicles, improving maneuverability on difficult terrain.
