China has introduced a new close-in defense system dubbed the “Bullet Curtain,” designed to counter drone swarms and incoming high-speed missiles. Developed by the state-owned defense contractor Norinco, the system is being hailed as the world’s first of its kind, according to a report by the South China Morning Post published Friday (April 11).
Unlike conventional anti-air systems that aim to neutralize targets with pinpoint accuracy, the Bullet Curtain uses a “plane-to-point” interception strategy. This approach involves unleashing a dense wall of overlapping projectiles to blanket the airspace, thereby increasing the probability of neutralizing multiple airborne threats simultaneously.
High-tech interception with integrated detection and fire control
Equipped with radar, optical detection, a fire-control system, integrated management modules, and an onboard ammunition supply, the Bullet Curtain combines modern tracking with high-speed firing capabilities to detect and destroy its targets.
“Imagine the target is a fly. The traditional air-defense interception is like throwing stones at the fly continuously … and now the barrage system is like swinging a fly swatter, which covers the entire area where the fly may move,” said Yu Bin, chief designer of the system.
“While traditional air-defense weapons only hit at a single point, we are building a canopy capable of countering a saturation attack,” he added.
According to Norinco, the Bullet Curtain draws conceptual inspiration from Metal Storm—a rapid-fire, electronically controlled weapon project developed jointly by Australia and the United States in the late 1990s. Unlike its predecessor, which never moved beyond the prototype stage, Yu claims Norinco’s version is a functional, deployable solution with enhanced effectiveness and affordability.
Dense firing matrix and modular configuration
The system reportedly features a 4×4 array of 35mm gun barrels, designed for multiple ammunition types, including advanced hit efficiency and destruction (AHEAD) rounds. Each round releases hundreds of sub-projectiles, creating a lethal zone of impact capable of disrupting small drones and larger aerial threats.
Yu revealed that the team had also developed a new form of “serial and parallel ammunition” to intercept faster, larger targets such as incoming missiles.
The entire system is mounted on a 6×6 truck, giving it road mobility and allowing it to be embedded within mechanized units. Thanks to its modular architecture, it can also be integrated with a variety of platforms—from wheeled and tracked armored vehicles to naval ships and static installations—enabling flexible deployment in a wide range of combat environments.
AI-driven adaptive targeting for dynamic threats
A key strength of the Bullet Curtain lies in its adaptability. According to Yu, the barrage’s size, shape, and pattern can be optimized in real time through computer-assisted decision-making.
“The size and type of the barrage could be adjusted by computer based on the characteristics of the incoming target, to determine which strategy is to be used and the best way to strike it,” Yu explained. “That is the most significant highlight of this weapon system.”
Live-fire testing validates the system against drone swarms
Norinco’s system has undergone multiple live tests demonstrating its effectiveness against swarming drone attacks—a growing concern in modern warfare. Drone swarms are not only difficult to detect and intercept but also capable of overwhelming traditional air defense systems due to their sheer numbers and low operational costs.
In such a scenario, adversaries can use inexpensive drones to drain the firing capacity of expensive missile systems. The Bullet Curtain, according to Yu, is built to flip this equation by offering a low-cost, high-efficiency solution capable of defending large areas from simultaneous multi-target attacks.
“There is an urgent need for an anti-drone weapon that is capable of locking onto and tracking a number of targets at the same time, and of carrying out simultaneous multi-point or area coverage strikes on a number of targets, thus accomplishing massive destruction of drone swarms in the shortest possible time,” Yu said.
“And this barrage weapon, with low-cost, high-efficiency regional air-defense capabilities … is the much-needed air defense system,” he added.
