The PLA's Drone Swarm Strategy Accelerates Formation: Multidimensional Breakthroughs from the Atlas System to the J-6W Modified Drone

Spring 2026, the People's Liberation Army of China is exhibiting an unprecedented acceleration in the field of unmanned combat systems. From the "Atlas" swarm drone system publicly revealed by CCTV on March 25, to the more than 200 retired J-6 fighter jets being converted into J-6W attack drones disclosed by Reuters on March 27, and the live-fire training exercises conducted by the Eastern Theater Command's naval destroyer fleet in the East China Sea, multiple clues point to a clear direction of military transformation: the PLA is constructing a multi-layered, large-scale, intelligent unmanned combat system, with the core objective of possessing the capability to overwhelmingly breach advanced air defense systems in future Taiwan Strait conflicts.

The strategic logic behind this transformation is rooted in the PLA's long-standing concept of a "revolution in military affairs" centered on "intelligence." In 2020, Xi Jinping, Chairman of the Central Military Commission, established intelligence as an important priority for military modernization, and the "Strategic Studies" published that year explicitly referred to intelligence as a "new military revolution," calling for the development of intelligent unmanned systems. The U.S. Department of Defense's 2023 assessment also pointed out that China is prioritizing the development of AI autonomous capabilities for unmanned systems. Within this framework, the PLA has been laying out swarm technology patents since 2009, and after more than a decade of technological accumulation, it has now entered the stage of practical deployment.

The public debut of the "Atlas" swarm system is the latest milestone in this process. According to the Global Times, each "Atlas" launch vehicle can deploy 48 drones, while a single command vehicle can coordinate 96 drones to execute collaborative tasks simultaneously. Footage released by CCTV shows that the system has already conducted actual formation training. Notably, a commentary article published by the PLA Daily at the same time cited real combat cases from the militaries of Ukraine, Russia, the United States, and Israel, emphasizing the urgency of developing AI autonomous unmanned capabilities—especially on the Ukrainian battlefield, where electronic warfare methods have shown increasingly strong suppression effects on traditional drones, and autonomous swarms are seen as a key solution to break through electronic warfare interference.

From a technical perspective, the "Atlas" system represents a unique branch of the PLA's drone development. Unlike large fixed-wing drones such as the Wing Loong-2, Attack-11, and Rainbow-4—which are designed more similarly to the U.S. MQ-9 Reaper drone, focusing on long-endurance reconnaissance and precision strikes—the swarm system follows a completely different "low-cost saturation attack" route. Its operational concept is to use the coordinated actions of a large number of low-cost drones to exhaust and overwhelm the opponent's air defense system's interception capabilities, creating conditions for subsequent precision missile strikes and amphibious landings.

Even more noteworthy is the J-6W modified drone project. According to a report from the Mitchell Institute for Aerospace Studies, by 2026, over 200 retired J-6 fighter jets have been converted into unmanned attack aircraft, deployed at at least five air force bases in Fujian and one base in Guangdong. The J-6 is derived from the Soviet MiG-19 fighter jet from the 1950s; although technically outdated, it has unique advantages when converted into a drone: its jet propulsion allows it to achieve speeds and payload capacities far exceeding those of small drones, and with the addition of an onboard automatic flight control system, it can be used as a one-time long-range attack weapon. The scale of 200 means that when a conflict in the Taiwan Strait breaks out, the PLA can be the first to launch this batch of "suicide" drones to saturate attack Taiwan's air defense network without consuming expensive active equipment.

From a broader perspective, the current PLA drone strategy exhibits a clear "high-low mix" characteristic. The high-end route is represented by the "Sky Mother" unmanned mothership—reportedly capable of coordinating 100 small drones to execute tasks, positioned as a battlefield air command node; the low-end route is represented by the "Atlas" swarm and J-6W, pursuing large-scale, low-cost saturation attack capabilities. The combination of the two forms a network covering unmanned combat from the tactical to the operational level.

However, this strategy is not without concerns. A special research report jointly released by the American Enterprise Institute (AEI) and the Institute for the Study of War (ISW) on April 6 pointed out that the PLA's process of drawing lessons from the conflicts in Ukraine and the Middle East is profoundly shaped by its existing "intelligence" concepts and established military production plans. The report suggests that the PLA's long-term investment in AI swarm technology and large precision reconnaissance drones may lead to selective bias in interpreting contemporary conflicts—tending to absorb experiences that confirm its existing judgments while ignoring or underestimating other equally critical lessons. Specifically, the "low-cost attrition warfare" model demonstrated on the Ukrainian battlefield is not only about technological advancement but also about large-scale industrial production capacity, sustained logistical support, and flexible tactical adaptability. If the PLA overly focuses on high-tech swarm systems, it may overlook these more fundamental elements of warfare.

Taiwan is also not sitting idly by. In October 2025, Taiwanese President Lai Ching-te proposed the "T-Dome" air defense concept, aiming to build a comprehensive air defense and missile defense network. The $40 billion "asymmetric warfare special budget" promoted by the DPP government includes plans to procure 200,000 unmanned systems and funding to develop Taiwan's domestic military industry. However, the obstruction by the Kuomintang and the People First Party in the Legislative Yuan has stalled this budget, agreeing only to about $12 billion without including large-scale drone procurement and air defense network construction funds. This political deadlock is affecting Taiwan's progress in procuring conventional weapon systems from the United States, such as the HIMARS multiple rocket system, M109A7 self-propelled howitzer, and "Tao" and "Javelin" anti-tank missiles. The U.S. State Department has agreed to extend Taiwan's payment deadline to May 2026 as of March 30.

Meanwhile, the PLA's military activity patterns around the Taiwan Strait have also shown subtle changes. According to monitoring data released by Taiwan's Ministry of National Defense, the number of PLA aircraft circling Taiwan has shown a continuous downward trend in recent months. On April 11, Taiwan detected 17 instances of PLA aircraft, 7 naval vessels, and 1 civilian ship operating around the Taiwan Strait, with 15 instances crossing the median line of the strait into Taiwan's air defense identification zone in the northern and southwestern regions. ISW analysis suggests that the reduction in sorties may indicate that Beijing is adjusting its coercive strategy towards Taiwan—previously high-frequency incursions into the air defense identification zone, while having a deterrent and pressure effect, have seen diminishing marginal returns over time. Reducing the number of sorties around Taiwan can free up PLA resources for other training tasks, while also allowing for the potential to resume large-scale circling operations when needed in the future, thereby resetting its deterrent effect.

In summary, the development of the PLA's unmanned combat system in the spring of 2026 presents clear systemic characteristics: technologically evolving from a single platform to a networked swarm, strategically transforming from an auxiliary role to a main combat force, and tactically expanding from reconnaissance and strikes to saturation attacks. This transformation will have profound implications for the security landscape in the Indo-Pacific region. For Taiwan and its security partners, how to accelerate the construction of air defense networks and the development of unmanned system capabilities amid political infighting will directly determine the future trajectory of military balance in the Taiwan Strait.
