PLA Drone Tactics Exposed: New Concepts for First Island Chain Blockade and Insights on Low-Cost Kill Chains

The People's Liberation Army Navy is brewing a brand new blockade tactic, the core of which is not traditional naval formations or air power projection, but rather bringing unmanned mine-laying systems to the forefront. According to an analysis article in the latest issue of the Chinese military journal "Shipborne Weapons," the PLA may utilize the AJX002 underwater unmanned platform to carry out offensive mine-laying missions, targeting key maritime passages around the Ryukyu Islands of Japan and the Philippine Sea, directly aimed at the first island chain. The timing of this concept's disclosure is quite delicate—coinciding with the U.S. implementing blockade operations against Iranian ports this week and the tense situation in the Strait of Hormuz, the vulnerability of strategic waterways has once again become the focus of global military discussions.

The analysis article clearly states that in the scenario of a conflict in the Taiwan Strait, the PLA has no need to deploy mines around Taiwan Island, as the People's Liberation Army already possesses the capability to quickly establish a comprehensive blockade system to isolate Taiwan Island using land-based missiles, air power, submarines, and aircraft carrier battle groups. This judgment actually responds to recent speculations from several U.S. think tanks regarding the possibility of the PLA implementing a mine blockade against Taiwan, but it offers a bolder alternative: shifting the focus of mine-laying operations from the waters near Taiwan to the outer side of the first island chain, directly intercepting the supply lines and troop deployment channels of intervention forces from the U.S. and Japan.

The AJX002 unmanned platform has previously been reported as a significant breakthrough in China's military unmanned underwater systems, being evaluated as a disruptive and intelligent new equipment. Its application in offensive mine-laying missions means that the PLA is expanding the role of unmanned systems from traditional reconnaissance and surveillance to proactive maritime combat operations. The deeper logic behind this tactical shift lies in the significant optimization of cost-effectiveness: compared to traditional surface ship mine-laying or aerial mine-laying, the deployment of unmanned underwater platforms carries lower risks, greater concealment, and the ability to operate continuously within the blind spots of enemy anti-submarine patrols. Once minefields are established in the deep-water channels between the Ryukyu Islands and the Philippines, it will force any foreign naval formations attempting to pass through to spend a considerable amount of time conducting mine-sweeping operations, thereby granting the PLA a critical tactical window.

It is noteworthy that this tactical concept resonates interestingly with the low-cost precision strike trend currently observed on the battlefield in the Middle East. Within the same week, Chinese CCTV military commentator Zhang Xuefeng provided a detailed analysis of the performance of Iran's 358-type cruise interception missile in actual combat. This weapon system, codenamed SA-67, weighs only about 50 kilograms, uses a micro turbojet engine and solid rocket booster, has a cruising speed of approximately 0.6 Mach, a range of 100 to 150 kilometers, and is equipped with an infrared guidance system. Although its subsonic flight characteristics make it difficult to counter jet fighters, against medium-altitude long-endurance drones like the MQ-9 Reaper, the 358 missile has demonstrated a very high cost-effectiveness ratio—using tens of thousands of dollars in munitions to shoot down unmanned platforms worth tens of millions of dollars.

Zhang Xuefeng stated on the CCTV program that the 358 missile has no problem dealing with turboprop-powered MALE drones, with its core advantage being its extremely low cost. This analysis has been widely interpreted as the Chinese military closely monitoring how low-cost precision strike weapons could reshape the future battlefield landscape. In fact, China's own drone industry is already among the largest in the world, exporting various models from the Wing Loong series to the Rainbow series to multiple countries in the Middle East, and in the field of cruise missiles, China also has several product lines similar to the 358. The real combat data from the Middle Eastern battlefield is providing valuable references for Chinese military industry: how to build an interception and kill chain against enemy high-end unmanned systems while keeping costs under control.

From a broader strategic perspective, the exposure of the PLA's mine-laying drone tactics and the military's attention to the Iranian 358 missile point to a common trend: the People's Liberation Army is shifting from pursuing technological advantages of single platforms to constructing an asymmetric combat system characterized by low cost, high quantity, and intelligence. In the blockade concept of the first island chain, the AJX002 mine-laying drone, along with land-based anti-ship ballistic missiles, air power, and submarines, forms a multi-layered anti-access/area denial network, while the practical verification of the low-cost interception missile 358 provides a reference model for this network's anti-drone capabilities.

The defense preparedness situation on the Taiwan side is also worth noting. Recently, Taiwanese security scholars issued a warning, pointing out that Taiwan's civil defense system has serious resilience gaps, and that in the event of a real crisis, society may fall into panic due to inadequate preparation. This assessment indirectly confirms the potential deterrent effect of the PLA's blockade tactics—if the blockade itself can cause significant psychological impact and social turmoil within Taiwan Island, then the threshold for military action will be greatly lowered.

At the same time, the indirect impact of the situation in the Middle East on China's military strategy is also deepening. The Pentagon stated this week that China has committed not to provide weapons to Tehran during the ceasefire period. This diplomatic statement reflects the U.S. deep concern over China's role in the global military supply chain. Reports indicate that South Korea's THAAD-II air defense missile has achieved a 96.7% interception rate against Iranian drones and ballistic missiles, a statistic that may prompt Middle Eastern countries to increasingly turn to South Korea for military purchases, challenging China's dominant position in the Middle Eastern arms trade market.

In summary, several threads in the Chinese military field this week—the PLA's unmanned mine-laying tactics, research on low-cost precision strike weapons, optimization of the Taiwan Strait blockade strategy, and changes in the Middle Eastern arms trade landscape—together paint a picture of the PLA's ongoing deepening of asymmetric combat capability construction. While high-end platforms like the J-20 continue to be deployed, the emphasis on low-cost intelligent weapon systems is significantly increasing, a trend that deserves continued monitoring.
