Modernization of the PLA Under Dual Pressure: The Strategic Logic of the 055 Destroyer's First Live-Fire Exercise in the Eastern Theater and the J-6's Unmanned Transformation

In late March 2026, the People's Liberation Army (PLA) released two military signals in the Taiwan Strait that warrant deep attention: the Eastern Theater Command Navy's newly commissioned two Type 055 destroyers completed their first live-fire training, and a formal assessment report revealed that the PLA plans to convert over 200 aging J-6 fighter jets into unmanned attack platforms and forward deploy them near the Taiwan Strait. Although these two events appear independent, they are strategically unified, pointing to the PLA's comprehensive acceleration in building system combat capabilities.

The deployment of Type 055 destroyers in the Eastern Theater Command has significant directional implications. According to a report by the PLA Daily on March 23, the ships participating in the live-fire training were the Dongguan (hull number 109) and the Anqing (hull number 110) — the first batch of Type 055 destroyers under the Eastern Theater Command Navy. Both ships belong to the second batch of construction and have improvements in sensor integration and electronic warfare systems compared to the first batch of Type 055s. The training subjects included high-speed aerial target interception in strong electromagnetic interference environments and multi-wave saturation strikes against enemy surface vessels using island reefs for cover. From the setup of the training subjects, it is evident that this is tailored for the complex battlefield environment of the Taiwan Strait, rather than a routine exercise.

The Type 055 destroyer has a full-load displacement of about 12,000 tons and is equipped with a 112-cell vertical launch system, capable of integrating various munitions such as the HQ-9B long-range surface-to-air missile, YJ-18 anti-ship missile, and anti-submarine missiles. It is currently one of the most capable surface combatants in the Asia-Pacific region. Concentrating such platforms in the Eastern Theater Command, responsible for the Taiwan Strait and East China Sea, indicates that the PLA is consciously strengthening high-end maritime combat capabilities in this direction, rather than dispersing top-tier equipment in regions with relatively lower geopolitical pressure. A senior officer from the Eastern Theater Command Navy explicitly stated in official reports that the two ships will accelerate their integration into the joint combat system — this statement conveys information that goes beyond just technical aspects.

At the same time, the Mitchell Institute for Aerospace Studies released another important clue in its "China Air Power Tracker" report in February 2026: the PLA has converted over 200 J-6 aircraft into unmanned attack platforms (designated as J-6W), which are dispersed across five forward airbases in Fujian Province and one airbase in Guangdong Province, including the Longtian Air Force Base, which is close to the median line of the Taiwan Strait. Commercial satellite images show that these swept-wing aircraft are arranged in a ready-to-use posture on the tarmac and alongside runways.

The unmanned modification of the J-6 is quite pragmatic. This aircraft was originally a domestically produced model that replicated the Soviet MiG-19 in the 1960s and has long been retired from frontline manned combat units. During the modification process, the PLA integrated an automatic flight control system and terrain-matching navigation technology into the airframe, and in some variants, removed the cannon to install additional electronic equipment. J. Michael Dahm, a senior researcher at the Mitchell Institute and former U.S. Navy intelligence officer, estimates that the total number of modified J-6s may exceed 500, with the current forward deployment representing only a portion of the available inventory.

The strategic intent behind this plan is to consume the opponent's air defense resources at a low cost. In the initial phase of a conflict in the Taiwan Strait, a large number of J-6W drones could serve as the first wave of saturation attack platforms to forcibly open an air defense corridor, consuming the stockpiles of Standard-2, Patriot, and Sky Bow air defense missiles deployed by Taiwan and the U.S. in that direction, thereby creating favorable conditions for subsequent manned fighter jets and precision-guided munitions to penetrate defenses. The cost of a modern air defense missile is often several times or even dozens of times that of a modified J-6, and this asymmetric cost logic has significant advantages in a war of attrition.

When examining the above two dynamics within a broader policy framework, it becomes clear that there is a well-defined top-level design behind them. The 14th National People's Congress held its fourth session from March 5 to 12, 2026, officially approving the "Outline of the 15th Five-Year Plan for National Economic and Social Development." In terms of military modernization, the 15th Five-Year Plan explicitly emphasizes advancing the PLA's transformation towards intelligent warfare, focusing on key areas such as artificial intelligence, unmanned and autonomous systems, networked information infrastructure, and the application of emerging technologies. The 2026 defense budget increased by 7% year-on-year, reaching approximately 1.91 trillion yuan (about $277 billion), providing solid financial support for the aforementioned projects.

The unmanned modification of the J-6 and the forward deployment of Type 055 destroyers are typical cases of the concept of intelligent warfare transitioning from strategic text to actual combat capability. The former represents compensating for technological gaps with numerical advantages and cost asymmetry, while the latter represents strengthening high-end combat capabilities in key strategic directions with top-tier platforms — both are complementary and together form the PLA's dual-track approach to addressing future high-intensity conflicts.

In summary, the two developments in late March 2026 indicate that the PLA's preparations in the Taiwan Strait are systematically accelerating. Particularly noteworthy is the timing: Japanese Prime Minister Sanae Takaichi publicly stated in November 2025 that Japan might militarily intervene if a conflict occurs in the Taiwan Strait, leading to continued pressure on China-Japan relations; meanwhile, the U.S. defense budget negotiations and Indo-Pacific strategy adjustments are also at a critical window. In this external environment, the PLA's choice to showcase two distinctly different but complementary combat capabilities at this time is no coincidence. For regional security assessors, this is not just about weapon dynamics, but also an important reference regarding the PLA's strategic intentions and timeline.
