2026 Taipei Security Dialogue Focuses on 145-Kilometer Strait, PLA 054A Frigate System Faces New Arithmetic

The 2026 Taipei Security Dialogue held on September 10 sent a signal that is more worthy of contemplation than mere slogans. Raymond Greene, director of the American Institute in Taiwan, did not focus on "defeating" the aggressor but emphasized that Taiwan must make potential adversaries believe that deploying and sustaining large ground forces on the island is extremely difficult. This judgment brings the issue back to the 145-kilometer strait, urban terrain, and sustained supply, rather than a competition of weapon ranges.

The South China Morning Post reported on September 12 about this statement and the criticisms from mainland China. For the PLA, the real pressure lies in the fact that an amphibious operation must first establish a stable maritime corridor. Therefore, while frigates may seem less eye-catching than aircraft carriers and large destroyers, they could be the foundation for sustained operations.

The Value of 054A Is Not in "Single Ship Victory"

On September 2, U.S. Defense News analyzed that the 054A frigate has capabilities for both near-sea and far-sea missions, capable of performing anti-submarine, escort, and fleet air defense tasks; public information generally indicates that the ship has a full-load displacement of about 4,000 tons, equipped with a 32-cell vertical launch system, and carries onboard helicopters. It is important to emphasize that these parameters do not mean that the 054A can independently suppress the Taiwanese or U.S. Navy. Its significance lies in its quantity, maintainability, and mission coverage.

A single 054A has limited missile carrying capacity, and its radar and area air defense capabilities cannot be compared to those of the 055 destroyer. However, in the Eastern Theater Command fleet, it can partially free up more expensive large vessels from anti-submarine, surveillance, and short-range escort tasks. In simple terms, the 055 destroyer is the "high-end node" of the fleet, while the 054A is more like a "workhorse" that continuously fills in. Only through the cooperation of both can a one-time exercise-style assault be transformed into multi-day or even longer maritime operations.

Taiwan's Unmanned Approach Will Change Escort Costs

Greene mentioned unmanned systems, mission command, and social resilience during the dialogue, emphasizing that the core is not to manufacture a batch of expensive platforms, but to continuously deplete the PLA's reconnaissance, mine-sweeping, anti-submarine, and air defense resources before they approach the coast. For the landing fleet, the most dangerous threat may not be a high-intensity volley, but rather low-cost drones, unmanned boats, and distributed sensors that constantly force escort ships to power up, change course, and resupply ammunition.

This will shift the PLA's military industrial challenge from "Can we build advanced vessels?" to "Can we maintain a maritime barrier at an acceptable cost?" The advantage of the 054A is its maturity and scale, while its shortcoming lies in ammunition consumption and short-range defense pressure when facing dense unmanned swarms. If every low-cost target requires expensive air defense missiles for interception, the economic viability of the escort system will quickly deteriorate.

The Japanese Factor Extends the Issue to the First Island Chain

The military section of the South China Morning Post recently pointed out that Japan is advancing its military transformation aimed at China, but is simultaneously constrained by budget, personnel, and political factors. For the PLA, Japan's anti-submarine aircraft, submarines, and bases in the southwestern islands mean that operations in the Taiwan Strait cannot only calculate threats within the strait but must also include reconnaissance from the Miyako Strait, East China Sea routes, and the outer side of the first island chain in the same table.

Therefore, the value of training and deploying the 054A is not only to increase the number of vessels but also to help the Eastern Theater Command maintain multi-axis maritime presence. Whether it can maintain fleet coordination under high-intensity electromagnetic interference, unmanned platform harassment, and long-range fire threats remains insufficiently documented. The author believes that what is truly worth observing next is not how many missiles the 054A can carry, but whether the PLA can establish cheaper counter-unmanned systems, resupply nodes, and battle damage replacement mechanisms—this will ultimately determine whether the 145-kilometer strait is merely a surface obstacle or a prolonged war of attrition.
