Taiwan’s navy plans to use civilian fishing boats and chartered aircraft to map the beaches where China would most likely try to land in an invasion. According to the Taipei Times, which reported the plan on October 18, 2026, a senior military official described it as a first-of-its-kind initiative of the Ministry of National Defense’s Defense Innovation Division. The surveys will cover Taiwan’s “red beaches,” the sites judged most suitable for People’s Liberation Army (PLA) amphibious assaults.
Estimates by the ministry, US think tanks and Taiwan’s Institute for National Defense and Security Research put the number of likely landing sites at between four and 20. They include Zhuwei in Taoyuan, Wazihwei in New Taipei City’s Bali District and Sishu in Tainan. The list has since been widened to include “composite red beaches,” which combine port facilities with terrain suitable for airborne operations (Taipei Times).
The problem is that the coastline keeps changing. Until now, the navy’s 192nd and 151st fleets collected hydrographic data during their training exercises. But seasonal shifts and typhoons constantly reshape the near-shore seabed, and the navy’s survey ships have proven too slow and inflexible to keep up. Under the new plan, the military will hire private survey companies. Fishing boats fitted with multibeam echo sounders will map water as shallow as 3 meters, where large ships cannot go. Chartered aircraft will use airborne laser scanning (LiDAR) that sees through the water’s surface to build 3D models of the terrain above and below the waterline. The official said this will let the military collect coastal data dozens of times faster than before (Taipei Times).
The purpose is to deny the PLA a landing. The data will show deep channels where mines can be laid and reefs where obstacles can be placed to block landing routes for ships, amphibious vehicles and hovercraft. To limit the security risk, the civilian contractors will collect only raw physical data, which the official compared to “meaningless fragments of a code.” Processing, and the step of linking the data to counter-landing plans, will stay inside military units such as the Naval Meteorological and Oceanographic Office (Taipei Times).
The significance is twofold. First, Taiwan is treating knowledge of its own coastline as a combat capability that must be refreshed constantly, rather than a static chart. A mine barrier built on last season’s seabed may not stop next season’s landing craft. Second, the plan treats civilian boats, aircraft and commercial technology as part of the defense effort, an approach the official tied directly to the model of the US Defense Innovation Unit.
The open question is how well the security arrangements hold up. Contractors, crews and data handlers all become possible points of exposure in a society that Beijing is working hard to penetrate. Splitting raw data collection from military analysis helps, but its value depends on how strictly that division is enforced.
