Taiwan's Ocean Affairs Council is developing an autonomous system to let drone fleets coordinate and carry out maritime missions without human intervention, in response to "grey-zone" activities by China around the island, according to a report from Tom's Hardware citing the South China Morning Post.

Working with National Cheng Kung University, the council has already completed simultaneous flight simulations of two drone fleets of 10 aircraft each, moving from individual aircraft control to coordination between detachments. "The next stage will involve hardware-in-the-loop testing, prototype integration and flight trials over actual maritime areas to assess reliability under different sea and weather conditions," the council said.

The project is designed to help Taiwan's Coast Guard Administration counter Chinese grey-zone tactics in surrounding waters. The report notes instances of civilian Chinese ships damaging undersea cables that Taipei relies on, prompting the CGA to increase defensive patrols around 24 undersea cables and monitor nearly a hundred China-linked boats. It also says Chinese "research vessels" continue to loiter over Taiwan-U.S. undersea cables, mimicking the activities of Russian trawlers in the Atlantic.

The drones are programmed with a minimum separation of 100 feet in three-dimensional space, and the system incorporates leader-follower formation flying and dynamic obstacle avoidance. It is intended to let different types of drones coordinate movements, divide tasks and plan routes, mainly for maritime surveillance.

The project is focusing on three Western-made drones: the Jump 20, the V-BAT and the Flexrotor. The Ocean Affairs Council has just received the V-BAT, a vertical take-off and landing drone built by U.S. defense firm Shield AI. It can operate for more than 12 hours and can take off from constrained deck space, which the report says suits the Coast Guard Administration without major ship renovations.

Analysis

Why This Matters

  • The project aims to automate maritime surveillance over waters where reports say Chinese vessels have damaged undersea cables that Taiwan relies on, potentially changing how the island protects critical infrastructure.
  • It marks a shift from single-drone control to coordinated multi-fleet operations, which could extend the Coast Guard Administration's reach without major upgrades to its ships.
  • The development is part of a wider regional pattern in which autonomous systems are being used to respond to pressure campaigns that stop short of open conflict.

Background

Grey-zone tactics generally refer to coercive actions below the threshold of open armed conflict, often using civilian and paramilitary assets to test an opponent's limits. Taiwan's Coast Guard Administration is the main agency responsible for maritime law enforcement around the island, and the reported drone project is one response to Chinese vessels said to be damaging undersea cables and loitering over cable routes. The work is still at an early stage: simulations of two 10-drone fleets have been completed, and the next milestones are hardware-in-the-loop testing, prototype integration and flight trials over maritime areas.

What to Watch

  • Whether the council completes hardware-in-the-loop testing and begins flight trials over actual maritime areas, and how the drones perform in different sea and weather conditions.
  • How the Coast Guard Administration uses the V-BAT drones it has received, and whether the Jump 20 and Flexrotor follow.
  • Any further incidents near undersea cables, which could accelerate the project or reshape its priorities.
