What Taiwan’s Final Anping-Class Patrol Ship Reveals About Coast Guard Modernization

While the ships operate primarily as law‑enforcement patrol vessels, their design reveals a deeper strategic purpose: they are adapted from a naval missile corvette and can be armed during wartime if required.

A coast guard ship with naval DNA

The Anping class is derived from Taiwan’s Tuo Chiang‑class corvette, a stealthy fast‑attack catamaran developed for the Republic of China Navy. These naval vessels were designed to counter larger adversary ships through high speed, maneuverability, and reduced radar signatures.

Adapting this hull for coast guard use created a patrol vessel with unusual performance characteristics for a law‑enforcement fleet. The ships retain the catamaran hull and stealth‑influenced design features of the naval platform while replacing heavier combat systems with equipment suited for patrol and rescue missions.

Crucially, the design is “fitted for but not with” anti‑ship missiles, meaning weapons such as Taiwan’s Hsiung Feng series could be installed if the ships were mobilized in wartime.

The 12‑vessel production timeline

The Anping‑class ships were built by Jong Shyn Shipbuilding as part of Taiwan’s broader coast guard fleet renewal.

Key milestones include:

• 2018–2027 modernization plan: Taiwan committed about NT$42.6 billion (US$1.3 billion) to build 141 coast guard vessels across six types.
• 12 ships planned: The Anping class forms the 600‑ton offshore patrol segment of the program.
• Early deliveries: Production accelerated through the early 2020s as Taiwan prioritized domestic shipbuilding.
• February 2026: The 11th ship, Lanyu (CG‑613), was delivered to the Coast Guard Administration.
• May 15, 2026: Donggang (CG‑615) was launched as the 12th and final ship in the class.

Public reporting describes the May 2026 event as a launch and christening ceremony, rather than confirmation of final operational commissioning.

Key capabilities of the Anping class

The class combines patrol functionality with naval‑style performance features rarely seen in coast guard vessels.

Wave‑piercing catamaran hull
The twin‑hull configuration improves stability and allows high speeds while maintaining operational efficiency in rough waters.

High speed
The ships can reach over 40 knots, reflecting their origins in fast attack naval designs.

Extended patrol range
With a range of roughly 2,000 nautical miles, the vessels can patrol widely across Taiwan’s surrounding waters and offshore territories.

Waterjet propulsion
The vessels use waterjet propulsion systems, which provide rapid acceleration, shallow‑water maneuverability, and high‑speed efficiency.

Mission equipment
Standard equipment includes guns, remote‑controlled weapon stations, and systems for rescue, anti‑smuggling, and maritime enforcement missions.

Potential missile capability
In wartime scenarios, the ships can be equipped with Hsiung Feng II or III anti‑ship missiles, effectively transforming them into fast attack craft supporting naval operations.

Designed for gray‑zone maritime pressure

The modernization of Taiwan’s coast guard is closely tied to rising gray‑zone maritime pressure, including incursions by foreign coast guard vessels, illegal fishing activity, and damage to underwater infrastructure such as communications cables.

Fast, long‑range patrol vessels allow the CGA to respond quickly to incidents around Taiwan’s main island and its offshore territories while maintaining a persistent maritime presence.

At the same time, the dual‑use design ensures the ships could augment naval forces in a crisis, reinforcing Taiwan’s broader strategy of distributed and flexible maritime defense assets.

Why Donggang matters

The launch of Donggang represents more than the completion of a ship class. It demonstrates how Taiwan is reshaping its maritime security architecture:

• A modernized coast guard fleet with faster and more capable patrol ships
• Expanded domestic shipbuilding capacity supporting indigenous defense industries
• Dual‑use maritime assets that can shift from law enforcement to national defense in a crisis

In practical terms, the Anping‑class fleet strengthens Taiwan’s ability to manage daily maritime security challenges while quietly reinforcing its deterrence posture in the Taiwan Strait.
