Taiwan's Harpoon Coastal Defense System Hits
A US Navy developmental test of the land-based Harpoon Coastal Defense System (HCDS) resulted in a direct hit on a target vessel.
The US Navy has conducted a successful live-fire test of the Harpoon Coastal Defense System (HCDS) destined for Taiwan. The land-based missile system scored a direct hit on a target vessel during the developmental trial, a critical step in fulfilling Taipei's $2.3 billion order.
According to a release from the Portfolio Acquisition Executive Munitions, the test validated the system's ability to engage at-sea threats from land. "During the event, the Harpoon missile successfully launched from land and engaged the target vessel in near-shore/littoral waters," the statement read. A Naval Air Systems Command official called the event a significant milestone in delivering a high-priority defense capability.
System Details and Delivery
The HCDS is a Boeing-made system designed to provide a robust, land-based anti-ship capability. It leverages the proven Harpoon missile to protect coastal assets and waterways. Further trials are planned for the second phase of the developmental program.
Taiwan procured the system in a 2023 deal worth up to $2.3 billion. The contract, reported by Taiwan News as being inked by NAVAIR on Taipei's behalf, includes 100 launchers and 400 RGM-84L-4 Harpoon Block II missiles. This purchase supplements Taiwan's existing stocks of ship-launched and air-launched Harpoons. At least five HCDS launchers and a radar vehicle have already been delivered.
A Taiwanese defense observer stated the system is mounted on a Heavy Expanded Mobility Tactical Truck (HEMTT), differing from Boeing's earlier trailer-based designs for other countries. Test media showed a gray HEMTT with a command cabin and four missile canisters.
Taiwan's Integrated Coastal Defense
Taiwan's new HCDS units will operate alongside domestically-built anti-ship missile systems. These include the subsonic HF-2 and the supersonic HF-3. Taiwanese forces have been reinforcing stockpiles of these missiles since the early 2020s under the "Sea-Air Combat Power Improvement Plan," adding hundreds between 2022 and 2026. Further developments have reportedly expanded their ranges out to 1,500 kilometers.
Taipei's strategy involves deploying Harpoons, its own missiles, and one-way attack drones to counter a potential invasion. Investments in these weapons are viewed as crucial for a high-intensity Taiwan Contingency Operation. Reuters estimates that the island's forces will possess at least 1,800 anti-ship missiles by 2029.
