Taiwan has started receiving U.S.-made land-based Harpoon Coastal Defense Systems, part of a 100-system, 400-missile program, with phased deliveries continuing through 2028 to strengthen the island’s naval coastal defense and modernize its forces.
Taiwan has reportedly started receiving shipments of U.S.-made land-based Harpoon anti-ship missile systems, marking a significant step in the island’s efforts to strengthen its coastal defense capabilities. Local reports and photos have confirmed the arrival of associated convoy vehicles, including mobile missile launchers, radar units, and command-and-control vehicles. The launcher trucks are based on the Heavy Expanded Mobility Tactical Truck (HEMTT) platform, providing mobility and flexibility for coastal defense operations.
Under previously disclosed procurement plans, Taiwan ordered 100 land-based Harpoon Coastal Defense Systems along with a total of 400 missiles. The acquisition was approved through U.S. foreign military sales channels and is intended to bolster Taiwan’s ability to deter or counter surface threats approaching its coastline.
Deliveries are being executed in phases, as agreed between Taipei and Washington. According to the current schedule, 32 complete systems are expected to be delivered by the end of 2026, with the remaining 68 systems arriving by 2028. The phased approach starts with the shipment of training simulators and deployment of U.S. instructors and technical advisers, followed by the delivery of mobile launchers, radar systems, and support equipment. The missiles themselves are delivered in the final stage, allowing Taiwanese forces to complete training and integration before receiving live munitions.
The systems will be operated by Taiwan’s naval coastal defense command. The land-based Harpoon missiles supplied are the RGM-84L-4 Block II (U) variant, a modernized version of the Harpoon missile family. The Block II variant features enhanced guidance and targeting capabilities, optimized for complex littoral environments and capable of engaging moving surface targets.
There are differing assessments of the missile’s maximum range. According to Boeing, the manufacturer, the RGM-84L-4 exceeds 67 nautical miles (approximately 124 kilometers). Taiwanese Navy officials have stated that the variant they received offers improved performance compared to earlier U.S. military versions, while some external sources estimate the range could exceed 148 kilometers.
The Harpoon Coastal Defense System integrates mobile launchers, sensors, and command units into a road-mobile and dispersed architecture. This design allows missile units to relocate quickly and operate from concealed positions, enhancing survivability in a contested environment.
The arrival of these first system components comes as part of Taiwan’s ongoing defense modernization, driven by regional security pressures. The focus on mobile and survivable systems is intended to complicate potential amphibious or naval operations against the island and strengthen deterrence across its coastal waters.
