Lungteh Shipbuilding

Lungteh Shipbuilding, also known as Lung Teh or Longde, is a Taiwanese ship and boat builder headquartered in Yilan County. Established in 1979, the company operates five production facilities in Yilan County and maintains offices in Taipei and Singapore. Its work spans commercial, government, defense, and specialized maritime applications, with products ranging from fast ferries and pilot boats to coastal patrol craft, fireboats, wind-farm support vessels, special-forces craft, minelayers, corvettes, and unmanned maritime vehicles. The company has become particularly visible through its role in Taiwan's naval shipbuilding program. In 2018, Lungteh won a contract to build eleven Tuo Chiang Block II corvettes and four minelayers for the Republic of China Navy. The Tuo Chiang program is associated with Taiwan's asymmetric naval-defense strategy because the vessels combine speed, relatively small size, and anti-ship capabilities intended to complicate operations by a larger adversary. In May 2019, President Tsai Ing-wen visited Lungteh to highlight the corvette program and Taiwan's emphasis on domestic defense production, technological innovation, and asymmetric military procurement. Lungteh also expanded its profile in research and unmanned maritime technology. In 2019, it launched Glorious Star, an 80-ton, 28-meter high-speed catamaran research and test vessel developed for Taiwan's National Chung-Shan Institute of Science and Technology. The company has worked with Singapore's ST Engineering on the Venus 16 unmanned surface vehicle and with NCSIST on the Hui Long-class unmanned underwater vehicle. In 2025, Lungteh's Black Tide unmanned surface vessel entered trials conducted by the Taiwanese military. The craft was described as capable of reaching 43 knots and configurable for reconnaissance or strike missions. The company's naval production has included both corvettes and minelayers. Lungteh launched the first Min Jiang-class minelayer in August 2020, and delivery of the initial four-vessel order was completed in December 2021. In March 2024, the final two vessels of an initial six-ship corvette order, An Chiang and Wan Chiang, were commissioned at Su'ao Harbor in Yilan. Production of a second corvette batch began in 2024, with five ships planned and completion expected by the end of 2026; the first second-batch vessel, Dan Chiang, was launched in July 2025. In April 2025, the Taiwanese Navy placed an order for six additional Min Jiang-class minelayers. Lungteh has also pursued international defense cooperation. It participated in the IDEX defense exhibition in 2019 alongside other Taiwanese defense companies and has partnered in producing the Multipurpose Assault Craft family for the Philippine Navy. The company therefore occupies a position at the intersection of commercial shipbuilding, specialized vessel construction, indigenous Taiwanese defense procurement, and emerging unmanned maritime systems. In July 2025, China placed Lungteh on an export-control list because of its work for Taiwan's military. Lungteh responded that the materials it sourced from China were highly replaceable, underscoring the supply-chain and geopolitical pressures surrounding its defense business.

Lungteh Shipbuilding was established in Taiwan in 1979 and developed as a builder of specialized ships and boats. Based in Yilan County, the company established a production footprint consisting of five facilities in the county, supplemented by offices in Taipei and Singapore. Its output has included fast ferries, wind-farm supply vessels, coastal patrol craft, high-speed craft for special forces, fireboats, pilot boats, and other vessels requiring speed, maneuverability, or mission-specific equipment. A major change in Lungteh's public profile came with its growing involvement in Taiwan's indigenous naval shipbuilding effort. In 2018, it won a contract to produce eleven Tuo Chiang Block II corvettes and four minelayers for the Taiwanese Navy. The Tuo Chiang program became closely associated with Taiwan's asymmetric defense concept, in which relatively compact and fast platforms are used to provide sophisticated capabilities without relying exclusively on large surface combatants. During a May 2019 visit to Lungteh, President Tsai Ing-wen used the corvette program to promote domestic defense manufacturing and argued for military procurement centered on technology and asymmetric capabilities. Lungteh continued to broaden its technical portfolio beyond conventional shipbuilding. In 2019, it launched Glorious Star, an 80-ton, 28-meter high-speed catamaran designed as a research and test vessel for the National Chung-Shan Institute of Science and Technology. The company also participated in international defense marketing, exhibiting at IDEX in 2019 alongside other Taiwanese defense companies. Its collaborative work included the Venus 16 unmanned surface vehicle with ST Engineering and the Hui Long-class unmanned underwater vehicle with NCSIST. The minelayer program became one of Lungteh's principal naval production activities. The first of four Min Jiang-class minelayers ordered by Taiwan's Navy was launched in August 2020, and delivery of the initial class order was completed in December 2021. The company later received an order for six additional Min Jiang-class vessels in April 2025, extending its role in Taiwan's naval mine-laying capability. The first corvette order progressed through commissioning and follow-on production. In March 2024, the final two ships of the initial six-vessel corvette batch, An Chiang and Wan Chiang, were commissioned at Su'ao Harbor in Yilan. A second batch of five corvettes entered production in 2024, with completion expected by the end of 2026. Dan Chiang, identified as PGG-627, was launched in July 2025 as the first ship of that batch. Lungteh has also participated in overseas defense-industrial cooperation. It is a partner in production of the Multipurpose Assault Craft family for the Philippine Navy, which had four variants reported by 2018. This work complements the company's commercial and Taiwanese government projects and illustrates its strategy of applying high-speed vessel expertise across multiple maritime missions. In 2025, Lungteh's Black Tide unmanned surface vessel entered trials conducted by the Taiwanese military. The vessel was described as capable of a top speed of 43 knots and configurable for reconnaissance or strike operations. The same year brought a geopolitical supply-chain challenge: China placed Lungteh on an export-control list because of its work for Taiwan's military. Lungteh responded that the materials it obtained from China were highly replaceable. The episode highlighted the strategic sensitivity of the company's defense activities and the importance of resilient sourcing for Taiwan's shipbuilding sector.
