The Taiwanese navy has launched sea trials for the ROCS Chengde (1208), its first Kang Ding-class frigate to undergo a full modernization program. This step represents a major advance in Taiwan’s naval capabilities amid growing regional tensions.
The frigate’s trial, carried out from the port of Kaohsiung, follows the integration of the Type 997 surveillance radar and the Huayang vertical launch system (VLS). As reported by Zona Militar, this upgrade is aimed at narrowing the technological gap with the People’s Liberation Army and significantly improving air defense.
Taiwan’s modernization of its surface fleet reflects a broader plan to reinforce maritime security. By replacing outdated equipment with advanced systems, the navy seeks to enhance its defensive posture while ensuring that its ships remain effective against evolving threats.

Significant Sensor and Missile System Upgrades
The ROCS Chengde began its modernization in late 2023. The Type 997 radar was installed in April 2025, followed by the Huayang VLS in June. The new system, integrated directly into the hull, allows the frigate to carry up to 32 Sea Sword II (Hai Chien II) surface-to-air missiles, replacing the obsolete Sea Chaparral launcher that was limited to four missiles with an 8 km range.
The Type 997 radar, which is already operational aboard several Royal Navy ships, brings expanded detection capabilities and faster target tracking. Its addition represents a substantial improvement in the vessel’s ability to operate effectively in multi-threat environments.
Modernization Timeline and Planned Upgrades for the Fleet
The modernization of the ROCS Chengde is expected to conclude by September 2025, after which the frigate will return to active service. Starting in 2026, the navy intends to modernize the remaining five Kang Ding-class ships at a rate of one per year.
This program also includes the replacement of the DRBV-26D “Jupiter II” radars with the more advanced ARTISAN 3D radar (Type 997). Capable of operating at double the rotation speed of its predecessor, the new radar will bring a standardized level of performance across the fleet.
Financial Investment and International Cooperation
This effort is backed by a multi-year investment of NT$43.1 billion (approximately USD 1.37 billion). In addition, Taiwan signed a spare parts supply agreement worth NT$2.49 billion (USD 79.37 million) with France in 2024. This deal, running until January 2026, secures the logistical support necessary to maintain the Kang Ding-class frigates in operational condition.
These agreements underscore the longstanding defense cooperation between Taiwan and France, dating back to Taiwan’s purchase of six La Fayette-class frigates in 1991. The modernization program now underway addresses the limitations these ships have faced for decades, particularly in air defense.
