Корвети класу Tuo Chiang

The Tuo Chiang-class corvette is a Taiwanese-designed class of fast (up to 45 knots, 83 km/h, 52 mph) and stealthy multi-mission corvettes built for the Republic of China (Taiwan) Navy. It is designed to counter the numerous and increasingly sophisticated People's Liberation Army Navy ships by utilizing hit-and-run tactics, and thus featured clean upper structure design with very few extrusions to reduce radar signature, pre-cooled engine exhaust to reduce infrared signature, and a reduced visual signature to reduce chance of detection.

The program was announced by the Republic of China (Taiwan) Ministry of National Defense (MND) on 12 April 2010. It was developed by the Naval Shipbuilding Center in Kaohsiung, The Tuo Chiang class was developed to address common weakness of traditional small warships such as patrol craft and corvettes namely poor sea-keeping, a significant handicap for warships expected to sortie for extended periods of time in rough seas around Taiwan.

In 2011, the Taiwanese Legislative Yuan approved a NT$24.98 billion (US$853.4 million) budget to fund the construction of up to 12 ships. The prototype of the Hsun Hai program was named and christened on Friday, 14 March 2014 as ROCS Tuo Chiang (PGG-618) in honor of the gunboat that was a combatant in the 9-2 Sea Battle during Second Taiwan Strait Crisis.

In 2019 work commenced on the first of twelve 600-ton coastal patrol vessels for the Coast Guard Administration, the Anping-class offshore patrol vessel, based on the Tuo Chiang-class corvette at the Jong Shyn Shipbuilding Company's Kaohsiung shipyard.

The ship is a catamaran design which is 60.4 metres (198 ft) long, 14 metres (46 ft) wide and carries a crew of 41 personnel. It is capable of a maximum speed of 40 knots and a range of 2,000 nautical miles (3,700 km; 2,300 mi). It is armed with eight subsonic Hsiung Feng II and eight supersonic Hsiung Feng III anti-ship missiles launchers, a Phalanx Close-In Weapons System, and a 76 mm (3 in) main gun. The ship can operate up to sea state 7 in waves up to 6.1-9.1 m high. Taiwan Security Analysis Center (TAISAC) stated that the ship features stealth technologies to help evade radar detection, a combat system that includes a distributed-architecture combat direction system known as “Taiwan Aegis" developed by the National Chung-Shan Institute of Science and Technology and an indigenous search/track and fire-control radar and electro-optical director.
