'Tuo River') 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.

In the Taipei Aerospace and Defense Technology Exhibition in 2013, the Navy unveiled a model of the Hsun Hai project corvette.

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 in the September 2 Sea Battle during the Second Taiwan Strait Crisis.

[14] The Ministry of National Defense prepared a budget of more than NT$16.395 billion in order to secure the follow-up mass production of three Tuojiang ships from 2017 to 2025.

The Navy said that the prototype ship did not take into account the cost of missiles, and the mass-produced type was mainly used for combat readiness.

[4] Taiwan Security Analysis Center (TAISAC) stated that the ship features stealth technologies to minimize 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[19] and an indigenous search/track and fire-control radar and electro-optical director.
