The Tuo Chiang-class corvette ({{zh|t=沱江|l=Tuo River}}) is a Taiwanese-designed class of fast (up to {{convert|45|kn|lk=in|disp=comma}}) 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 features 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.{{Cite web|url=https://www.foxnews.com/tech/taiwanese-navy-showcases-new-killer-stealth-warship|title=Taiwanese Navy showcases new 'killer' stealth warship|date=24 March 2015|website=Fox News}}{{Cite web|url=https://www.defensenews.com/naval/2014/12/23/taiwan-launches-its-largest-ever-missile-ship/|title=Taiwan Launches Its Largest-Ever Missile Ship|agency=Agence France-Presse|date=8 August 2017|website=Defense News}}{{Cite web|url=https://phys.org/news/2011-07-taiwan-stealth-technology-breakthrough.html|title=Taiwan in stealth technology breakthrough: report|website=phys.org}}{{Cite web|url=https://www.popsci.com/article/technology/taiwan-navy-launches-new-stealth-boat/|title=Taiwan Navy Launches New Stealth Boat|date=18 March 2019}}{{Cite web|url=https://www.businessinsider.com/taiwan-navy-stealth-missile-warship-corvette-2014-12|title=The Taiwan Navy Just Unveiled A Stealth Missile Warship Dubbed The 'Carrier-Killer'|author=Devan Joseph|agency=Associated Press|website=Business Insider}}{{Cite web|url=https://news.usni.org/2014/12/24/taiwan-navy-takes-delivery-first-stealth-carrier-killer-corvette|title=Taiwan Navy Takes Delivery of First Stealth 'Carrier Killer' Corvette|date=24 December 2014}}{{Cite web|url=https://www.scmp.com/news/china/article/1668158/taiwan-navy-testing-stealth-frigates|title='Stealth' frigate handed over to Taiwan's Navy|date=23 December 2014|website=South China Morning Post}}

Development

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,{{cite web|url=http://www.taipeitimes.com/News/taiwan/archives/2012/04/28/2003531472|title='Carrier killer' program goes ahead|last=Cole|first=J. Michael|date=12 April 2012|work=Taipei Times |access-date=22 August 2015 |location=Taipei}} The Tuo Chiang class was developed to address common weakness of traditional small warships such as patrol craft and corvettes not fit for extended periods of time in rough seas around Taiwan Island.

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.{{cite web|url=http://www.wantchinatimes.com/news-subclass-cnt.aspx?cid=1101&MainCatID=11&id=20140314000089|title=Taiwan's first stealth missile corvette christened Tuo River|date=14 March 2014|work=Want China Times|access-date=22 August 2015|archivedate=29 October 2014|archiveurl=https://web.archive.org/web/20141029141435/http://www.wantchinatimes.com/news-subclass-cnt.aspx?cid=1101&MainCatID=11&id=20140314000089|url-status=deviated}} On 18 April 2011 a top military officer and a lawmaker announced that the construction of a 500-ton prototype would begin in 2012. 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.{{Cite web |url=http://udn.com/NEWS/BREAKINGNEWS/BREAKINGNEWS1/8546874.shtml |title=海軍沱江軍艦擲瓶下水 | 要聞 | 即時新聞 | 聯合新聞網 |access-date=14 March 2014 |archive-url=https://web.archive.org/web/20140314150637/http://udn.com/NEWS/BREAKINGNEWS/BREAKINGNEWS1/8546874.shtml |archive-date=14 March 2014 |url-status=dead |df=dmy-all }}

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 mass production cost of the Tuojiang ship is 3.2 billion higher than that of the first prototype ship already in service, after deducting the hull. 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. The anti-aircraft missile is the standard configuration of the ship.

In early 2016, the ROC Navy began plans for procuring three air defense frigates. It has been speculated that these frigates would possibly be catamarans based on the Tuo River-class hull. Expected weapon systems include the Mark 41 Vertical Launching System (VLS) equipped with a naval variant of the Sky Bow III and the Sky Sword II, as well as the Sea Oryx CIWS system.[http://www.navyrecognition.com/index.php?option=com_content&task=view&id=3699 ROC Navy to Build Three Air Defense Catamaran Corvettes based on Tuo River-class] {{Webarchive|url=https://web.archive.org/web/20160530031207/http://www.navyrecognition.com/index.php?option=com_content&task=view&id=3699 |date=30 May 2016 }} – Navyrecognition.com, 15 March 2016 It will field a ballistic missile defense version of the Sky Bow III missile defense system to shoot down incoming enemy ballistic missiles.[http://navyrecognition.com/index.php/news/defence-news/2017/january-2017-navy-naval-forces-defense-industry-technology-maritime-security-global-news/4750-taiwan-s-ncsist-successfully-tested-a-ship-based-variant-of-tien-kung-iii-bmd-interceptor.html Taiwan's NCSIST Successfully Tested a Ship-based Variant of Tien Kung III BMD Interceptor] – Navyrecognition.com, 2 January 2017

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.{{cite web |last1=hen Chi-feng and |first1=William Yen |title=Construction works for 600+ tonne CGA ship starts in Kaohsiung |url=http://focustaiwan.tw/news/aeco/201901040024.aspx |website=focustaiwan.tw |date=4 January 2019 |publisher=Focus Taiwan |access-date=23 May 2019}}

Design

The ship is a wave-piercing catamaran design which is {{convert|60.4|m|ft}} long, {{convert|14|m|ft}} wide and carries a crew of 41. It is capable of a top speed of 40 knots and a range of {{convert|2000|nmi|lk=in}}. 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 {{convert|76|mm|in|abbr=on|0}} main gun. The ship can operate up to sea state 7 in waves up to {{convert|20|-|30|ft|m|abbr=on}} high. 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{{cite web |last1=Minnick |first1=Wendell |title=Taiwan Moves on $14.7B Indigenous Shipbuilding, Upgrade Projects |url=https://www.defensenews.com/naval/2016/06/23/taiwan-moves-on-14-7b-indigenous-shipbuilding-upgrade-projects/ |website=defensenews.com |date=23 June 2016 |publisher=Defense News |access-date=16 July 2019}} and an indigenous search/track and fire-control radar and electro-optical director.{{cite web |url=http://www.upi.com/Business_News/Security-Industry/2010/04/13/Taiwan-shows-images-of-carrier-killer/UPI-94971271173599/ |title=Taiwan shows images of carrier killer |website=UPI.com |date=13 April 2010 |access-date=22 August 2015}}{{cite web |url=http://www.spacewar.com/reports/Taiwan_developing_carrier_killer_for_navy_report_999.html |title=Taiwan developing 'carrier killer' for navy: report |website=Spacewar.com |date=12 April 2010 |access-date=22 August 2015}}{{cite web |url=http://www.defensenews.com/story.php?i=4588116 |archive-url=https://archive.today/20120730105135/http://www.defensenews.com/story.php?i=4588116 |url-status=dead |archive-date=30 July 2012 |title=Taiwan Plans Stealthy 900-Ton Warships |website=Defensenews.com |last=Minnick |first=Wendell |date=18 April 2010 |access-date=22 April 2015 }}{{cite web |url=https://www.tadte.com.tw/en_US/industry/news/info.html?id=EB027BC3EA278639 |archive-url=https://archive.today/20130920185231/https://www.tadte.com.tw/en_US/industry/news/info.html?id=EB027BC3EA278639 |url-status=dead |archive-date=20 September 2013 |title=Missile Launchers, Vessels, UAVs Unveiled at TADTE |website=Taipei Aerospace & Defense Technology Exhibition |date=17 August 2013 |access-date=22 August 2015 }}

The ship increases its survivability in naval warfare by utilizing advanced stealth technology and low radar cross section (RCS), which makes it less detectable by radar and allows it to be obscured by background radar noise when operating closer to the coastline.[https://news.usni.org/2016/03/25/taiwan-navy-emphasizing-domestic-shipbuilding-program-in-ongoing-maritime-restructure Taiwan Navy Emphasizing Domestic Shipbuilding Program in Ongoing Maritime Restructure] – News.USNI.org, 25 March 2016
