Yoon Youngha-class patrol vessel
ship class
The Yoon Youngha-class patrol vessel (Hangul: 윤영하급 미사일고속함) also known as PKG-class patrol vessel is a class of patrol ship of the Republic of Korea Navy named after Yoon Young-ha. One variant is in active service and a smaller variant is planned. The first being the PKX-A or Yun Youngha-class missile patrol ship (Hangul: 윤영하급 고속함), and the second the PKX-B patrol boat (also known as Chamsuri-211-class patrol boat or Gumdoksuri-class patrol vessel).
Development
The Republic of Korea Navy (ROKN) began development of the PKG class in 2003 after a Chamsuri-class (PKM-class) patrol boat was sunk during a naval clash with North Korean patrol boats on June 29, 2002. The codenamed PKX (Patrol Killer eXperimental) program is the patrol boat modernization project of the ROKN.
The PKX consist of two main designs. The larger, missile armed, PKX-A(PKG) of approximately 500 tons and the smaller, gun and rocket armed, PKX-B(PKMR) of approximately 200 tons. PKX-A(PKG) is planned to take up some of the operations done by Pohang-class corvettes, and the PKX-B(PKMR) is planned to replace the aging Chamsuri-class fleet.
The first PKX-A(PKG) vessels were ordered from Hanjin Heavy Industries. The lead ship of the class, Yoon Youngha, named after Lieutenant Commander Yoon Youngha who was killed during the second battle of Yeonpyeong, was launched on June 28, 2007 and commissioned on December 17, 2008. The production of the PKX-A(PKG) are being divided between Hanjin Heavy Industries and STX in lots of four.
This brief starts where responsible research should: with the source description of “Yoon Youngha-class patrol vessel” as ship class. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as ship class. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q217721. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2003, 2002, 2007 and 2008.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
