Development
The Republic of Korea Navy 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 ROK Navy.
The PKX consist of two main designs. The larger, missile armed PKG-A of approximately 500 tons and the smaller gun armed PKG-B of approximately 200 tons. PKG-A is planned to take up some of the operations done by Pohang class corvettes, and the PKG-B is planned to replace the aging Chamsuri-class patrol vessel fleet.
The first PKG-A vessel were ordered from Hanjin Heavy Industries. The lead ship of the class, Yoon Youngha (PKG 711), 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 PKG-A are being divided between Hanjin Heavy Industries and STX in lots of four.

Famous quotes containing the word development:
“Ultimately, it is the receiving of the child and hearing what he or she has to say that develops the child’s mind and personhood.... Parents who enter into a dialogue with their children, who draw out and respect their opinions, are more likely to have children whose intellectual and ethical development proceeds rapidly and surely.”
—Mary Field Belenky (20th century)
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.”
—Lawrence Kutner (20th century)
