Development

File:ROKS No Jeok Bong.jpg

In the late 1980s the Republic of Korea Navy decided to gradually replace its aging fleet of World War II-era {{sclass|LST-542|tank landing ship}}s (renamed Un Bong-class LST) purchased from the US Navy in 1958. A three phase plan was laid out to develop new landing ships to meet the demands of modern amphibious and transport operations.

The first phase was designated as the LST-I project, and development and design started in 1987 by Korea Tacoma, currently Hanjin Heavy Industries. After 4 years of development, the lead ship Go Jun Bong (LST-681) was launched in 1991. Three more ships followed and all four ships were commissioned by 1998.

The second phase, or LST-II, was originally planned to import four {{sclass|Newport|tank landing ship}}s, but after being postponed due to budget issues, it was changed in favor for domestic built 4500-ton LPDs to be commissioned by 2013-2016.[http://news.chosun.com/site/data/html_dir/2007/10/09/2007100900842.html Chosun Daily - 4천500t급 차기상륙함 윤곽 드러나 10/9/2007] {{webarchive|url=https://web.archive.org/web/20071011014704/http://news.chosun.com/site/data/html_dir/2007/10/09/2007100900842.html |date=2007-10-11 }} After the construction of the first vessel, a follow-on contract for four additional vessels were awarded to Hyundai Heavy Industries in December 2013.{{cite web|url=http://english.yonhapnews.co.kr/full/2013/12/26/24/1200000000AEN20131226004800315F.html|title=S.
