Project history: Western nickname derives from the probably erroneous belief that Yugoslavia provided some design and technical support input to this extremely primitive design. Primarily intended for the insertion of saboteurs and other special forces personnel and operated for (and possibly by) the Reconnaissance Bureau of the Ministry of the People’s Armed Forces rather than the navy proper.The casing and sail are made of GRP. There are 10 watertight compartments to the pressure hull. Small arms and antitank rockets are carried for the saboteur swimmers, as is a rubber boat.
Modernizations: none
Naval service: One unarmed unit was caught in a fishing net off the northeast coast of South Korea on 22-8-98 and after the murder/suicide of the nine-man crew was brought into a South Korean port; the craft was not equipped with a sonar system and had no torpedo tubes.
