Yono-class submarine
North Korean Navy midget submarines
The Yono-class submarine (occasionally confused with Yugo-class) is a class of North Korean miniature submarines, produced for domestic use as well as for export. Also referred to as the Yeono class,[3] these submarines displace 130 tons, significantly less than North Korea's larger 1,800-ton Romeo-class submarines.[4] As of May 2010, North Korea is reported to operate ten of these submarines.[4] Iran is reported to have at least one Yono submarine and to have copied the design as the Ghadir-class.[5]
