[1] The seized Sang-O-class submarine was placed on display at Unification Park near Gangneung, which was opened on 26 September 2001.[5] They are usually equipped with four 533 mm (21 in) torpedo tubes and 16 mines, but some are unarmed and are used to carry North Korean commandos.Subsequent satellite imagery shows the Sang-O II / K-300 deployed to the Ch’aho-rodongjagu submarine Navy Base at 40.205441 N 128.649524 E on North Korea's east coast.[8] According to the KPA Journal,[2] the decision to develop a larger, improved version of the Sang-O came in the late 1990s or early 2000.Top speed is also reported to be higher in the new model, meaning an improved propulsion system is possibly housed in some of the extra length.
