The Chang Bogo Class includes nine submarines. The ROKN placed an order for the construction of three submarines in 1987. The first boat in class, ROKS Chang Bogo (SS-61), was launched in June 1992 by HDW at Kiel, Germany. The remaining two subs were built by Daewoo at Okpo in South Korea, using German-supplied materials.
