The Makassar class is a class of 4 Landing Platform Docks designed for the Indonesian Navy by Daesun Shipbuilding & Engineering Co. of South Korea and based on the earlier Tanjung Dalpele class. The US$150 million contract was signed in December 2004 and the first two units were built in Busan, South Korea. The remaining two were built at Indonesia's PT PAL shipyard in Surabaya with assistance from Daesun. The 3rd and 4th units have been modified to act as flagships with provisions for a command and control system, 57mm gun and air defense systems.
