The R.E. Martadinata-class of guided-missile frigates of the Indonesian Navy are SIGMA 10514 types of the Netherlands-designed Sigma family of modular naval vessels, named after Indonesian Admiral Raden Eddy Martadinata. The frigates are each built from six modules or sections, four built at the PT PAL shipyard at Surabaya, the other two at Damen Schelde Naval Shipbuilding in the Netherlands.^[​2] Currently only 2 R.E. Martadinata-class frigates have been ordered, however, with the planned retirement of the Ahmad Yani-class frigates it is widely expected that more R.E. Martadinata-class frigates will be ordered and built.
