Schelde Naval Shipbuilding

The Martadinata-class of guided-missile frigates of the Indonesian Navy are SIGMA 10514 types of the Netherlands-designed Sigma family of modular naval vessels. 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.

KRI Raden Eddy Martadinata (331), lead ship of her class, was commissioned on 7 April 2017 at Tanjung Priok. The second ship, KRI I Gusti Ngurah Rai (332), was launched in September 2016.
