The Raden Eddy 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.

These warships were designed as multi-mission frigates, able to fulfill the anti-aircraft warfare role with surface-to-air missiles, anti-surface warfare with Exocet missiles, anti-submarine warfare with hull mounted sonar, torpedoes and ASW Helicopters.
