The vessel, which will be the future KRI Raden Eddy Martadinata (331), began its sea trials in the week starting 11 July in waters off Ujung, Surabaya. The trials included a speed test, a crash stop test, and turning manoeuvres.

Raden Eddy Martadinata was launched by PT PAL on 18 January at the company’s shipyard in Surabaya. The frigate is one of two platforms being constructed jointly by Dutch shipbuilder Damen Schelde Naval Shipbuilding (DSNS) and PT PAL under a contract signed with the Indonesian Ministry of Defence in June 2012.

According to specifications provided by PT PAL, the PKR frigate has a standard displacement of approximately 2,400 tonnes, can accommodate a crew of 120, and it can hold a 10-tonne helicopter on its flight deck. The platform has a top speed of 28 knots/32 mph/52 km/h, a maximum range of 5,000 nautical miles/5,754 miles/9,260 km at 14 knots/16 mph/26 km/h, and a standard range of 4,000 nautical miles/4,603 miles/7,408 km at 18 knots/21 mph/33km/h.

Raden Eddy Martadinata ‘s weapons include an Oto Melara 76-mm main gun, launchers for MBDA MM40 Exocet Block II anti-ship missiles, six (two triple) 324-mm Eurotorp B515 torpedo launchers, the Rheinmetall Defence Millennium 35-mm close-in weapon system, and a 12-cell Vertical Launch System (VLS) that can deploy the MBDA VL-MICA surface-to-air missiles.

The weapon systems will be completed with a modified version of Thales’ TACTICOS Combat Management System (CMS).

The platform is on track for delivery to the TNI-AL in January 2017.
