History
editThe Indonesian variant is based on the Sigma 9113 design.[5] Work on the first of the class, KRI Diponegoro, began with the first steel cutting conducted in October 2004. The ship was christened on 16 September 2006 and commissioned on 2 July 2007 by Admiral Slamet Soebijanto, Indonesian Navy Chief of Staff.[6]
Options for two other units were exercised in January 2006 with the first steel cut commenced on 3 April 2006[7] in Damen's Schelde Naval Shipbuilding yard, Vlissingen-Oost yard and not in Surabaya stated earlier.
On 28 August 2007, Jane's Missiles and Rockets reported[8] that Indonesia was having problems securing the export license for the MM-40 Exocet block II and are considering Chinese made C-802 anti-ship missiles as alternatives. However, the ships have already been delivered with the Exocet missiles. In 2019 MM40 Exocet Block III were launched from KRI Sultan Iskandar Muda (367).[9]
Modernisation
editIn early November 2022, PT Len and Thales Nederland has signed a contract to undertake the refurbishment of the integrated mission systems for all four Diponegoro-class ships. These ships will soon be refurbished with an Integrated Missions System including the TACTICOS Baseline 2 Combat Management System, the Naval Smarter (NS) 50 radar, as well as the latest in software-driven radar technology able to combat the highest level of threats.[10][11]
