The Diponegoro class of guided-missile corvettes of the Indonesian Navy are SIGMA 9113 types of the Netherlands-designed Sigma family of modular naval vessels, named after Indonesian Prince Diponegoro. Currently there are four Diponegoro-class corvette in service.
History
The Indonesian variant is based on the Sigma 9113 design.{{cite web|title=Indonesian Specifications of the Sigma Class coverttes|url=http://www.scheldeshipbuilding.com/sigmacorvette.htm|url-status=dead|archiveurl=https://web.archive.org/web/20110928162530/http://www.scheldeshipbuilding.com/sigmacorvette.htm|archivedate=2011-09-28|accessdate=2016-01-19|website=Scheldeshipbuilding.com}} 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.{{cite web|title=ANTARA News: Navy chief takes delivery of corvette made in Netherlands|url=http://www.antara.co.id/en/arc/2007/7/3/navy-chief-takes-delivery-of-corvette-made-in-netherlands/|url-status=dead|archiveurl=https://web.archive.org/web/20090410153424/http://www.antara.co.id/en/arc/2007/7/3/navy-chief-takes-delivery-of-corvette-made-in-netherlands/|archivedate=2009-04-10|accessdate=2016-01-19|website=Antara.co.id}}

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).{{Cite web|title=Kapal Perang TNI Luncurkan Peluru Kendali Exocet MM 40 Block-3|url=https://daerah.sindonews.com/artikel/jateng/8637/kapal-perang-tni-luncurkan-peluru-kendali-exocet-mm-40-block3|access-date=2021-02-03|website=SINDOnews.com|language=id-ID}}
Modernisation
In 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.
