Sigma-class corvette - Indonesian Navy - KRI Sultan Iskandar Muda From Wikipedia, the free encyclopedia The Sigma class corvette is a Dutch-built Navy vessel. It is a corvette or frigate with ocean capabilities. Modular design[edit] The basic design of the Sigma Patrol Series can vary as the hull segments are designed as components. Ships can vary in the number of hull segments and in the order in which they are placed. Sigma stands for Ship Integrated Geometrical Modularity Approach. The ship's main dimensions are named in the types itself, SIGMA 9113 stands for 91 meters long and 13 meters wide, same is with the SIGMA 10513, 105 meters in length and 13 meters wide. The design was derived from the earlier High Speed Displacement hull form by MARIN Teknikk AS in the 1970s. SIGMA 9113 The Indonesian variant is based on the Sigma 9113 design.[7] Work on the first of the class, KRI Diponegoro, began with the first steel cutting conducted in October 2004. The ship was christened on September 16, 2006 and commissioned on July 2, 2007 by Admiral Slamet Soebijanto, Indonesian Navy Chief of Staff.[8] Options for 2 other units were exercised on January 2006 with the first steel cut commenced on 3 April 2006[9] in Damen's Schelde Naval Shipbuilding yard, Vlissingen-Oost yard and not in Surabaya stated earlier. In 28 August 2007, Jane's Missiles and Rockets reported[10] 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.
