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.[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 September 16, 2006 and commissioned on July 2, 2007 by Admiral Slamet Soebijanto, Indonesian Navy Chief of Staff.[6]
Options for 2 other units were exercised on 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.
In 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.
SIGMA 10514
On the 16 August 2010, Indonesia Defense Department, signed a deal[9] with PT PAL Indonesia and Damen Schelde to build a 105 meters frigate in Indonesia based on Damen Schelde Sigma 10514 design. The frigate will be equipped with 76mm Main Canon, 12 MICA vertical launch air defence missile, MM-40 Exocet block II, Torpedo, Phalanx and Smart-S MK2 radar system.
On February 6, 2008,[10] Morocco signed a USD$1.2 billion contract with Schelde Naval Shipbuilding for two Light frigate SIGMA 9813 and one Light frigate SIGMA 10145 which are modified versions of the existing SIGMA Class design.
A subsequent contract was signed[11] on the April 1, 2008 with Thales Nederland for the supply and installation of the command and control and sensor package for the ships. The package included TACTICOS combat management system, SMART-S Mk2 surveillance radar, LIROD Mk2 tracking radar, Thales KINGKLIP sonar system, IFF system, Integrated communication system comprising external communication system and FOCON internal communication system, two Target Designation Sights, VIGILE ESM system, SCORPION ECM system, and the integrated navigation system.
The first frigate for Morocco, Tarik ben Ziyad, was launched in July 2010,[12] began sea trials on 6 May 2011[13] and was delivered on 12 September 2011.[14] The second ship was launched on 2 February 2011,[12] with sea trials planned for late in the year.[13] The third ship was planned to be launched in September 2011.[13]
