The SIGMA class is a Dutch-built family of modular naval vessels, of either corvette or frigate size, designed by Damen Group.
SIGMA stands for Ship Integrated Geometrical Modularity Approach. [4] 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. The ship's dimensions of length and beam lead to the individual SIGMA type names: the SIGMA 9113 is 91 m (298 ft 7 in) long with a beam of 13 m (42 ft 8 in), the SIGMA 10513 is 105 m (344 ft 6 in) in length again with a beam of 13 m (42 ft 8 in)
The design was derived from the earlier High Speed Displacement hull form by Marin Teknikk AS in the 1970s.[ citation needed ]
There are three types of Sigma combatants

There are multiple new SIGMA designs released in early 2015 these are the:
They are likely to be part of the Compact SIGMA series, a new series small sized combatants with shorter range and up to 2 weeks mission endurance with the same combat systems as the larger version. [16]
The Indonesian variant is based on the SIGMA 9113 design. [37] Work on the first of the class, KRI Diponegoro (365), 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. [38]
Options for two other units were exercised in January 2006 with the first steel cut commenced on 3 April 2006 [39] in Damen's Schelde Naval Shipbuilding yard, Vlissingen-Oost yard and not in Surabaya as stated earlier.
On 28 August 2007, Jane's Missiles and Rockets reported [40] that Indonesia was having problems securing the export license for the MM40 Exocet block II and was considering Chinese made C-802 anti-ship missiles as alternatives. However, the ships have already been delivered with the Exocet missiles.
In 2018 Thales has upgraded the Indonesian Navy's Diponegoro-class corvette through the installation and refurbishment of the Kingklip hull-mounted sonar system. [41]
In 2019 the Diponegoro-class corvettes were upgraded with MM40 Exocet block III missile. [42]
On 31 August 2021, Terma announced that they have been awarded a contract for the upgrade of existing C-Guard systems with Anti-Submarine Warfare (ASW) capabilities for the Sigma-Class Corvettes of the Indonesian Navy. This C-Guard ASW upgrade program is a follow-on from the previous ASW upgrade contract awarded in 2019 for the same class of ships. [43]
On 4 November 2022, Thales has signed a contract with PT. Len to undertake the refurbishment of the integrated mission systems for Diponegoro-class ships. [44] The corvettes will be updated with Thales TACTICOS Baseline 2 combat management system (CMS) and the Naval Smarter (NS) NS50 radar system. [45]
On the 16 August 2010, Indonesian Defense Ministry, signed a deal [46] [47] with PT PAL Indonesia and Damen Schelde to build a 105-meter frigate in Indonesia based on Damen Schelde SIGMA 10514 design. For the first ship, five modules for the ship will be built in Indonesia and the Dutch manufacturer Damen Schelde will build 2 modules while for the second ship the Indonesians will build six modules and Damen Schelde will build one module.
On 1 February 2013 it was announced that a second unit will be built by Damen Schelde Naval Shipbuilding and PT PAL Surabaya, the second contract includes torpedo tubes, combat control room and a couple of surface weapons.
They were built without several of their main system and equipment, namely VL-MICA, MM40 Exocet block III, Rheinmetall Millennium CIWS, Electronic warfare system and were planned to be installed later on (FFBNW). [48]
As of December 2015, the first ship, KRI Raden Eddy Martadinata (331), was 85% complete and the ship was launched on 18 January 2016. [49] [50] [51] On 7 April 2017 the first ship, KRI Raden Eddy Martadinata (331), was commissioned at Tanjung Priok. [52] The second ship, KRI I Gusti Ngurah Rai (332), was commissioned on 10 January 2018. [53]
The class finally received their full complement of FFBNW system and equipment in December 2019 for KRI Raden Eddy Martadinata (331) [54] and March 2020 for KRI I Gusti Ngurah Rai (332). [55]
On 6 February 2008, Morocco signed a USD$1.2 billion contract with Schelde Naval Shipbuilding for two light frigate SIGMA 9813 and one light frigate SIGMA 10513, which are modified versions of the existing SIGMA-class design. [56]
A subsequent contract was signed on 1 April 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. [57]
The first frigate for Morocco, Tarik ben Ziyad, was launched in July 2010, [58] began sea trials on 6 May 2011 [59] and was delivered on 12 September 2011. [60] The second ship was launched on 2 February 2011, [58] with sea trials planned for late in the year. [59] The third ship was planned to be launched in September 2011. [59]
On 18 August 2017, Damen announced the keel laying for one SIGMA 10514 Long Range Ocean Patrol Vessel (SIGMA 10514 LROPV/ SIGMA 10514 POLA) at Damen Schelde Naval Shipyard in Vlissingen for the Mexican Navy. The vessel was constructed modularly in six modules, two modules were constructed in Vlissingen and the other four modules in Mexico.
According to the Defense Security Cooperation Agency Major Arms Sale notification on 5 January 2018, the primary weapon systems for the SIGMA class will include RGM-84L Harpoon Block II, RIM-162 ESSM [61] with eight cell MK 56 VLS launcher, MK 54 Mod 0 lightweight torpedoes with two MK 32 Surface Vessel Torpedo Tubes (SVTT) triple tube launchers, Block II Rolling Airframe Missile (RAM) missiles and Bofors 57 mm gun. [62]
In April 2018 Damen Group contracted Spanish defense technology company Indra to equip the Mexican Navy's new long-range offshore patrol vessel (POLA) with its RIGEL electronic defense system. [63]

The Holland-class ocean-going patrol vessels are a class of four ocean-going patrol vessels constructed for the Royal Netherlands Navy. They are designed to fulfill patrol and intervention tasks against lightly armed opponents, such as pirates and smugglers, but have much higher level electronic and radar surveillance capabilities which are used for military stabilization and security roles, short of outright war. Without sonar or long range weapons, they utilize the surveillance capabilities of the Thales integrated mast, which integrates communication systems and two four-faced phased arrays for air and surface search.
The Bung Tomo class is a class of three Indonesian multi-role corvettes or 'multi-role light frigate' (MRLF) by Indonesia. They were originally built for the Royal Brunei Navy, and named Nakhoda Ragam-class corvettes, but were ultimately bought by Indonesia and subsequently renamed. The class is named after Bung Tomo, a noted leader of Indonesia's independence movement.
The Rheinmetall Oerlikon Millennium Gun or Rheinmetall GDM-008 is a close-in weapon system designed by Rheinmetall Air Defence AG for mounting on ships. It is based on the 35/1000 revolver gun land-based air defense system and uses Advanced Hit Efficiency And Destruction (AHEAD) ammunition.
SMART-S Mk2(Signaal Multibeam Acquisition Radar for Tracking, S band Mk2) is a naval medium to long-range air and surface surveillance multibeam passive electronically scanned array 3D radar designed by Thales Nederland, formerly Hollandse Signaalapparaten (Signaal). While the original SMART-S radar was only produced in small numbers, SMART-S Mk2 is more successful with 30 systems were sold to navies all over the world within six years after being introduced. The radar transmitter/receiver (T/R) modules for the radar are purchased by Thales from the Turkish defence company Aselsan.
The Maharaja Lela-class frigate, also known as the Littoral Combat Ship (LCS), is a class of six stealth frigates being built for the Royal Malaysian Navy (RMN). First announced as the Second Generation Patrol Vessel (SGPV) in 2011, the ships are based on an enlarged version of the Gowind-class corvette, designed by Naval Group, formerly known as DCNS of France.
The Ahmad Yani class of six general-purpose frigates were acquired by the Indonesian Navy in the 1980s. They were originally built in the Netherlands for the Royal Netherlands Navy as the Van Speijk class which were licence-built versions of the British Leander class.
The Raden Eddy Martadinata class of guided-missile frigates of the Indonesian Navy are SIGMA 10514 types of the Netherlands-designed Sigma family of modular naval vessels, named after Indonesian Admiral Raden Eddy Martadinata.
