SIGMA 10514 PKR Guided-Missile Frigates, Indonesia

Two SIGMA 10514 Perusak Kawal Rudal (PKR) guided-missile frigates are being built by PT PAL Indonesia (Persero), in collaboration with Damen Schelde Naval Shipbuilding (DSNS) for the Indonesian Navy (TNI-AL).

Frigates are designed to perform various missions, including patrolling the exclusive economic zone (EEZ) of Indonesia, deterrence, maritime security, search-and-rescue, anti-surface, and electronic and anti-air warfare.

The frigates can also be used for humanitarian support tasks.

Orders and deliveries of SIGMA 10514 PKR frigates

The SIGMA 10514 PKR guided-missile frigate project was launched by the Indonesian Ministry of Defence in August 2010.

The ministry awarded a contract to DSNS for the construction of the first SIGMA 10514 PKR frigate in December 2012. First steel was cut in January 2014, and the keel was laid in April 2014 at lead integrator PT PAL’s shipyard in Surabaya, Indonesia.

Four of six core modules were built at Surabaya shipyard, while the remaining two were constructed and tested at Vlissingen shipyard in the Netherlands. The ship was launched in January 2016 and her sea trials were completed in September 2016. It was delivered in January 2017.

A contract for the construction of the second guided-missile frigate was signed in February 2013. The first steel was cut in September 2014 and the keel-laying ceremony was held in December 2014.

In November 2013, Thales was awarded a contract by DSNS to deliver a full mission systems suite for the first two frigates.

Indonesian state-owned shipbuilder PT PAL has begun sea trials of the country’s first SIGMA 10514 Perusak Kawal Rudal (PKR) guided-missile frigate on order for the Indonesian Navy (Tentara Nasional Indonesia – Angkatan Laut, or TNI-AL).

The vessel, which will be the future KRI Raden Eddy Martadinata (331), began its sea trials in the week starting 11 July in waters off Ujung, Surabaya. The trials included a speed test, a crash stop test, and turning manoeuvres, the company told IHS Jane’s on 18 July.

Indonesian Navy receives second PKR frigate KRI I Gusti Ngurah Rai: Here


The Indonesian Navy received its second Perusak Kawal Rudal (PKR) guided-missile frigate KRI I Gusti Ngurah Rai during a ceremony in Surabaya, Indonesia, on October 30.

Named after the Indonesian War of Independence hero who fought against the Dutch between 1945 and 1949, KRI I Gusti Ngurah Rai is the second of two frigates built by Indonesian shipbuilder PT Pal and Dutch shipbuilder Damen through a transfer of technology agreement.

Based on Damen’s Sigma 10514 design, the vessels are built using a collaborative modular process operating simultaneously at Damen Schelde Naval Shipbuilding (DSNS) in the Netherlands and PT PAL shipyard in Indonesia.

The ship features a helicopter hangar and an aft flight deck with astern fuelling capabilities to hold and operate a 10t helicopter during day and night. It can carry two rigid hulled inflatable boats (RHIBs) for patrol and transport operations.

Weaponry and countermeasures aboard the frigate

The guided-missile frigate is armed with a close-in weapon system, a 76mm medium-calibre gun, two SSM launchers, and a 12-cell vertical launch short-range air defence system (VL SHORADS).

Exocet MM40 Block 3


The MM40 Block 3 missile, complete with a Microturbo TRI 40 turbojet engine, began development 2004 and was first tested from a ship in 2010. Improvements to the MM40 Block 3 include internal navigation and GPS upgrades. These updates, combined with a frequency modulated continuous wave radar altimeter, allows for control of the missile’s altitude over various types of terrain. This missile is armed with a 160 kg high explosive/semi-armour piercing warhead and an active radar terminal seeker 9 Additional upgrades include increased evasive capabilities such as the ability to make a 180 degree turn post-launch, allowing the MM40 to evade defense missile systems. These upgraded missiles will be both ship- and ground-launched and will be deployed first onto Forbin (Horizon)-class destroyers and then to La Fayette-class frigates.

12-cell vertical launch short-range air defence system

The VL MICA is a weapon system with an unmatched self-defence and local area defence capability for a wide range of surface combatant vessels VL MICA is available with two state-of-the-art seekers (IR or RF).

It can counter the most severe IRCM-ECM scenarios with a very high kill probability.

VL MICA offers a real multiple target capability (autonomous guidance, extremely short reaction time) and all target capability (aircraft, missiles, PGMs, smart bombs and helicopters) with low training costs and reduced manpower requirements.
MICA VL Launch cellsVL MICA is integrated to the ship combat system, which provides target designation data from existing air defence sensors. No dedicated fire control system is needed (neither illuminator nor radar tracker).

The missile is launched from an individual storage container (no additional VLS), providing 360° engagement coverage and maintaining ship stealth and stability. The system compactness and modularity enable installation on a wide range of warships for new built or refit.

The VL MICA has already been procured by several navies all over the world. Source

Two triple torpedo launchers are provided for anti-submarine warfare. The ship is also equipped with guided-missile systems and gun systems for anti-air warfare, as well as anti-surface warfare operations.

Its countermeasure capabilities include two decoys / chaff, electronic support measures (ESM), and electronic countermeasures (ECM).


Sensor suite

The SIGMA 10514 PKR incorporates STIR 1.2 Mk2 electro-optical (EO) fire control system, identification friend or foe (IFF), KINGKLIP hull-mounted sonar, SMART-S Mk2 3D multi-beam surveillance, and target indication radar.

STIR 1.2 Mk2 electro-optical (EO) fire control system


STIR 1.2 EO Mk 2 is the main fire control. R-ESM capability rely on Vigile Mk 2. L3 Wescam MX-10MS optronic surveillance system and Terma SKWS C-Guard (Example May not be exact model)

KINGKLIP hull-mounted sonar


KINGKLIP is particularly efficient to detect submarines in rough sea states and coastal/littoral waters, where difficult reverberation conditions prevail.

Naval version (“shipborne”)
Link Y Mk2 is built in a compact housing compliant to military standards that meet the requirements for equipment in a naval environment. The naval version is to be integrated into any Combat Management System, e.g. TACTICOS, for surface vessels or submarines. Alternatively, the naval version can be delivered with a local control station to act as a standalone system on board. Source

SMART-S Mk2 3D multi-beam surveillance, and target indication radar

05-03-2007_THALES SMART-S

SMART-S MK2 3D MEDIUM TO LONG RANGE SURVEILLANCE RADAR Thales’s latest 3D multibeam radar, operates in S-band and is optimised for medium-to-long-range surveillance and target designation in littoral environments. The latter consisting of a mix of sea, land, islands, coastal rains and thunderstorms and a multiple of radar targets including small surface targets, helicopters and anti-ship missiles. Furthermore, SMART-S Mk2 is designed to match the full performance of surface to air missiles (SAM), such as the Evolved Sea Sparrow Missile (ESSM). SMART-S Mk2 is extremely suitable as the main air and surface surveillance radar in a one radar concept for light frigates, corvettes and ships such as Landing Platform Docks (LPD). With its 2 main modes, 250-km range, special helicopter mode, surface fire channels.

The onboard Tacticos combat management system designed by Thales integrates the ship’s sensors, weapons and other equipment to provide real-time situational awareness.

Propulsion of the guided-missile frigate


The combined diesel or electric (CODOE) propulsion system consists of two 10,000kW maximum continuous rating (MCR) diesel engines, two 1,300kW electric motors, two double input / single output gearboxes, and two 3.55m controllable pitch propellers.

Auxiliary units include six 715kWe generator sets, an 180kWe emergency generator set, two redundant distribution chilled water systems, degaussing and fire-fighting system with four main and one service pump.

Performance of SIGMA 10514 PKR frigate
