Six Formidable Class multi-mission frigates have been built for the Singapore Navy. The first of class, RSS Formidable, was launched on 7 January 2004 at the Lorient dockyard in Brittany, France.
The Republic of Singapore Ministry of Defence (MINDEF) awarded the contract in March 2002 to DCN (now DCNS) in France for the design and construction of the frigates. The contract included a technology transfer programme under which the construction of the first frigate was carried out in France and then five further frigates were built in Singapore by Singapore Technology Marine (STM) at the Benoi shipyard. The frigate programme is named Project Delta and is being managed by Singapore’s state-owned Defence Science and Technology Agency (DSTA).
Following the launch of the RSS Formidable in January 2004, work started on fitting the combat and platform systems. The frigate arrived at Changi Naval Base, Singapore, in August 2005 and was commissioned in May 2007. The six Formidable Class frigates were declared fully operational in January 2009.

As well as RSS Formidable (68), the class consists of: RSS Intrepid (69) launched in July 2004, RSS Steadfast (70) launched in January 2005 and RSS Tenacious (71) launched in July 2005 – all commissioned in February 2008; RSS Stalwart (72), launched in December 2005 and delivered in October 2007; and RSS Supreme (73), launched in May 2006 and delivered in August 2008. Stalwart and Supreme were commissioned in January 2009.
The frigates replace the six Sea Wolf Class missile gunboats that entered service in 1972 and are approaching the end of operational life.
Sea Wolf Class missile gunboats
The Sea Wolf class missile gunboats were acquired in 1968, based on the TNC 45 design from Fredrich Lürssen Werft. The first two gunboats were constructed in Germany, while the remaining four were constructed locally by ST Marine (then known as Singapore Shipbuilding and Engineering).
As new technology became available, these gunboats underwent a number of upgrading programmes in the 1980s and 1990s to increase their strike capability and sophistication. These gunboats became the first missile-armed naval vessels in Southeast Asia when they were upgraded to launch Boeing Harpoon (SSM) surface-to-surface missiles. On 13 May 2008, all six gunboats were retired at a sunset decommissioning ceremony held at Changi Naval Base following 33 years of service.

(F-710) La Fayette
A high level of automation and closely integrated combat and ship management systems have been selected to allow the frigate to be operated with a crew of just 70. The overall length is 114.8m with a beam of 16.3m and draught of 6.0m. The full load displacement is 3,200t.
Command and control
The combat management system was developed by the state-owned DSTA with ST Electronics to meet the operational requirements of the Republic of Singapore Navy. DSTA also has responsibility for the combat systems integration. The standard operating common consoles, with 20in LCD displays, are supplied by Singapore Technologies Electronics, a subsidiary of ST Engineering.
Combat management system
The Integrated Communications System is also supplied by Singapore Technologies Electronics.
The frigate is armed with the Boeing Harpoon surface-to-surface anti-ship missile. The Harpoon missile has a range of 130km and uses active radar guidance. The missile is armed with a 227kg warhead.
Harpoon anti-ship missile
The Harpoon is an all weather, subsonic, over the horizon, anti-ship missile which can be launch from surface ships, submarines and aircraft. Its guidance system consists of a 3-axis integrated digital computer/ radar altimeter for midcourse guidance, and an active radar seeker for the terminal phase of the flight.
The Harpoon flies at subsonic speeds, with a sea-skimming flight trajectory for improved survivability through reduced probability of detection by enemy defenses. It was designed to strike enemy ships in an open ocean environment.
The ship launched RGM-84 Harpoon was introduced in 1977, as well as the encapsulated submarine launched UGM-84.

The frigate is fitted with the DCNS Sylver vertical launch system with MBDA Aster 15 surface-to-air missiles. There are four eight-cell SYLVER A43 launch modules with 32 missiles. The two-stage Aster missile is a high-agility and high-manoeuvrability defence missile for deployment against incoming sea skimming anti-ship missiles which use evasive terminal manoeuvres and re-attack modes. In anti-missile mode the Aster 15 has a range of 15km. Aster also provides protection against manned and unmanned aircraft to a range of 30km.

ASTER 15 – Image: from the web
The two-stage ASTER missiles are provided with two different solid propellant boosters resulting in the ASTER 15 and the ASTER 30 models. The ‘Pif-Paf’ control system enables the ASTER missile to counter high maneuverable missiles achieving a direct impact (hit-to-kill). The ‘Pif-Paf’ propulsion combines conventional aerodynamic control with control by gas jets acting through the centre of gravity of the missile. Until mid-course the guidance of an ASTER missile is based on the Inertial Navigation System (INS) updated through an uplink, in the terminal phase the guidance is provided by an active Radiofrequency seeker. The final stage of the ASTER missile is a ‘dart’ equipped with the seeker, a sustainer motor, a proximity fuze and a blast fragmentation warhead.

The ASTER 15 is a short range missile intended for self-defense (point defense) purposes against highly maneuverable threats. The ASTER 15 is integrated on the SAAM and beginning in 2006 in the PAAMS system. The SAAM is installed on French-built frigates and the Charles de Gaulle aircraft carrier. The PAAMS will be provided to the Horizon frigates (France and Italy) and the Type 45 destroyers (United Kingdom).

Three Sagem Défense Sécurité (formerly EADS Defence & Electronics) new-generation Dagaie systems (NGDS) are fitted. Each system consists of a pair of two-axis launchers with 12 infrared, radar or acoustic decoys.
Dagaie systems (NGDS)
Each of the vessels is equipped with three eight (8) barrel 130mm Sagem NGDS (New-Generation Dagaie System) multiple decoy launchers to counter a variety of threats such as anti-ship missiles and torpedoes. Two decoy launchers are in front of the bridge and behind the VLS while the third one is located at the top of the helicopter hangar (it seems that the third launcher has been removed from the vessels). NGDS is integrated in the ship’s combat system’s detection and warning system and can react automatically to current or emerging threats, in extremely short times. Each system is equipped with a single dual launcher including decoys (infrared, radar or acoustic) adapted to the threat to be neutralized. The NGDS system adapts to all types of munitions: electromagnetic or IR decoys, Active Offboard Decoy (AOD), Anti-Torpedo Decoy and/or laser jammer, deployed at short, medium or long range. The launchers are linked to a computer that selects the decoying best-suited technique. The Electronic Warfare Coordination Center provides the commanding officer with the ship’s tactical situation and coordinates the various Electronic Warfare (EW) tactics: threat evaluation, tactics optimization, coordination of decoys, radar jammer and more generally, electronic countermeasures Electronic Support Measures (ESM).

The new configuration is two forward launching systems replacing the two previous NGDS and two WASS countermeasure launching systems atop the hangar. Source navalanalyses.blogspot.com
Leonardo-Finmeccanica WASS anti-torpedo defence countermeasure launching system
The C310 represent Defence Systems Division’ high-performance anti-torpedo countermeasure system. It’s designed to resist the attacks of the most technologically advanced torpedoes, wire-guided or not (launch-and-forget)
They are realized with electronic items that generate disturbance noise for the acoustic head of the enemy torpedo.
This kind of countermeasure can both represent dummy mobile targets (MTE) and generate disturbance noise for the acoustic head of the enemy torpedo (Jammers). The combination of mobile Decoys and Jammers has the purpose of cheating the torpedo, which directs its attacks towards the dummy targets, thus allowing the ship to perform an evasive countermeasure.
The definition of optimal reaction results using a elaboration software (ORACOM) that, based on multiple parameters, elaborates the more suitable operation to maximize surviving probabilities, even against last generation torpedoes with high potentials against contermeasures.
