Victory-class

The Victory-class corvettes are multi-purpose vessels operated by the Republic of Singapore Navy (RSN) in Singapore. Based on the MGB 62 design by Germany's Lürssen shipyard, the RSN ordered a squadron of six ships in 1983 to defend Singapore's sea lines of communication. The lead ship, RSS Victory, was built and launched by Lürssen Werft in Germany, while the remaining five ships—RSS Valour, RSS Vigilance, RSS Valiant, RSS Vigour, and RSS Vengeance—were constructed locally by Singapore Shipbuilding & Engineering. The corvettes were commissioned between 1990 and 1991 to form the Eighth Flotilla of the RSN.

Propulsion is provided by four MTU 16 V 538 TB93 high-speed diesel engines coupled to four shafts. For electronic warfare, the corvettes carry the Elisra SEWS electronic support measures system, the RAFAEL RAN 1101 jammer, two Plessey Shield nine-barrelled chaff launchers, and two twin RAFAEL long-range chaff launchers. Sensor systems include a Kelvin Hughes 1007 navigation radar and an Elbit MSIS optronic weapon control director.

Initially, the Victory-class corvettes served as the first RSN ships with anti-submarine warfare capabilities, carrying a Thomson Sintra TSM 2064 variable-depth sonar and EuroTorp A244/S Mod 1 torpedoes in two triple-tube launchers. Under a 1996 modernization program, the ships received rudder roll stabilization, a second fire control radar aft of the mast, an optronic director on the bridge roof, and two 8-cell vertical launching systems for IAI/RAFAEL Barak I anti-air missiles. The primary armament also includes eight Boeing Harpoon anti-ship missiles, one Oto Melara 76mm Super Rapid main gun, and four STK 50MG 12.7 mm heavy machine guns. During a Life Extension Programme announced in 2009, the original Ericsson/Radamec Sea Giraffe 150HC search radar was replaced by a Saab Sea Giraffe AMB radar. In 2012, the corvettes were fitted with a Boeing ScanEagle unmanned aerial vehicle, with RSS Valiant receiving the upgrade first. This modification resulted in the removal of the sonar and torpedo tubes.

During peacetime, the Eighth Flotilla has undertaken regional search and security operations. In 2014, RSS Vigour deployed to the South China Sea to support search efforts for Malaysia Airlines Flight MH370. The following year, RSS Valour participated in multinational search operations for Indonesia AirAsia Flight 8501. RSS Valour also supported security operations for the DPRK-USA Singapore Summit in 2018. In 2018, the Ministry of Defence announced that all six Victory-class corvettes would be replaced by new multi-role combat vessels.
