SINGAPORE, -- The vessels, RSS Centurion and RSS Challenger were originally in service with the Royal Swedish Navy (RSwN) as HMS Sjöormen and HMS Sjöbjörnen and re-launched in May 1999 and September 1997 respectively. Singapore acquired four Type A 12 Sjöormen-class submarines in the mid-1990s to give the RSN its first experience of submarine operations.


The 51 m vessels, which can reach a top speed of 20 kt while submerged, are equipped with four 533 mm and two 400 mm torpedo tubes, according to IHS Jane's Fighting Ships.
