    HSwMS Sjölejonet (Sle), Sw. meaning sea lion, was the second ship of the Swedish submarine class Sjöormen, project name A11.[1]

    Development[]

    The planning of the class included a number of different AIP solutions including nuclear propulsion. However, the ships where finally completed with for the time extremely large batteries. The ship was a single-hulled submarine, with hull shape influenced by the American experimental submarine USS Albacore. The hull was covered with rubber tiles to reduce the acoustic signature (anechoic tiles), at this time a pioneer technology. The Sjöormen class also pioneered the use of an x-shaped (as opposed to cross-shaped) rudder as a standard (as opposed to experimental) feature.[2]

    Service in Sweden[]

    The submarine served in the Swedish Navy for almost 30 years and was then sold to Singapore in 1997 together with its four sister ships.

    Service in Singapore[]

    HSwMS Sjöbjörnen was renamed RSS Conqueror and Singapore reacquired the boat on 28 May 1999. She was commissioned into the Republic of Singapore Navy on 26 June 2004 after a major refit and remains in active service as of 2020.
