HSwMS Sjöormen (Sor), Sw. meaning sea serpent, was the lead ship of the Swedish submarine class Sjöormen, project name A11.[1]
Development
[edit]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 pioneering 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.
Service in Sweden
[edit]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
[edit]HSwMS Sjöormen was renamed RSS Centurion and Singapore reacquired the boat on 28 May 1999. She was commissioned on 26 June 2004 after a major refit. After 11 years in the Republic of Singapore Navy, she was decommissioned on 11 March 2015 and scrapped. Her fin and sail were preserved as a memorial at the Republic of Singapore Navy Museum.
