HSwMS Sjöhästen (Shä), Sw. meaning sea horse, was the fifth and last 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 Sjöhästen was sold to Singapore on 28 May 1999. She was never commissioned instead used as for spare parts.
