South African Naval Museum

SAS Assegaai, formerly known as SAS Johanna van der Merwe, was a Daphné-class submarine of the South African Navy. Decommissioned in 2003, SAS Assegaai is the only one of the former three Daphné-class submarines to have been retained for preservation as a museum boat, the other two have been cut up and sold for scrap. The Daphné-class submarines have since been replaced by the Type 209, or Heroine-class submarines.
