SAS Assegaai, formerly the SAS Johanna van der Merwe, was one of three Daphne-class submarines acquired from France during 1970 to 1972, which became the first submarines to serve in the South African Navy. She was renamed SAS Assegaai (Assegaai is the Afrikaans word for 'spear') in 1999 and was the last of the SA Navy’s Daphne class submarines in commission and finally decommissioned in 2003. Currently she is preserved as a floating museum but will be preserved ashore at the Naval Museum by 2013.
