Daphne Class (SSK)

A weapon systems upgrading (including sonar), as well as improved habitability as part of a mid-life improvement programme, was completed in Umkhonto in July 1988, Assegaai in late 1990. Assegai completed a four year refit on 19 May 1999 and Umkhonto became operational again in early 2001 after a short refit. Spear was ultimately sold as scrap in 2002. All Daphne Class submarines have since been withdrawn from service to be replaced by the new Type 209 submarines, with one retained for a museum.
