The SAS Assegaai, formerly known as the SAS Johanna van der Merwe, was a Daphné-class submarine of the South African Navy. Decommissioned in 2003, the SAS Assegaai is the only one of the former 3 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 The Daphné class submarines have since been replaced by the Type 209, or Heroine-class submarine.

Daphné Class submarines

On 10 February 1967, after nearly two years of negotiations, an order was placed with the French Government to provide three Daphné (Dolphinr) class submarines in addition to providing the training and infrastructure to run and maintain them. The first of these submarines, the SAS Maria van Riebeek (S97), was launched on 18 March 1976 - the date accepted[by whom?] as being the birth of the SAN's submarine service. The second boat was the SAS Emily Hobhouse (S98), and the last of the three, the SAS Johanna van der Merwe (S99).[1] In 1999 the three boats were renamed SAS Spear, SAS Umkhonto and SAS Assegaai respectively. In 2003, the SAS Spear was cut up for scrap, followed by the SAS Umkhonto in 2008 while SAS Assegaai is being preserved as a museum exhibit.[2]

History

Laid down at the Dubigeon-Normandy shipyard in Nantes on 24 April 1969, she was the launched on 21 July 1970.[3] Commissioned under command of Lt Cdr Theo Honiball on 21 August 1971, she completed her workup training in the Mediterranean, operating out of Toulon, before sailing for home on 4 May 1972. During the long passage, she was escorted by the frigate SAS President Steyn, and called at Cadiz, São Vicente, Luanda and Walvis Bay, before arriving in Simon's Town on 19 June 1972. Her arrival in South Africa marked the successful culmination of five years of construction, trials and training to establish South Africa's first ever submarine capability. It was not long before the submarines were involved in operations, and in 1975, just before Operation Savannah (Angola), the SAS Johanna van der Merwe was deployed into Angolan waters under Operation Yskas to prepare for the evacuation of SA military personnel. During the South African Border War, she took part in some ten clandestine special operations.[citation needed]

During her career, she underwent four refits, which included installing additional fuel tanks, and the fitting of a locally developed RAKA combat suite in the 80s, which replaced a cumbersome plotting table. In the late 90s she received the South African developed NICKLES fully integrated software based combat suite and two state of the art rebuilt periscopes.[4] With the acquisition of the new Type 209 submarines for the SA Navy, SAS Assegaai finally paid off on 23 November 2003.

Museum boat

The SAS Assegaai has been converted into a museum ship and is stationed in Simon's Town.[5][6] A project that has been spearheaded by the South African Naval Heritage Trust, the SAS Assegaai is a part of the South African Naval Museum.[7]
