Radar: Surface search I-band SAS Charlotte Maxeke (S102) is a Heroine-class submarine, a variant of the Type 209 diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft (HDW) of Germany, currently in service with the South African Navy.

[2] The sponsor of S102, Mrs. Mittah Seperepere named the submarine at a ceremony in Emden, Germany on 14 March 2007.

[3] South Africa placed a contract for three Type 209/1400 submarines in July 2000 on Howaldtswerke-Deutsche Werft (HDW) and Thyssen Nordseewerke.

The Heroine class are sometimes considered to be South Africa's first "true" submarines, as they were more suited to being underwater than the Daphné models.

Funding in the amount of R189 million had reportedly been made available to ensure the completion of the refit during the 2023/24 financial year.
