In September 2023, a routine South African Navy drill turned into a tragedy when an abnormal wave hit the SAS Manthatisi submarine, taking the lives of three sailors. Despite their utmost efforts, they were unable to prevent the catastrophe. The aftermath led to several improvements in the safety regulations of naval operations, including the replacement of life jackets with versions capable of supporting up to 270kg and the strengthening and shortening of the safety line. The legacy of the heroic sailors continues to inspire and is immortalized in the bravery of their comrades.
